Converter 4-20mA to 0-10V 

During the transmission of circuit signals, voltage signals tend to weaken as the distance increases. To mitigate this signal degradation, current transmission is employed, offering enhanced resilience. This module specifically facilitates the termination of signal transmission in the form of current, subsequently converting the signal into a voltage signal for detection by a single-chip system. The current input is versatile, supporting both 4-20mA and 0-20mA, while the voltage output caters to a range of options including 0-3.3V, 0-5V, and 0-10V. The board's output voltage range can be conveniently configured to meet specific requirements through the adjustment of jumpers. This design ensures optimal signal integrity and adaptability in various applications.

Quick Spec

• Input Signal: 0-20mA or 4-20mA
• Output Range: 0-3.3V, 0-5V and 0-10V
• Power Input Range: 7-36V

Mode of Operations

• At the minimum input current (0 mA or 4 mA), turn the ZERO potentiometer to set the desired output voltage corresponding to the set zero current. Clockwise rotation increases output voltage.
• Voltage Ranges Options 0-3.3V, 0-5V and 0-10V (Set via Jumpers)
• When current output is at max (20mA), adjust span potentiometer to set Max Output Voltage
• At the minimum input current (0 mA or 4 mA), turn the ZERO potentiometer to set the desired output voltage corresponding to the set zero current. Clockwise rotation increases output voltage.
• At a maximum current of 20 mA, by rotating the variable resistance SPAN, the maximum value in the range determined by jumpers is selected. Clockwise rotation increases output voltage.
• It is not recommend setting 0 Volts with a minimum current of 4 mA, because in this case the microcontroller will not be able to determine if the cable to the sensor is broken or it really shows the minimum values.
• After power on, D2 indicator should be on, if not check wiring

Board Layout

Jumper Configuration

ON: jumper cap buckles on the two jumper pins - jumper shorted
OFF: two jumper pins without the jumper cap - jumper removed

To fine-tune the 4..20 mA current to voltage converter, you need to select the values ​​of two potentiometers: ZERO and SPAN, corresponding to the zero and maximum current values ​​at the input. Claim potentiometers with a wide step.
