Wide range of supply voltage, the output voltage to support multiple ranges Zero and the range can be adjusted High stability, good linearity, industrial grade Resistance of current signal sampling with high precision color ring resistance, high precision, small temperature drift, Instructions for use: 1. Module according to the wiring definition, supply voltage 7-36 V (if the output is 10 V, the supply voltage must be 12 V) 2 after-the D2 indicator should be otherwise check connection! Board with reverse protection, the back does not burn. 3. When the current input is (0mA or 4mA), adjust the potentiometer zero so that the VOUT output is minimum (0.0 V or other voltage) 4 when the current input is maximum (20 mA), adjust the range potentiometer so that the output of the VOUT is the maximum (3.3 V, 5 V or 10 V, the output can be as low as 2.5 V when the entrance is 4-20ma) colour: Photo Color Material: PC+ metal size: 4.2x2.5 cm / 1.65x0.98 inch Package Contents: 1*Current To Voltage Module Only the above package content, other products are not included.
