OPERATING ENVIRONMENT · MONITORING & CONTROL

Fail-safe relay isolation for higher-current ET 200S load circuits

◈ Operating environment

Install in an approved ET 200S station with the required terminal module.

Use the documented 24 V DC control supply and permitted load-voltage range.

Provide external circuit protection suitable for the connected load.

Commission only within the validated machine-safety architecture.

◎ Monitoring & control

One relay output provides two normally open safety contacts.

Green output-status indication supports direct operating checks.

Potential separation isolates the relay channel from the backplane bus.

Safety validation must confirm the controlling F-DO and complete shutdown path.
