Input Board BRD25SIPB
Description
The Input Board makes provision for 16 voltage free contacts to be terminated to 16 optically
coupled inputs. Its application is primarily for the monitoring of controlled ancillary equipment or to
initiate an action / event due to a change of state from what is accepted as the norm.
Connectors
CN1
Is designated as the input Comms .
CN2
Is designated as the output Comms to the next board.
CN3
27 Volts into the Board. Quiescent Current:
2.6mA
CN4
27 Volts to the next Board unless it is the last board in the chain then it is left empty.
Terminal Blocks
TB 2 – 9
Taking note of the Common 0v terminals connect the voltage free contacts as shown
below
.
Note
: only the first 8 are functionally programmable in ZoneSense PLUS
SW1
There can only be 1 Input Board so the address on each board is set to 1.
LK1
Is the EOL Link and is inserted should the board be the last in the chain. If not
inserted on the last board the Main Card will initiate a communications fault.

#2. Select an appropriate length cable from those supplied to connect Comms & 27V.
Note: Only the first 8 Voltage Free Contacts are functionally programable.
The second 8 can be used to independently drive LEDs 8 to 16 on the
General Indicator Board.
