The SAFE-DELAY safety relay combines immediate safety outputs with adjustable time-off delayed contacts. It is suitable for emergency stop buttons, safety door switches, and light curtain monitoring where controlled delayed shutdown is required.
Function
- 2 NO non-delayed safety contacts.
- 2 NO off-delay safety contacts adjustable up to 30 seconds.
- 1-channel or 2-channel input with automatic or manual start.
- Monitoring up to SIL 3 and Category 4, PL e.
