Description

The Shch02 device is designed to measure and convert current or voltage in DC electrical networks into output unified DC signals and transmit the measured values via RS485 serial digital interface. The possibility of information exchange via RS485 interface, availability of output analogue DC signals and discrete outputs allow to use the devices in automated systems of various purposes. The devices are used in power engineering and other areas of industry to control electrical parameters and have a continuous mode of operation. Shch02 is included in the State Register of measuring instruments of the Russian Federation No. 68258-17. Interverification interval is 10 years.
