This is the RFDesign DIN-IO Isolated Telemetry IO-Interface Bundle.

The RFD DIN-IO provides an easy to use Telemetry Input / Output with 2 Fully Isolated Digital Inputs and 2 Fully Isolated Clean contact output relays.

The device allows bi-directional telemetry and data communications between a pair of devices. Each device interfaces with a completely isolated RS485 / RS422 interface (depending on the user configuration). The isolated RS422 interface makes the RFD DIN Rail IO a great choice for us in noisy and industrial environments.

The DIN-IO operates in pairs, ordering in pairs are recommended.

The bundle includes:
