Description:In the process of circuit signal transmission, the voltage signal will increase with the transmission distance becomes weak, the use of current transmission can avoid the signal weakening. 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, voltage output support 0-3.3V 0-5V 0-10V Features:Wide supply voltage range, the output voltage to support multiple rangesZero and range can be adjustedHigh stability, good linearity, industrial gradeCurrent signal sampling resistor with high precision color ring resistance, high precision, temperature drift small, high powerInstructions for use:1. Module according to the definition of wiring, power supply voltage 7-36V (if the output to 10V, the 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 appropriate range:4--20ma: 0-2.5V range: J1 1,2 feet short, 3,4 feet shorted0 - 3.3V range: J1 1,2 feet off, 3,4 feet off0 - 5.0V range: J1 1,2 feet short, 3,4 feet shorted0--10.0V range: J1 1,2 feet short, 3,4 feet off0--20ma: 0--3.3V range: J1 1,2 feet short, 3,4 feet shorted0 - 5.0V range: J1 1,2 feet short, 3,4 feet shorted0--10.0V range: J1 1,2 feet short, 3,4 feet offSize: 4.2x2.5cm/1.65x0.98inchQuantity: 1 Pc Note:Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bidDue to the difference between different monitors, the picture may not reflect the actual color of the item.
