WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-to-24VAC. Failure to observe
polarity will result in damage to one or more of the boards. Expansion Boards must be wired in such a way that
power to both the expansion boards and the controller are always powered together. Loss of power to the
expansion board will cause the controller to become inoperative until power is restored to the expansion board.

Wiring Considerations
The expansion base boards must be connected to 24 VAC as shown in
the wiring diagram below. Please see Table #1 for correct VA require-
ments to use when sizing the transformer(s) used for powering the ex-
pansion base boards.
Also please note that when wiring the OE356 - 4 Binary Input Expan-
sion Board(s), its contacts must be wired as wet contacts (connected to
24 VAC) not dry contacts as used with the OE357 - 4 Relay Expansion
Boards . See Figures 7 and 8 for complete wiring details.
