4 Wiring consideration
4.1 Wiring consideration for Input power terminal
4.1.1 When Built in DC24V power supply share Common terminal with External
power
Note: External DC2V + terminal can connect with the COM on the PLC, while – terminal must be
separated.
When external DC24V power supply share Common terminal:
Note: All external power DC24V + terminals can be connected with the COM, while – terminal
must be separated.
4.2 Wiring consideration for Input terminal:
Input ON/OFF duration must be following the principal to ensure the correctness of signals:
Ton>Δt + ton Toff<Δt + toff .
Input ON duration: Ton Module responding time for OFF—ON: ton
Input OFF duration: Toff Module responding time for OFOFF—ON: toff
PLC a scan time: Δt
Ton Toff
