SGZ-12 type isolators are dedicated for making a galvanic isolation between input measuring circuit and output circuit. The device needs 24V DC of power supply.
Input, output and supply circuits are mutually isolated. The using of separators allows to reduce the impact of interference and ground potential difference. It also helps to put together different types of signals (0÷5 mA, 0÷20 mA, 4÷20 mA, 0÷5V, 0÷10V, 1÷5V). User is allowed to correct zero point and measuring range, using two potentiometers mounted on the front panel of housing.
