STB PDT 3100 Source Power Wiring
Summary The STB PDT 3100 uses two two-pin source power connectors that let you connect
the PDM to one or two 24 VDC field power source(s). Source power for the sensor
bus is connected to the top connector, and source power for the actuator bus is
connected to the bottom connector. The choices of connector types and wire types
are described below, and a power wiring example is presented.
Connectors Use a set of either:
z Two STB XTS 1130 screw type field wiring connectors
z Two STB XTS 2130 spring clamp field wiring connectors
Both connector types are provided in kits of 10 connectors/kit.
These power wiring connectors each have two connection terminals, with a 5.08 mm
(0.2 in) pitch between pins.
Power Wire
Requirements
Individual connector terminals can accept one power wire in the range
1.29 ... 2.03 mm
2
(16 ... 12 AWG). When 1.29 mm
2
(16 AWG) power wire is used,
two wires can be connected to a terminal.
We recommend that you strip at least 10 mm from the wire jackets to make the
connections.
Safety Keying
Power
Wiring Pinout
The top connector receives 24 VDC source power for the sensor bus, and the
bottom connector receives 24 VDC source power for the actuator bus.
Note: The same screw type and spring clamp connectors are used to deliver power
to the STB PDT 3100 PDM and to the STB PDT 2100 PDM. To avoid accidentally
connecting VAC power to a VDC module or vice versa, Schneider offers an
optional STB XMP 7810 safety keying pin kit for the PDMs.
Refer the Advantys STB System Planning and Installation Guide (890 USE 171)
for a detailed discussion of keying strategies.
