Current 4-20mA to Voltage Converter 0-24V

In the process of circuit signal transmission in long cable, voltage drop and Electromagnetic interference are two major problems. Very long cables have resistance and that will cause a voltage drop. The voltage drop will degrade in signal accuracy. Current signal doesn’t have this problem as well as Current signals are immune to electromagnetic interference.

If a sensor is faulty or there is a broken wire, it can be easily identified. If the output is 0ma it will be difficult to identify whether it is a faulty signal or a good signal. This is why a 4ma scale is maintained fo error detection. As semiconductor devices requires 3mA current to operate, the standard has to be above 3mA.

The reason why 20ma is used as a maximum, is because the human heart can withstand up to 30 ma of current only. For safety reason 20 ma is chosen as maximum value. This is the main resion of Scaling of 4-20 ma.

This Module is used to convert current signal 4-20ma to 0-10vdc voltage Output (adjustable 24V MAX).

Quick Spec

  • Supply Voltage: 7 – 30 VDC
  • Input Current: 0/4mA – 20mA
  • Output Voltage: 0 – adjustable (24V MAX)
  • Temperature Drift: ±100ppm/°C
  • Dimensions: 40 x 20.5mm
  • Net Weight: 4g

Instructions

  • 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)
  • After power-up, the D2 indicator should be on, otherwise check the line connection. Board with reverse protection, reverse does not burn.
  • 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)
  • 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)
