SAFE-SIL Coupling Relay and Contact Expansion

Description

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.
