This plug in card permits the interface of 2 volt free contacts, open drain or open collector transistor devices to the RDNET1000 Outstation or Telemetry Transmitters.
The card features on-board data encoding and comes complete with a pre-assigned unique electronic serial number in line with the RDN1000 data protocol. There are also 2 x status LEDs that can be enabled using a link to reflect the input contact status. (Closed = LED ON). With the link removed the power consumption is reduced, making the card ideal for battery powered applications.
