WCC III Binary Output Board /
V-Out Board Sequence
There are two versions of the WCC III V-Out Binary Output Board
– one that has 8 fi xed N.O. Relay outputs (OE430-01) and one that
has an individual output jumper selectable option for N.O. or N.C.
relay outputs (OE430-02). There are two modes of operation for
the WCC3 V-Out Relay Board – one is the V-Out mode and the
other is the Binary Output mode. These relay contacts are rated
for 1 Amp at 24 VAC/VDC operation. This WCC3 V-Out Relay
Board connects to the HSS expansion port on the side of the SAT
III Controller. The WCC3 V-Out Relay Board is an expansion
board that allows for another 8 binary outputs (relay contacts) to be
used with the SAT III Controller. Up to three of these WCC3 V-Out
Relay boards may be connected to the SAT III HSS expansion
port. Two boards in the Binary Output mode are supported and
one board in the V-Out mode is supported. One HSS WCC3 V-Out
board (OE430-01) will add 10 VA of VA load while the WCC3
V-Out board (OE430-02) will add 20 VA load to the SAT III power
requirement plus the loads that are connected to the 8 relay outputs
of the WCC3 V-Out Relay board.
V-Out Mode Note: These 8 Analog Input connections must
be connected to the 8 Analog Outputs of the SAT III Controller
in the V-Out mode of operation. These analog values are not
digitally transmitted via the HSS port on the SAT III to the
WCC3 V-Out Relay board in the V-Out mode.
There is a load protection device called a varistor across each of
the 8 relay output connections of the WCC3 V-Out Relay Board
that limits the allowable voltage to no more than 32 volts AC/DC
maximum at 1 amp current draw for each relay output contact.
Attempting to switch any voltage greater than 32 volts or current
draws of more than 1 amp per contact could and will result in
damage to the WCC3 V-Out Relay Board and/or to the SAT III
Controller.
The connecting HSS cable is available in 1 ft., 1½ ft., 3 ft., 25 ft.,
40 ft., 80 ft., and 120 ft. lengths. No more than 150 ft. of total wire
can be used to power a SAT III HSS loop.
