4 Digital Process meter


CM2-PR Process Meter has been designed in simple operation and 4 digital 20mm LED display with economic cost. They are can be programmed by buttons that are hidden in front panel. They are also available to option 2 relay output and an analog output or RS485(Modbus RTU Mode) communication.



 Measuring 0(1)~5V/0~10V, 0~10mA/0(4)~20mA

 Optional DC24V excitation power for 2 wire sensors

 The operation buttons are built-in to prevent users from arbitrary operation or incorrect setting, which may cause abnormal operation of the equipment

 The display value can be adjusted slightly with the "field measurement signal"

 The output can option relays and analog output or RS485 (Modbus RTU mode)

 Relay function in addition to start delay, active delay, delay off and active hold

 Analog output voltage signal range can be switched (0~10V/0~5V/1 ~5V) or current signal range can be switched (0~10mA/0~20mA/4~20mA)

 The analog output signal is free to set the corresponding display range (Span-50%) and can be fine-tuned on-site

 On board terminal design, no quality issue; installation depth is only 72mm



 2 wire sensing transducers as like as pressure, level and so on…

 Process alarm or communication for data collection
