ITEM NAME:Voltage to Current Signal Transmitter 0-3.3/5/10/15V to 4-20mA Module C4R8 Voltage to Current Signal Transmitter 0-3.3/5/10/15V to 4-20mA Module C4R8 Voltage switch current module can convert 0-3.3V / 0-5V / 0-10V / 0-15V voltage signal into 4-20ma current signal; In the process of signal transmission circuit voltage signal will increase transmission distance becomes weak, the transmission can be avoided using weak electric current signal. Color:green Material:CCL power supply voltage range of DC 7V ~ 30V2, the input voltage signal 0 ~ 3.3V, 5V,10V, 15V. the output current 4-20ma. zero and span can be adjusted (potentiometer adjustment). with the isolated nature of the non-optically isolated. module size: 3.3cm * 2.5cm Package Contents : 1pcs x Voltage to Current Signal Transmitter 0-3.3/5/10/15V to 4-20mA Module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
