The SAFE-SIL relay is used to couple safe output signals from DCS or PLC systems and can also serve as a contact expansion module for a basic safety device. It works with single-channel operation and automatic start, without requiring a feedback loop.
Function
- 3 NO safety relay contacts.
- 1 NC safe feedback contact.
- Safe extension module for safety control systems.
- Coupling of safe output signals from DCS or PLC systems.
