This module accepts current input in the range of 4 to 20mA from any transmitter and produces proportional voltage output. This output can be connected as input to any ADC module. There are two independent current input channels in this module. The current received from any transmitter is processed using built-in instrumentation amplifiers. Essentially this is an add-on circuit to instrumentation amplifier module. This module requires external power supply ±12V DC @ 250mA.
