The Relay8 a RS232 or UPB driven 8 circuit relay module



For control applications demanding isolated, dry contacts.

The Relay8net responds to the same simple 3 byte command as it's irrigation brother, the Rain8net and assigned any one of 250 possible addresses.

Possible commands include:
  • Turn on or off each relay individually
  • Turn off all relays on a specific module
  • Turn off all relays on all modules
  • Get the current status of all relays
  • Optional momentary mode from 1 second to 250 minute


Relay Specifications

  • Each of the 8 independent relays is equipped with a form C contact that is brought out to two plug in, detachable terminal strips.
  • 1A @24VDC resistive
  • 1A @120VAC resistive
  • Relay contacts are designed for low current applications as well as power switching.
