4-20mA PT1000 transmitter signal conditioning allows industry standard PT1000 RTDs to be directly connected to PLC 4-20mA inputs and industrial IO modules. The 4-20mA PT1000 transmitter connection is a standard format in industrial measurement and control systems. The 4-20mA signal allows the PT1000 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.
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. […]
