Relay Interface Module - Part # 4500.14

Relay Interface Module
Product Literature

The Relay Interface Module is a unique option used to compliment the Duplex II System. This flexible programmable I/O controller can be used to activate several different relays to signal events that are controlled by the microprocessor in the Duplex Model II. The module adds yet another level of safety to the emergency valve shutoff system by allowing the operator to respond to events or trigger functions automatically. Designed for simplicity and functionality, the Relay Interface Module gives you total control over the emergency valve shutoff system.

  • All relays can be activated based on ten specific diagnostic and system conditions
  • Integrates directly with Duplex II controller to make all five relays programmable
  • Circuit board contains snubber network to protect sensitive electronic circuits
  • Individual LED’s indicate activated relays
  • All three output relays are configured as DPDT rated at 115/230 VAC 5.0 amps.
  • Normally open and normally closed connections available
  • Can be set to momentary or latching relays
  • Relays plug in for easy replacement
