STC Series – Data/Signal Line Surge Protection Devices for Transient Data
Sola surge protection devices provide complete industrial
strength protection from transients at critical loads such as
control panel applications by incorporating a multi-stage
strategy. This approach involves clamping the initial highenergy impulse, filtering any remaining noise or transients
to the PLC or sensitive equipment and finally, protecting
the Data/Signal lines entering and leaving the control panel.
Modern, networked industrial facilities require error free
transmission of information for maximum productivity and
data integrity.
Sola Data/Signal Line surge suppression devices multi-stage
hybrid design to achieve quick response with high energy
absorption. These units are available in a variety of
application specific voltage levels and packaging configurations. The STC series is used to protect network signal lines
entering or leaving control panels including PLCs, universal
remote I/O, DeviceNetTM and Data Highway Plus.

The rapid development of automated controls, telecommunications and fire/security systems has made it imperative to
have properly coordinated low-voltage protection. Modern
networked industrial facilities require error free transmission
of information for maximum productivity and integrity of data.
The Sola STC series protects all susceptible low-voltage
cable routes entering a facility and at key points within the
building.

STC - PoE Series for Category 5 Power-over-Ethernet and Category 6 Applications
The Sola STC-PoE series is designed to work on Category
5 PoE transmission lines as well as Category 6 applications.
They feature both female to female and male to female
RJ-45 connection options for ease of installation.
Power-over-Ethernet is a technology for wired Ethernet
LANs (Local Area Networks) that allows the electrical
current to be carried by the data cables rather than power
cords. This minimizes the number of wires that must be
strung in order to install the network. The result is lower cost,
less downtime, easier maintenance and greater installation
flexibility than with traditional wiring.
Power-over-Ethernet (PoE) allows users to power devices
over Ethernet cabling. Power and networking is provided
over a single cable. PoE has tremendous advantages in
industrial applications. The ease of combining signal and
power in a single Ethernet cable connection is contributing
to the already rapid evolution of Ethernet-based industrial
control systems. Category 5e and Category 6 commonly
known as Cat5e and Cat6 are the most widely used Ethernet
connectivity methods on the market today. Cat5e and Cat6
are defined in ANSI/TIA/EIA 568-B standard for Unshielded
Twisted Pair Cabling.
The STC-PoE series is ideally suited to protect expensive
equipment and critical communication/data transfer from
internally generated transients and noise.

STC - DRS Series DIN Rail Protection
The Sola STC-DRS series is a DIN Rail mountable, single
pair surge suppression module implementing three-stage
hybrid technology. This module addresses over-voltage
transients with gas tubes and silicon avalanche components.
In addition, sneak currents are mitigated with resetable fuses
(PTCs). The PTC increases resistance by several orders of
magnitude when over currents exceed safe levels. A normal
state resumes when over currents are removed. The ability
to self-restore in this manner significantly increases suppressor performance and survivability.
The STC-DRS Series mounts onto a standard 35mm
industrial DIN rail. There are three Field Side and three
Electronics Side screw terminals. One is reserved for a
shield. Three electrically tied ground terminals are provided
for grounding the unit to building-approved ground. The
shield is isolated from ground.

STC - 642 Series, Data/Signal Line Protection
The STC-642 series of surge suppressors are dual pair (four
wire) modules using three-stage hybrid technology. This
module addresses over voltage transients with gas tubes
and silicon avalanche components. In addition, sneak and
fault currents are mitigated with resetable fuses (PTCs). The
PTCs increase resistance several orders of magnitude when
over currents exceed safe levels. A normal state resumes
when over currents are removed. The ability to self restore in
this manner significantly increases suppressor performance
and survivability.
The STC-642 card edge module is gold-plated, double
sided and is designed to mate with the STC-642 gold-plated
female terminal connector (sold separately). When snapped
together, the data circuits pass thru the protector in a serial
fashion from the four Field Side terminals to the four Electronics Side terminals. Terminals 1 or 10 of the PCB1B
must be attached to building approved ground.
