Sensor/Valve Assembly
The Sensor/Valve Assembly module differs from the standard module in that it does not have a
female cable connection, does not connect to a neighboring module, does not contain logic, and has a
unique wiring scheme on the male connection. This module may be simply described as a junction
box with connection to provide +VDC to the sensor and valve, sensor output to the PLC, and valve
input from the PLC. The male connection interface will be a cable with flying leads and have two
meter (2m) length. The jacket shall be stripped and conductors perforated. See the current
Sensor/Valve Assembly, E0006229, for reference.
