In the process control and automation field, often there is need of interfacing some signals generated by thermocouple, Pt-100, load cell, current, voltage transducers, and MODBUS ASCII to the process controllers, PLC, etc. Also need to fed one signal input to the multiple control device. To take care of common ground loop (Due to common 24V supply) of many sensors to single system and also avoid loading effect, isolation of these signal from one another is must. The model featured here provides optical and/or galvanic isolation between supply to input and output, and between input and output, maintaining the desired level of accuracy and linearity.
