Product Description

The GDSC20 is a medium power SCADA radio modem which can be used to link SCADA devices such as PLC`s. The radio modems securely deliver serial data transparently in adverse industrial environments.

Simple SCADA systems are easily constructed with PLC and RTU devices by connecting their RS232 or RS485 serial port to the SCADA radio modem. GDSC20 can be widely used in oil, gas, booster station and other aspects of detection and control systems. Radio modem is an ideal equipment for SCADA systems now and in the future.Medium Power Radio Modem
