The relay output can be used to disable external devices or
incorporated into your machine’s E-stop string (or other protective
circuitry) for fail-safe protection. The REC provides Form_C
(Normally Open) contacts to disable external equipment in the event
of a malfunction.
Important: Both the fault relay and the LED (Axis OK) are
activated during normal operation and deactivated during
a malfunction.
The fault output relay contacts are UL listed and CSA certified for 1A
at 30V DC. Figures 2.13 and 2.14 are examples of typical fault relays.
