Description:
In the process of signal transmission circuit, the voltage signal will increase with the transmission distance becomes weak, the use of current transmission can prevent the signal attenuation. This module is used for the end of the current signal transmission, the signal into a voltage signal for single-chip detection. Current input support 4-20Ma, 0-20mA, output voltage support 0-3.3V 0-5V 0-10V
Features:
Wide voltage range, the output voltage support multiple ranges
Zero and range can be adjusted
High stability, good linearity, industrial quality
Current signal sampling resistance with high precision color ring resistance, high precision, temperature drift small, high power
Instructions for use:
1. Module according to the definition of wiring, power supply voltage 7-36V (if the output to 10V, the power supply voltage must
be greater than 12V)
2. After power-up, the D2 indicator should be on, otherwise check the line connection. Board with reverse protection, reverse does
not burn.
3.when the current input is the minimum (0mA or 4mA), adjust the ZERO potentiometer so that the VOUT output is the minimum (0.0V
or other voltage) 4.when
the current input is at maximum (20mA), adjust the SPAN potentiometer so that the VOUT output is the maximum (3.3V or 5V or 10V,
the output can be as low as 2.5V when the input is 4-20ma)
According to your needs, through the jumper cap to select the correct range:
4-20ma: 0-2.5V range: J1 1.2 feet short, 3.4 feet shorted
0 - 3.3V range: J1 1.2 feet off, 3.4 feet off
0 - 5.0V range: J1 1.2 feet short, 3.4 feet shorted
0-10.0V range: J1 1.2 feet short, 3.4 feet off
0-20ma: 0-3.3V range: J1 1.2 feet short, 3.4 feet shorted
0 - 5.0V range: J1 1.2 feet short, 3.4 feet shorted
0-10.0V range: J1 1.2 feet short, 3.4 feet off
