The Auxiliary I/O Board (A4) contains six (6) configurable one (1) form-C relays. Relay contacts are rated for 0.5A @ 125 Vac/Vdc.

Each relay has:

  • a RED LED that serves as a debugging aid that illuminates when the relay is in alarmed state
  • a second contact set which feeds back the relay’s state to ATevo’s main processor

Each relay is configurable to:

  • change states based on any alarm condition or status point
  • be latching or non-latching
  • switch to active state after a pre-programmed delay
