I/O Cards

The I/O card provides a rugged interface for up to 24 digital inputs and up to 16
changeover outputs for the connection of pushbuttons, loop detectors and above
ground detectors, or to provide a free-standing UTC Interface or for linking between
controllers.
A sub-equipped variant of this card is also available, fitted with only 4 changeover
outputs. If the IC4 Configuration requires the 24 in / 4 out variant but one is not
available, then a 24 in / 16 out card can be fitted in its place.
The I/O card connects to the CPU Card or previous I/O card via the GSPI interface
cable through which the card also obtains its power supply.
The first three I/O cards may be fitted in the primary cabinet. Additional I/O cards
may be fitted in an adjacent expansion cabinet.

the card should be replaced. Do not replace the fuse as the card will
have been damaged and must be replaced.
