STB PDT 3105 Source Power Wiring
Summary The STB PDT 3105 uses a two-pin source power connector that let you connect the
PDM to a 24 VDC field power source. The choices of connector types and wire types
are described below, and a power wiring example is presented.
Connectors Use either:
z an STB XTS 1130 screw type field wiring connector
z an STB XTS 2130 spring clamp field wiring connector
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 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 3105 PDM and to the STB PDT 2100 and STB PDT 2105 PDMs.
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.
