1) Wire connections multi-function input terminals,
terminals FWD and REV:
EV2000 multi-function input terminal uses a full-bridge
rectifying circuit as shown in Fig. 3-. PLC is the common
terminal of terminals X1~X8, FWD and REV. The current
flows through terminal PLC can be pulling current, and
also the feeding current.
and REV is flexible and the typical wiring is shown
below:
A) Method 1 of connections (Dry contacts)
①If internal 24V power supply is used, the wiring is
