INSULATION AMPLIFIERS - SP 20, SP 25, SP 50, SP 52

Isolation amplifiers are devices serving for the transmission of the measured signal from the power circuits of voltage to 1000Vef into control circuits, while both systems are galvanically separated. The transducers can be used wherever it is necessary to transform the unified voltage or current signal to unified current or voltage signal. In the case of current measuring, it is necessary to prefix the by-pass, in the case of voltage measuring, it is necessary to prefix the voltage divider. The transducers are manufactured with fixed predetermined conversion.

TEMPERATURE MEASURING CONTROL - ST 101, ST 102, ST 201

The transducers are designed for the conversion of resistance signal from the temperature sensor PT100 or KTY. Output signal is in the range 0(4)-20mA or 0-10V according the type.

Input limiting temperatures of the transducers can be adjust according the requirements in the range from -200°C to +800°C (depending from the temperature sensor possibilities) with minimal temperature scale ranging 50°C. Switching power supply galvanically separated from the input and output is used in the transducers. The units are placed in the E1 cases, therefore enabling mounting on DIN rail.
