Product Description

The GDSC35 is GrandComm`s advanced high power SCADA radio modem with output power of 25 watts. It offers wide area coverage for remote control, telemetry and SCADA applications. It is designed for both point-to-multipoint and point-to-point networks and offers an up to 19.2 kbps over-the-air data rate.

GDSC35 supports RS-232 or RS-485 serial interface port. Build industrial wireless data links between RTUs, PLCs, controllers and sensors without cable over distances of up over 50 kilometers or over highly obstructed shorter links. Apart from its high output power, its high receiver sensitivity enables exceptional signal recovery.
