8.5
I/O Device Conduits
Rigid steel conduit should be used for wiring runs to all I/O devices,
especially runs over 50 feet (15.2 m). Each I/O module is equipped
with a single 1 to 1-1/4 inch (2.5 to 3.3 cm) knockout to accommodate
conduit for I/O device wiring. Additional knockouts are provided for
power and Petro-Net™ communication wiring conduits.
To prevent interference, all wiring to and from the VSmart Module must
be protected by rigid steel conduit. Probe and sensor wires must be
alone in their conduits. DO NOT run the wiring from other
manufacturers’ probes, sensors or alarms.
