Description: Current to voltage converter module will be powered by 7-36V, current input range is 4-20mA/0-20mA, voltage output range is 0-3.3V/0-5V/0-10V. Usage: In the process of signal transmission, the voltage signal will be weaker with the increase of transmission distance. Current transmission can avoid the signal weakening. High accuracy: The current signal sampling resistor adopts high-precision color ring resistance, offers high accuracy, small temperature and high power. Adjustable: Zero and full range can be adjusted as your needs; the module is with high stability, good linearity, industrial grade. Reserve connection protection: It is designed with reverse connection protection, if wires connect reversely, it will protect the module from burning. Specification: Material: plastic Product detailed size: 42X25.2mm Instructions for use: 1. The module is wired as defined, and the power supply voltage is 7-36V (if the output is to 10V, the supply voltage must be greater than 12V) 2. After power-on, the D2 light should be on, otherwise check the line connection. The board is reversely protected, and the reverse connection does not burn. 3. When the current input is at the minimum value (0mA or 4mA), adjust the ZERO potentiometer to make the VOUT output the minimum value (0.0V or other voltage). 4. When the current input is at the maximum value (20mA), adjust the SPAN potentiometer to make the VOUT output the maximum value (3.3V or 5V or 10V. When the input is 4-20ma, the output can be as small as 2.5V) Package Includes:(4 Pack) 1 piece current to voltage module
