Single-channel control with feedback circuit (Fig. 18)
• Suitable for increase in capacity or number of contacts by means of
contactors or relays with positive-guided contacts.
•
S
= feedback circuit:
If the feedback circuit is not required, establish a bridge.
Dual-channel control with feedback circuit (Fig. 19)
• Suitable for increase in capacity or number of contacts by means of
contactors or relays with positive-guided contacts.
•
S
= feedback circuit:
If the feedback circuit is not required, establish a bridge.

Differential control with feedback circuit (see Fig. 20)
• Suitable for increase in capacity or number of contacts by means of
contactors or relays with positive-guided contacts.
•
S
= feedback circuit:
If the feedback circuit is not required, establish a bridge. If the
enabling circuit of the controller must be equipped with its own
feedback circuit, this circuit must be integrated as shown in the
wiring example "dual-channel control with feedback circuit"
(see there).
