Wide range of supply voltage, output voltage supports multiple ranges Adjustable zero point and range High stability, good linearity, industrial grade High-precision color ring resistance for current signal sampling, high precision, small temperature drift, high power User Manual: 1. Connect the module according to the wiring definition, supply voltage 7-36V (if the output is 10V, the supply voltage must be 12V) 2. The D2 indicator should light up, check the connection! The board has reverse protection, so it won't burn out. 3. When the current input is at its minimum (0mA or 4mA), adjust the zero potentiometer so that the VOUT output is at its minimum (0.0V or other voltage) 4. When the current input is at its maximum (20mA), adjust the range potentiometer so that the VOUT output is at its maximum (3.3V, 5V, or 10V; the output can be as low as 2.5V when the input is 4-20mA) Color: Photo Color Material: PC + Metal Size: 4.2x2.5 cm / 1.65x0.98 inches Package Contents: 1 * Current To Voltage Module Only the above package content is included; other products are not.
