diy โมดูลสัญญาณแรงดันไฟฟ้า 0-5 v to 4-20 ma

Description: Voltage switch current module can convert 0-5V voltage signal into 4-20mA current signal. In the process of signal transmission circuit voltage signal will become weak with transmission distance increased, the transmission can be avoided using weak electric current signal. Power supply voltage: DC 12V~24V. Input voltsge signal: 0~5V. Output current: 4-20mA. Module size :5.5*2.5cm zero and span can be adiusted (potentiometer adjustment). with the isolated nature of the non-optically isolated. Quantity: 1 Pc Note: 1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! 2. Please allow 0.5-1cm measuring deviation due to manual measurement. 1 cm = 0.3937 " Package Included: 1PC*Voltage to Current Transmitter Signal Module
