Description

The panelboard digital electrical measuring device Shch20.1 is designed to measure current or voltage in DC circuits for operation as part of the technical means of nuclear power plants, as well as in other industries. The device can be used in a set with primary converters for measurement of non-electrical quantities, if the ranges of the output electrical signal of primary converters correspond to the ranges of the input signal of the devices.

The device provides the possibility of selecting the input signal measurement range, changing the reading range and the unit of measurement. Shch20.1 has the possibility to transfer information to computing devices via RS485 interface (Modbus RTU, original protocol).

The device is made in a metal case of shield mounting. The mounting structure is designed for installation in a 50 mm thick shield.

According to the order it is possible to install the device in a shield of other thickness. Safety class of the devices: 2,3,4 according to NP-001-2015.
