ISO120 eight-channel isolated and PWS740 0 ~ 20mA current loop circuit diagram

Other Circuits
Eight-channel isolated as shown in Fig constituted by ISO120 and PWS740 0 ~ 20mA current loop circuit. FIG drawn only one channel, circuit 0 ~ 5V input voltage into a current o

utput generated by the VN2222 tube drive 0 ~ 20mA current to the load RL. Because the use of isolation amplifier ISO120 with isolated power supplies with PWS740, signals, power and ground to the output signal input signal, power and ground completely isolated, so excellent anti-jamming performance of the circuit.
