4-20mA Thermistor signal conditioning allows industry standard Thermistors to be directly connected to PLC 4-20mA inputs and industrial IO modules. The 4-20mA Thermistor connection is a standard format in industrial measurement and control systems. The 4-20mA signal allows the Thermistor measurement to be run much further than the resistive connection of the Thermistor itself. 4-20mA signals can be run directly for thousands of feet, when using the correct cable and power supply. Many PLC inputs either standardly or optionally can be configured for 4-20mA, and it is not unusual to find spare inputs in an installation
4-20mA Thermistor Transmitters The Robert Owen Inc. ROI-XMA 4-20mA sensor transmitter allows PLC Thermistor Measurement. With ROI-XMA; you can use 10K NTC thermistors with standard industrial PLC’s and industrial I/O. The ROI-XMA series of loop powered thermistor transmitters. They convert a thermistors temperature related resistance change. Into a standard 4-20mA instrumentation signal. The ROI-10KXMA series […]

Example 4-20mA thermistor transmitter wiring diagram A Simple 4-20mA Transmitter Operation Description The 4-20mA transmitter can be looked at as a temperature controlled variable load. It is in series with the power supply and current measurement shunt resistance. The effect is similar to the transmitter acting like a potentiometer. One that will vary total load
