General Description
Pow-R-Command 100
The Pow-R-Command 100 System’s network of devices allows a
facility’s electrical use to be efficiently managed. With the Pow-RCommand 100, individual loads can be switched through a network of
individual panels, which are influenced by building automation systems, wall switches, time schedules, software, or through telephone
commands, etc. For more information on the Pow-R-Command 100
system, see Technical Document TD01412010E.
Universal System Controllers (USC)
The USC is the most commonly used controller in a Pow-R-Command
100 system. The USC has two functions: to communicate across the
network with other Pow-R-Command 100 controllers and to coordinate switching of lighting control devices such as Smart
Breakers or relays.
To aid in the second function, the USC100 is equipped with a number
of inputs and outputs:
SOC Inputs
As mentioned, the SOC is a printed circuit board that when applied in
the field is attached to a second printed circuit board. The SOC card
itself contains 12 low voltage 2-wire digital inputs, which provide
proper wetting voltage to detect change of state in inputs.
The second printed circuit board contains termination points for 48
low voltage 2-wire inputs. When the SOC is attached to the second
printed circuit board, all 48 low voltage 2-wire inputs act as if they are
resident on the SOC card itself. In order for the SOC to operate and
the 48 low voltage 2-wire inputs to work, the two pieces must be
used together. The two components are made separately so the
SOC card can be mounted both integral to a Pow-R-Command 100
panelboard or into a control cabinet. In either case, there are a total
of 60 low voltage 2-wire digital inputs available.
Examples of inputs to the SOC include:
●
Wall switches.
●
Photo light switches.
●
Proximity sensors.
●
Eight low voltage 2-wire universal inputs.
●
Building automation systems.
●
Four low voltage 2-wire digital inputs.
●
Mechanical control systems.
●
Three low voltage 2-wire analog outputs.
●
Security/access control systems.
The USC1000 offers inputs and outputs as follows:
●
Eight low voltage 2-wire universal inputs.
●
Eight low voltage 2-wire digital inputs.
●
Four low voltage 2-wire analog outputs.
●
Eight low voltage 2-wire digital outputs.
Optional 32 24 Vdc
Digital Outputs
In some applications, the inputs available on the USC are not enough
to provide the necessary capability. For this reason, the Switch
Override Controller (SOC) was created.
The Switch Override Controller
In a Pow-R-Command 100 System, the SOC is an optional controller
that communicates the status of inputs to USCs and other controllers
attached to the network. When an input changes state (e.g., from
OFF to ON), the SOC registers that change and sends a message to
the appropriate devices informing them of this change of state and
any actions the device should take. Because of this, the SOC
becomes a very useful tool in managing a large number of inputs.
Physically, the SOC is a printed circuit board. When the SOC is integrated into a panelboard or a separate control cabinet, it attaches to
a second printed circuit board which contains termination points for
48 inputs. Additionally, the SOC receives operating power from the
second printed circuit board. A third printed circuit board may be
attached to the SOC to provide additional digital outputs.
SOC Features
The SOC offers a number of control features, including:
●
Resident scheduling of inputs, including “Time of Day” and
“Holiday” scheduling.

Digital Input Specifications
The SOC can work with most types of inputs. Two requirements of
the inputs are that they contain a dry contact, and that the dry contact
is rated for continuous operation at 28 Vac. Inputs can be either
momentary or maintained and either normally-closed or normallyopen. The type of input depends on the desired outcome.
●
Complete integration into a Pow-R-Command 100 network.
●
Unique local address in the system.
●
Resident processor and memory for programming and schedules.
●
48 low voltage 2-wire switch inputs.
All digital inputs must contain a dry contact. The contact must be dry
because the SOC provides the proper wetting voltage (28 Vdc) to
detect change of state in the dry contact of the input. Inputs should
be attached to the SOC with 18 AWG wire and cannot be more than
500 feet (152 m) away from the SOC.
●
Eight low voltage 2-wire universal (digital or analog) inputs.
Universal Input Specifications
●
Three low voltage 2-wire analog outputs.
Each SOC has eight low voltage 2-wire universal inputs available for
use. Typically, these inputs are used for analog photo light sensors or
thermostats, but alternately, they can also function as digital inputs.
When utilizing the digital input function, use dry contact closure
devices.

All universal inputs on the SOC are capable of registering 0 – 5 Vdc
signals from the device.
Inputs are connected using 18 AWG stranded wire and can be a
maximum distance of 500 feet (152 m) away from the SOC.

