(3) Wiring example of 4-Wire sensor/transmitter (Voltage/Current input)
- In case of voltage/current input, wiring is same. Adjust the voltage/current setting switch
according to the case.
(a) Input resistance of current input circuit is 250 Ω (typ.).
(b) Input resistance of voltage input circuit is 1 MΩ (min.).
(c) Enable the necessary channel only.
(d) Analog input module doesn’t support power for input device. Use the external
