Field Devices
Depending on the distance from the controller, field devices can be supplied with power by the same
transformer used for the Panel Bus I/O Modules, or by a separate transformer, using cables as specified in
Table 22.

Routing Cables to Field Devices
Route low-voltage signal and output cables to field devices separately from mains cables.
Table 23. Minimum distances to power mains cables
Cable
Minimum Distance
shielded
0.4” (10 mm)
unshielded
4” (100 mm)
All low-voltage signal and output cables should be regarded as communication circuits in accordance with
VDE 0100 and VDE 0800 (or NEC or other equivalent).
• If the general guidelines for cable routing are observed, it is not necessary to shield field device signal and
power supply cables.
• If for whatever reason, the routing guidelines cannot be observed, the field device signal and power supply
cables must be shielded.
– Shielding of cables leading to field devices must be grounded only at one end.
– Do not connect the shield to the CIPer Model 50 controller.
