The Input / Output Board is connected to the slave CPU via CN1
and acts as the interface between the
Slave CPU, 8 Way Relay Board and the 16 Way Opto Input Board.
Dependant on the panel configuration a maximum of 8 Input / Output boards can be daisy chained
together.

6.2 8 Way Relay Board 302 – 6760 / 1
Relay Outputs: Each 8 Way Relay Board 302-676 is fitted with either eight 1A, RL1 to 8, (302-6760) or
5A, RL9 to 16, (302-6761) relays with voltage free contacts which can be used for control ( eg. releasing
doors ) or monitoring ( eg. driving indicators, door open / closed ) purposes.
