ABB’s new Sentry Safety Relay increases capability of the Safety Relay

ABB Sentry Relays

ABB Sentry safety relays begin to blur the line between safety controllers and relays. Sentry safety relays are available for standard safety circuits, two-hand control, input and output expansion, timer-based circuits, and programmable universal safety relays capable of becoming any of the previously mentioned safety relay types.

Features and Benefits

  • Models with displays offer preset configurations and extensive fault information.
  • Multi-reset function enables reset of up to 10 Sentry safety relays using just one reset button.
  • Single Safety Relay (USR models) for all common safety applications helps reduce stock and saves warehouse space.
  • Multi-voltage models offer more flexibility and less stock.
  • Detachable terminal blocks speeds up connection and replacement.
  • Manual or automatic reset easily selectable by switch on the front of the safety relay for many models.
  • Extended temperature range of -25°C to +65 °C (old spec. -10°C to +65°C) and relative humidity range of 10% to 95% (old spec 25% to 95%). For SSR10, SSR20 and TSR20 models.
  • Small footprint (22.5mm wide)
  • Eliminate the need for intermediate control relays and enjoy high current capacity outputs
