RLY 1 to RLY 8 COM – N.O. Connections
These are the eight Normally Open relay contacts of the WCC III
V-Out Relay board (OE430-01). These are to be used for powering
of pilot duty relays.
No more than 24 VAC/VDC is to be switched by the Relays. There
is a load protection device called a varistor across each of the 8 relay
output connections of the WCC III V-Out Relay board that limit
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 32Volts, or current draws of more
than 1 amp per contact could and will result in damage to the WCC
III V-Out Relay board and/or to the SAT III controller.
A pre-made control output common jumper wire (PL100867) can
be used to connect all eight of the relay common connections of the
WCC III V-Out Relay Board together.
The WCC III V-Out Relay board (OE430-02) has eight relays with
individually selectable N.C./N.O. contacts on the OE430-02.
WCC III V-Out RELAY Board
Installation and Mounting
It is important to mount the WCC III V-Out RELAY board in
a location that is free from extreme high or low temperatures,
moisture, dust, and dirt.
Be careful not to damage any of the electronic components when
mounting the WCC III V-Out RELAY board. Remove the WCC
III V-Out RELAY board from its Snap-Track mount. Using the
Snap-Track as a template, mark the two mounting holes. Drill
pilot holes in the enclosure back panel, and secure the Snap-Track
using sheet metal screws. Do not allow metal shaving to fall onto
the WCC III V-Out RELAY circuit board. Reattach the WCC III
V-Out RELAY board into the Snap-Track.