Analog Outputs
Programming an SOC
The SOC card is equipped with three low voltage 2-wire analog outputs.
These analog outputs have a variety of uses, but are commonly used
for control of 0 – 10 Vdc dimmable electronic ballasts. For information
on 0 – 10 Vdc dimmable electronic ballast control, see Technical
Document TD01412019E.
Each SOC can be programmed either through the network or locally
at the device. The SOC’s unique address can be identified and controlled through software. For networking the Pow-R-Command 100
system, see Technical Document TD01412014E.
The SOC also provides a 15 Vdc power source for the sensors
attached to the analog inputs.

The Pow-R-Command 100 network operates on an RS-485 signal.
Each SOC has an RS-485 test port to provide the ability to locally
access the SOC card. The card can be programmed locally through
either a PC or a Pocket PC. For information about interfacing with a
Pow-R-Command 100 system through PCs or Pocket PCs, see
Technical Document TD01412016E.

Scheduling with an SOC
Each SOC has a resident processor and memory. Because of this,
programs can be stored on and processed by the SOC they reside on.
Typical schedules include Time of Day and Holidays. Though the SOC
contains the ability to set schedules, it is more common to have all
scheduling reside on the USCs located throughout the system.
Status Capabilities
There are two methods of indicating the status of the inputs attached
to the SOC. The first is to access the SOC through software.
The second is to attach status LEDs to the SOC for a visual assessment of status. As standard, each SOC card includes 16 low voltage
2-wire 24 Vdc digital outputs. LEDs are commonly attached to these
outputs in a location that is visually convenient.
In addition to the 16 low voltage 2-wire standard digital outputs,
another 32 low voltage 2-wire 24 Vdc digital outputs may be attached
to the SOC card with a separate optional component (sold separately).
SOC in a Pow-R-Command 100 System
When an SOC is installed into a Pow-R-Command 100 system, it is
given a unique address. This address allows it to be given information
from other controllers or programming tools such as software.
Because each USC in the system is individually addressed, the SOC
is able to send instructions to one or many USCs. The most common
instruction from an SOC to a USC is to switch Smart Breakers ON or
OFF based on the status of an input wired to the SOC. For additional
information on Pow-R-Command 100 networks, see Technical
Document TD01412014E.
The printed circuit board that the SOC attaches to is complete with
terminals for proper network connection. These two components are
sold separately.
FIGURE 3. PROGRAMMING/NETWORK PORT
Programming Switch Configuration
Each input into the SOC can be configured as one of many types
of inputs:
●
Demand accumulation (demand metering).
●
Timed momentary.
●
Timed maintained.
●
Maintained.
●
Momentary.
●
Alarm — provides warning indication.
●
Network — inputs are passed over the main network.
●
Local — inputs remain within the connected card module.
Switching Smart Breakers with an SOC
The SOC is designed to act as a means of coordinating inputs such as
wall switches. The SOC cannot operate Smart Breakers or relays.
To translate the commands from the SOC into switching actions on
Smart Breakers, the SOC must tell the USCs where the Smart Breakers
or relays are located. Since each USC has a unique address, the SOC
can target instructions to individual USCs and, more importantly, to
individual or group(s) of Smart Breakers or relays controlled by a USC.
SOC Applications
The SOC card can be mounted in two different ways. The first way is
to mount the SOC as integral to a Pow-R-Command 100 panelboard.
Each Pow-R-Command 100 panelboard can be manufactured with an
optional 7X Expansion Chassis integral to the panelboard chassis. The
7X Expansion Chassis comes complete with a printed circuit board
that contains the termination points for 48 low voltage 2-wire inputs
and a mounting location for an SOC card.

The SOC is purchased separately from the 7X Expansion Chassis and
can be mounted in the field or prior to shipment. For the purpose of
future expansion, a Pow-R-Command 100 panelboard can be ordered
with a 7X Expansion Chassis, but no SOC. When the need arises for
further inputs, the SOC can be field installed and commissioned.
Each control cabinet is a NEMAT 1 enclosure and comes complete
with a printed circuit board containing termination points for 48 low
voltage 2-wire inputs, a power supply, and termination points for network connections. The SOC is sold separately from the control cabinet.
The second application for an SOC is in a Pow-R-Command control
cabinet. When used in a control cabinet, the SOC can be mounted
separately from the panelboard, which may make connections to
inputs more efficient. The control cabinet is also an ideal way of
retrofitting the abilities of an SOC into a facility.
