The AC1324 is a optional universal interface board which includes a 26-pin I/O connector and 26 I/O screw terminals. The 26-pin connector accepts the AC1315 or CAB-01 cables from a 3B series 3B01, 3B02 or 3B03 backplane and provides 26 screw terminals for interconnecting to any analog I/O subsystem, such as programmable controller. It can be mounted either at the back of the AC1330 rack-mount kit (standoffs are included and should be used) or in a snap track.
