Characteristics
The PDM (Power Distribution Module) system possesses several notable characteristics.
Here is an expanded explanation of these characteristics:
Core Distribution System:
The PDM system is divided into two major categories, with the first being the core
distribution system.
The core distribution system consists of essential components that are responsible
for managing and distributing power within a cabinet or a series of cabinets.
These core pieces have the capability to connect to a PPDA (Power Distribution
Accessory) I/O pack, enabling system feedback and monitoring of power-related
data.
Branch Circuit Elements:
The second major category of the PDM system comprises the branch circuit
elements.
The branch circuit elements function to distribute the power output generated by the
core distribution system to individual circuits within the cabinets.
2/6
Unlike the core components, the branch circuits do not contribute to the PPDA
system feedback. Instead, they have their own set of feedback mechanisms or
monitoring systems in place.
Selective Utilization:
It is important to note that not all of the PDM's core components and branch circuits
are expected to be utilized in every system.
The specific configuration and utilization of the PDM system may vary based on the
specific requirements and power distribution needs of a given application or
installation.
System PDM Features
The Mark VIe control is intended to run on a flexible, modular array of power
sources. In many redundant combinations, the power distribution modules (PDM)
support 115/230 V ac, 24 and 125 V dc power sources. The applied power is
converted to 28 V dc to power the I/O packs.
The controllers can run on 28 V dc, direct ac, or direct 24 V dc battery power. The
PDM system is divided into two major categories: the core distribution system and
the branch circuit elements. The core pieces all have the capability of connecting to
a PPDA I/O pack for system feedback. They manage the primary power for a
cabinet or series of cabinets.
The branch circuit elements distribute the core output to individual circuits in the
cabinets. They do not contribute to the PPDA system feedback. Branch circuits
have their own set of feedback mechanisms. It is not expected that all of the PDM's
core components and branch circuits will be used on every system.
The power distribution capabilities of the Mark VIe system are designed to
accommodate a versatile range of power sources, offering flexibility to adapt to
various industrial setups. These power sources can be configured in different
combinations, including 24 V DC, 125 V DC, and 120/240 V AC sources, based on
the specific requirements of the application.
The Mark VIe power distribution hardware is carefully configured to suit the needs
of the system and the equipment it controls. Depending on the installation and
available power sources, the hardware may be tailored to utilize the necessary
power inputs while disregarding unused ones. This ensures efficient utilization of the
available resources while meeting the demands of the system.
One of the vital functions of the power distribution hardware is the conversion of
input power to a standardized 28 V DC. This 28 V DC supply serves as the primary
source of power for operating the control electronics within the Mark VIe system. By
converting the diverse input power into a uniform 28 V DC output, the system
achieves a consistent and stable power supply, promoting smooth and reliable
operation.

Furthermore, the Mark VIe system efficiently distributes the remaining power to fulfill
specific requirements, such as powering various Input/Output (I/O) signals. This
distribution process ensures that the appropriate power is allocated to the relevant
components, enabling seamless communication and functionality within the system.
Core Distribution
In the realm of Power Distribution Modules (PDM), the core distribution circuit
stands as a pivotal component responsible for the primary management of power
within a cabinet or a series of interconnected cabinets. It serves as the central hub
for controlling and regulating the power flow to various critical components and
devices within a system. Here, we delve into the intricate workings and features of
the core distribution circuit.
Power Sources and Input: At the heart of the core distribution circuit lies a
corresponding module or board that acts as the recipient of power from one or more
sources. This input typically comprises alternating current (AC) power, which forms
the basis for the subsequent power distribution process. The core distribution circuit
is equipped to accept power from multiple AC sources, ensuring redundancy and
reliability.
Control Electronics and Terminal Boards: One of the primary functions of the core
distribution circuit is to provide power to the control electronics within the system. To
achieve this, power is meticulously distributed to terminal boards, which serve as
intermediaries between the core circuit and the various electronic components.
These terminal boards play a critical role in routing power to the right destinations,
ensuring the smooth operation of control systems and devices.
Bulk Power Supplies: Integral to the core distribution circuit are the bulk power
supplies. These specialized power supplies are fundamental components within the
core PDM system. Their primary function is to convert the incoming AC power into a
stable and standardized 28-volt direct current (DC) power output. This output is vital
for powering a wide array of electronic components and devices, guaranteeing their
proper functionality.
Monitoring and Distribution: Within the core distribution circuit, one or more 28-volt
output boards are strategically positioned. These boards serve as vigilant overseers
of the 28-volt power distribution process. They monitor the power levels and ensure
that the precise amount of power required by each component is delivered
efficiently. This meticulous monitoring and distribution process minimize power
wastage and enhance the overall energy efficiency of the system.
Interconnectivity and Feedback: The core distribution circuit can also be
interconnected with other core boards within the system. This interconnection is
often facilitated by the use of ribbon cables, which link various core boards to the
one housing the Power and Data Acquisition (PPDA) Input/Output (I/O) pack. This
interconnected setup allows for seamless communication and coordination between
different components, further optimizing system performance.
4/6
Complete Monitoring and System Feedback: One remarkable feature that sets the
core distribution circuit apart from traditional power distribution methods is its
capacity for comprehensive monitoring and system feedback. Unlike conventional
systems, which may lack real-time insights into power utilization, the core PDM
system continuously monitors power levels, ensuring that each component receives
the necessary supply. This proactive approach to power management not only
enhances system reliability but also facilitates informed decision-making regarding
maintenance and upgrades.
Branch Circuits
Branch circuits play a crucial role in the overall power distribution within the
cabinets. These circuits are responsible for dividing the power output from the
Power Distribution Module (PDM) core into individual alternating current (AC) and
direct current (DC) circuits. The purpose of these branch circuits is to facilitate the
efficient and controlled distribution of power to various components and subsystems
within the system.
It is important to note that branch circuits are not directly connected to PPDA
Input/Output (I/O) pack, as their primary function is to provide power distribution
rather than system feedback. Their main focus is on efficiently distributing power,
ensuring that each component or subsystem receives the necessary power supply
for its operation.
One of the key aspects of branch circuits is the ability to provide power status
feedback signals to the control system. This feedback allows the control system to
monitor and assess the power status of individual elements or devices connected to
the branch circuits. By receiving these feedback signals, the control system can
detect any power-related issues or anomalies, enabling timely intervention or
troubleshooting.
In most cases, branch circuit elements are typically single circuit boards that handle
specific power distribution functions. These circuit boards are dedicated to individual
circuits within the system, ensuring precise control and management of power
distribution. By utilizing dedicated circuit boards, the system can effectively allocate
power to different components or subsystems, optimizing the overall performance
and reliability.
