Product Description

GD416K0 is an air rate of 16kbps high speed radio modem that provides reliable, real-time data communications with RS-485 interface.Users can install their data transmission systems easily and quickly with GD416K0 radio modems. By saving the cost of cables, it can actually result in huge savings compared to wiring devices with cables and wires the old-fashioned way.

It is used in setting up a simple, efficient radio networks such as SCADA & Telemetry for utility distributions, power distribution networks and transaction networks.
