Description:
Relay Outputs: Each 8 Way Relay Board 302-676 is
fitted with eight relays (RL1 to 8) with 5A voltage free
contacts which can be used for control (e.g. releasing
doors) or monitoring (e.g. driving indicators, door open /
closed ) purposes.
The 302-672 Input / Output Board is then used to
provide the interface between the Slave CPU and this
board.
The Input / Output Board connects to the Slave CPU via
CN1. Dependant on configuration a maximum of 8 Input
/ Output Boards can be daisy chained together though
only three pre-positioned mounting areas have been
allocated within the FACP.
Installation:
Observe anti-static precautions at all times
1. Turn off the mains power and disconnect the
batteries.
2. Fit the 8 Way Relay Board and standoffs to the pre-
positioned holes in the left hand side of the
backpan.
3. Cable CN1 of the 8 Way Relay Board to CN4 or 5
of the I/O Board.
4. Install the 302-672 as per its Installation Guide.
5. Power up the FACP, connect the batteries.
6. Program the FACP and test.
