Libratherm offers AC / DC Signal Convertor cum Isolator (Model: ISM-10), designed in 35 mm. DIN Rail compatible modules. These modules accepts AC/DC input signal and provides optically / galvanically isolated output in the form of (4-20)mA or (0-5)V or (0-10)V proportional to the input signal. 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 or to any other electronics in the process industry accepting such signals, without any signal loss or ground line interference. The ZERO and SPAN presets are accessible to the user for onsite calibration and matching.

These modules operate on 230 VAC or 110 VAC supply or 24VDC. The module with single input and multiple parallel outputs (Model ISM-10-X and ISM-12-X) can also be provided to meet the process control requirement requiring simultaneous change of 2 to 4 outputs proportional to the single input variation. These modules are rugged, reliable, field proven and economically priced.

New model ISM-12-2-X for two input and two/four output is also available for V to V, V to I, I to I or I to V conversion.

Libratherm offers these two models LCC-04 to convert the load cell input to equivalent 4-20 mA output. Both the models can accept either single or up to four load cells – internally looped for parallel connections to give resultant and proportional 4-20mA signal as the summation / average of all the connected load cells. Since (4-20)mA signal being less susceptible to electrical noise, it can be taken to the long distance over ordinary copper wires, which can be fed to the Digital Indicator, PLC, Computer or other host of interfacing devices in the control room.

The stable and sufficiently rated adjustable or fixed excitation voltage of 5 to 12VDC is generated internally to power the load cells. Internal ZERO and SPAN presets are available to tare the dead weight and also for onsite calibration of 4-20mA to improve the measurement range and resolution. The high input impendence instrumentation amplifier with ultra low drift gives stable output to maintain long term accuracy and stability of weight measurement in the batch weighing process industry. LCC-04 is available in IP65 field mount ABS enclosure and LCC-10 is available in DIN rail mount ABS enclosure. They operate on 230VAC +/-20% supply.
