RTD 4.20mA analog sensor signal conditioners allow industry standard RTD temperature sensors to be directly connected to PLC 4.20mA inputs and industrial IO modules. The 4.20mA transmitter connection is a standard format in industrial measurement and control systems. The 4.20mA signal allows the RTD temperature sensor measurement to be run much further than the direct connection of the RTD temperature sensor 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.
Simple PLC RTD temperature measurement The Robert Owen Inc. ROI-XMA 4-20mA sensor transmitter allows 4-20mA PLC inputs to be used for RTD temperature measurement. Robert Owen Inc. temperature transmitters offer temperature ranges as wide as -200 to 500 Deg C or as small as 0 to 32 Deg C, depending on the make and model. […]
