WCC III V-Out Relay Board
Connection Points (SS5008)
All external WCC III V-Out RELAY Board connection points are
single-tab ¼-inch Sta-Con connectors. With the exception of the
HSS EXP COMM port which is a 6-pin pre-made MOLEX type
mini-fi t cable connection.
VIN1 to VIN8 Connection
These analog inputs are set up as 0 to +15 DC Volts inputs. They
should be connected to and mated up with the SAT III controller’s
8 Analog Outputs. These eight inputs are only used for the V-Out
mode of operation, and are not needed for the Binary Output mode
of operation.
GND Connection
This is an analog ground common connection point for VIN1 to
VIN8 analog inputs. It is important that this “analog” ground on
the WCC III V-Out RELAY board is connected to the Analog Input
ground of the SAT III controller.
HSS Connectors
This is a 6-pin Mini-fi t connector that provides power and
communications to the WCC III V-Out RELAY board from the
SAT III controller. It is called an HSS port. The WCC III V-Out
RELAY board requires 24 VAC and ground connections which
are connected into these connector terminals. The WCC III
V-Out RELAY board is generally powered by the same 24 VAC
transformer that powers the satellite controller. Communications
to the SAT III controller is also in this cable, along with a shield
wire. The 6-pin HSS cable connections can also be daisy chained to
other WCC III V-Out RELAY boards and WCC III Binary Inputs
with Time Delay boards.
