JM1-XXThe analog measurement module can measure a single channel/Multiple 4-20mA current input signals can be widely used in various industrial control and measurement systems. It can measure pressure, temperature, electricity, and other transmitter outputs～20mA (0-10mA) signal. Its output is in 485 bus mode, which can be hung on the same 485 bus as other manufacturers' control modules for easy computer programming. The communication protocol adopts Modbus protocol. Its functions and technical indicators are as follows:

lInput signal

Input:1/4/8 Route 4～20mA（0-10mA current, input signal is DC.
