I/O Signal Port - CN1

CN1 connector is a 16-pin spring loaded connector.

Selection of I/O signal cable

To ensure I/O signal to not be affected by electromagnetic interference, a shielded twisted pair cable is recommended for this application.

Wire diameter ≥ 0.14mm2, foil shielded should be connected to PE terminal.
Wire length should be as short as possible, not more than 3m.
Install a surge suppressor in feedback circuit; flyback diode inversely connected in parallel in DC coil and capacitor connected in parallel in AC coil.
Recommended wire gauge: 24 - 26AWG
I/O signal included DI, DO and relay output signal
Please keep 30cm away from main power supply cable or motor power cable to avoid electromagnetic interference.
