Description

The panel-mounted digital electrical measuring device Shch23.4 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: selection of input signal measuring range, change of reading range and unit name, information transfer to computing devices via RS485 interface (Modbus RTU, original protocol), programming of thresholds of discrete analogue DUT indication colour change, scale illumination. The device is made in a metal case of panel mounting. Safety class of the devices: 2, 3, 4 according to NP-001-2015.
