I/O and Communication Module Installation
The 5 I/O modules and single communication module may be selected for installation on the ioPAC 8020 system; all
modules may be hot-swapped, allowing for convenient installation/removal at anytime.
Care should be taken before installing the modules:
1. I/O modules (RM-1050-T, RM-1602-T, RM-2600-T, RM-3802-T, and RM-3810-T) may be installed on the ioPAC 8020-C
system in any order. However, the 9th slot of the ioPAC 8020-9 series is reserved for future expansion, so I/O modules
may only be installed in slots 1 through 8.
2. If multiple kM-2430-T Ethernet communication modules are to be installed on the ioPAC 8020-C system, the
installation order must start from the 1st or the last slot and continue consecutively, either “upwards” (1,2,3...) or
“downwards” (9,8,7…). Also, The 1st and last slot must not be occupied at the same time.
