Signal Isolator

Libratherm Instruments AC / DC Signal Convertor cum Isolator (Model : ISM-10) is designed in 35 mm. DIN Rail compatible modules. These modules accepts DC input signal of (4-20)mA, (0-20)mA, (0-50)mA, (1-5)V, (0-5)V or (0-10)V or from the Thermocouple or RTD Sensors or from the load cell, pH, ORP, conductivity sensors etc.. It also accepts AC variable voltage of (0-110 V)/(0- 230 V) or AC current of (0-5)A or (0-1) A from external CT and provides optically isolated output in the form of (4-20)mA or (0-5)V or (0-10)V. Both the input and output levels have their grounds optically / galvanically isolated. Thus the process signals received from the Transducers or transmitters or Sensors can be directly connected through ISM-10 to the PLC, DCS, SCADA etc.. without any ground line interference. The ZERO and SPAN presets are accessible to the user for on site calibration. These modules operates on 230 VAC / 110 VAC or 24VDC supply. The module with single input and multiple parallel outputs can also be provided to meet the control system requirement. These modules are rugged, reliable, field proven and economically priced.
