Analogue 4-20mA Radio Telemetry Input Card

Analogue Input Card – RDNET1000 Transmitter & Outstation

0-2V / 4-20mA analogue input card with on-board precision reference.

Pre-configured analogue input card that can accept either a 0-2V voltage or 0-20mA or 4-20mA input and convert it to the RDNET1000 protocol for transmission. Intended for use within the RDNET 1000 outstation the unit includes an on-board precision voltage reference and 0.1% precision resistor for current loops.

Analogue Telemetry Input Card

Optionally the unit can be supplied with an isolated DC/DC convertor to provide a loop voltage to the sensor of 12V or 24V dc.
