Digital device for AC frequency measurement ShchCh120

The ShchCh120 device is designed to measure and convert AC frequency in single-phase electrical networks and other AC circuits into output unified DC signals and transfer the measured values via RS485 serial digital interface (Modbus RTU protocol).
The device is used in power engineering and other industrial areas for control of electrical parameters. The possibility of information exchange via RS485 interface, availability of output analogue DC signals and discrete outputs allow to use the device in automated systems of various purposes.
ShCH120 is included in the State Register of Measuring Devices of the Russian Federation No. 67465-17. Interverification interval is 10 years.
