Frequently Asked Questions

What's the advantage of 3NO+1NC configuration?

3NO contacts for controlling multiple safety circuits (main contactor, brake, alarm). 1NC contact for safety monitoring/feedback. Provides flexibility for complex safety systems.

What coil voltages are available?

G7SA-3A1B available in: 12, 24, 110, 220VAC and 12, 24, 110, 220VDC. Select coil voltage matching your safety control circuit.

How do I verify forced guided contact operation?

Periodically test: energize relay, verify all NO closed and NC open. De-energize, verify all NO open and NC closed. Any deviation indicates contact welding or mechanical failure - replace immediately.

Can I use this for light curtain interfacing?

Yes, wire light curtain OSSD outputs to control relay coil. When light curtain blocked, relay de-energizes, stopping machine. For direct light curtain connection, use dedicated safety relay module.
