INT-03 Safety Monitor Relay

The INT-03-024, INT-03-120, or INT-03-230 Safety Monitor Relay is intended for use as a part of a safety circuit in guard interlock applications. It is a safety relay which uses positive-guided relays, configured for self-checking, to inhibit machine start-up in the event of an internal component failure.

Both normally-open and normally-closed inputs are required. Multiple N.O. contacts can be wired in series while multiple N.C. contacts can be wired in parallel. Upon failure of either the N.O. or N.C. contact, the relay will turn off and prevent restart.

The INT-03 relay can also monitor contacts on external relays for controlling expansion block relays (Sentrol INT-05 and INT-06).
