Description

The Shch72 device is designed for measurement and conversion of current or voltage in DC electrical networks into output unified DC signals and transmission of measured values via serial digital interface RS485.
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. Shch72 is included in the State Register of SI of the Russian Federation No. 68258-17. Interverification interval is 10 years.
