G9SR

Features

Compact safety relay unit family

G9SR family modules operate standalone and as a system with input and output extension. All modules are simple to set up using DIP-switches and provide clear diagnosis via LEDs on the front.

  • Three modules for all safety relay unit applications
  • Solid-state outputs for long life and high current safety relay outputs
  • Detailed LED indications enable easy diagnosis
  • Safe on- and off-delay function up to PLe
  • Up to PLe according to EN ISO 13949-1 and SIL 3 according to EN 61508
