Connecting Field Devices

Connecting Field Devices with Power Supply
Depending on the distance from the controller, field devices
can be supplied by the controller or need a separate
transformer, see Table 20 on page 12.
For fusing see section "Fusing Specifications" on page 9.
Example 1: Power Supply via Controller
 24 V actuator connected to an analog output module
 Less than 100 m away from the controller

Cabling Field Devices
Cable Routing
Route low-voltage signal and output cables separately from
mains cables.

Table 26 Min. distances to power mains cables
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).
Cable Shielding
~
 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 the cabinet end.
– The shield must not be terminated at the
CLLIONLC01.
