Smart IO Relay Card

The Smart IO card provides 8 digital and 8 user programmable relays plus 1 communications good relays. The Smart IO card is typically used as an interface between a network containing Tension Sensor Wire Node1 network controller, Druid 25 LCD or Druid 28 LCD energizer, and third-party systems, but is a general input-output device. The Smart IO card can also be configured to control a Druid Network IO Card 8+1.

Networking with Druid Energizers and Smart cards


  • 8 digital inputs
  • 8 plus 1 programmable relay outputs (8 user relays + 1 valid comms relay)
  • Robust surge protection is included on all inputs and outputs
  • All relays can be individually configured to be independent dry contacts or common-ground wet contacts with 12V nominal output
  • Each relay has a very useful LED indicator to show if the relay is energized
  • 3 communications debug LED indicators for TX, RX and VALID COMMAND
  • 1 power-on LED indicator
  • In addition to the input states, the IO card also reports back temperature and supply voltage level
  • Removable connectors to ease replacement
  • Designed to mount into a Nemtek battery-backed power pack
