4-20mA measurement module

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.

Signal processing:16 bit A/D sampling

Overload capacity:1.2 times the measuring range can be accurately measured; The input has overload protection, and the input will not be damaged when overloaded by 3 times the range.

Isolation:Each current input and voltage input is not isolatedIsolation between power supply and communication interface output.
