RTD Transmitters

RTD Transmitters allow industry standard RTDs to be directly connected to PLC 4-20mA inputs and industrial IO modules. The 4-20mA RTD connection is a standard format in industrial measurement and control systems. The 4-20mA signal allows the RTD measurement to be run much further than the resistive connection of the RTD 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
