RELAY
The switching functions and the error monitoring system influence the state of
several relays inside of the Multi-Channel Controller. The RELAY connection
(Fig. 3-4,
18, item J) allows to utilize the relay contacts for switching pur-
poses. The relay contacts are potential-free (floating).

Note:
Pin 25 is used for supplying relays with a higher breaking capacity. The
supply contact is protected at 200 mA with a PTC element. The element
is self-resetting when switching the unit off or unplugging the RELAY
connector.
