Isolators / multipliers type SGT-12 are dedicated for providing galvanic isolation between controlled system (ex. transmitter, encoder) and main unit (regulator, indicator, data logger). Standard input signal (0÷5 mA, 0÷20 mA, 4÷20 mA, 0÷5V, 0÷10V, 1÷5V) after galvanic isolation can be converted into 4-20 mA output signal in two isolated current loops. Current output signal can also be processed into voltage signal with standard load resistance. The using of isolators/multipliers allows to reduce the impact of interference and ground potential difference. It also helps to match standard input signals to passive two-wire 4-20 mA outputs.
User is allowed to correct zero point and measuring range, using two potentiometers: ”Zero” and „Range”, mounted on the front panel of housing.
