In the process of circuit signal transmission, the voltage signal will weaken with the increase of the transmission distance, and the current transmission can avoid the weakening of the signal. This module is used for the end of current signal transmission, the signal is converted into voltage signal for SCM detection. The current input supports 4-20mA and 0-20mA, and the voltage output supports 0-3.3V 0-5V 0-10V.

Features:

• The power supply voltage range is wide, and the output voltage supports multiple ranges
• Auto adjustment of zero and full range
• High stability, good linearity, industrial grade
• The sampling resistor of current signal adopts a high precision color ring resistor, which has high precision, small temperature drift and high power

Instructions:

• The module is connected according to the definition, the supply voltage is 7-36V (if the output is to 10V, the supply voltage must be greater than 12V)
• After power is on, the D2 light should be bright, otherwise please check the line connection. The board is equipped with reverse connection protection so that the board doesn’t burn.
• When the input current is minimum (0mA or 4mA), adjust the ZERO potentiometer, so that the output of VOUT is minimum (0.0V or other voltage)
• When the input current is the maximum (20mA), adjust the SPAN potentiometer, so that the VOUT output is the maximum value (3.3V or 5V or 10V, when the input is 4-20mA, the minimum output can be 2.5V)
