1.3.3.4 Digital Input wiring
▶
Use a mechanical contactor (non-voltage type) as relay for the digital input (DI).
▶
The relay for DI must have sufficient on-off repeatability at 5V open voltage and 1 mA short circuit
current.
▶
The OPEN COLLECTOR for DI should have low ON state voltage (<2V) and low leakage current less than
100μA at OFF state.
