RFBG-122-RK-24DC Functional Safety Relay

Product Description

The RFBG series safety relay's input terminals receive signals for emergency stops, protective gates, and safety light curtains—i.e., signals from devices with normally closed contacts used for emergency braking or to protect people entering hazardous areas—and are widely used in mechanical engineering and other industries.

Advantages

  • 1oo2 architecture.
  • Detection of short circuits on contacts.
  • Controlled manual reset.
  • The safety function remains operational even if components fail.
  • Correct operation of the safety relay is tested automatically during each on-off cycle.
