Connecting 4-Wire Discrete Sensors and Actuators
Example A below shows the connection of a shielded 3-wire sensor. The sensor
signal is carried to the module point IN1. The sensor is supplied with power using
the module points U
and GND. The sensor is grounded with the FE (Functional
S
Earth Ground) module point.
Example B below shows the connection of a shielded actuator. By providing the
supply voltage U
, even actuators that require a separate 24V supply can be
S
connected directly to the module. The maximum current carrying capacity of the
output must not be exceeded.
