Analog Millivolt Signal Isolators 90-270VAC Supply

SIM Mini 1.0 modules are available which accept Analog miliVolt (mV) signals from field sensors, i.e. Current Shunts, Pressure sensors, etc. These modules Amplify the input signal and transmit suitable 0-10V/4-20mA output signal to the measuring systems without loss of accuracy. Isolation between I/P & O/P helps in elimination of measurement errors due to Ground Loops and also ensuring safety of measuring system.

The SIM Mini 1.0 modules operate from 90-270VAC power supply.
