Power Distribution Modules
The STB PDT p105 basic PDM (Power Distribution Modules) provide power for the
I/O module sensors and actuators (1) via the same bus 3.
Two basic power distribution modules are available:
b The STB PDT 3105 module is dedicated to providing power to I/O module sensors and
actuators requiring a c 24 V power supply.
b The STB PDT 2105 module is dedicated to providing power to I/O module sensors and
actuators requiring a a 115/230 V power supply.
Both models have 1 removable fuse.
The STB PDT p100 standard power distribution modules provide power separately
for the I/O module sensors and actuators (1) via the sensor bus 1 and the actuator
bus 2.
Two standard power distribution modules are available:
b The STB PDT 3100 module is dedicated to providing power to the I/O module sensors
and actuators requiring a c 24 V power supply.
b The STB PDT 2100 module is dedicated to providing power to the I/O module sensors
and actuators requiring a a 115/230 V power supply.
Both models have 2 removable fuses.
This configuration allows:
b disconnection of the I/O power supply while maintaining the power supply to the
NIM network interface module, and thus to the machine bus. For example: in a NIM
I
NTERBUS configuration.
b isolation of the output power from the inputs to increase immunity to
electromagnetic interference.
b power supply independent of the outputs allows connection of a Preventa
™
safety
module. If one of these outputs is disconnected, the inputs are still managed.
This configuration allows disconnection of the I/O power supply while maintaining
the power supply to the NIM network interface module, and thus to the machine bus.
For example: in a NIM I
NTERBUS configuration.
(1) One power distribution module can supply power to both digital and analog I/O modules
simultaneously.
