About This Product

The RFD-DIN-IO US Telemetry Interface is an industrial wireless I/O module designed to provide remote monitoring, control and serial data communication over a 900MHz radio link. It combines isolated digital inputs and relay outputs with an isolated RS485/RS422 interface, allowing equipment at two locations to communicate without requiring a physical communication cable between them.

The US version operates in the 902–928MHz band and uses frequency-hopping spread-spectrum radio communication. Its DIN-rail enclosure makes it suitable for installation inside industrial control panels and automation systems.
