The IMRIO22 remote input output slave module from ABB Bailey extends field I/O beyond the main control cabinet. Plant engineers deploy this module when process signals originate far from the central rack. Consequently, it shortens field wiring runs and reduces installation costs across large facilities.

Functional Overview
This module gathers field signals at a remote location and forwards them to the host controller. Therefore, it eliminates long individual cable runs back to the central cabinet. The IMRIO22 also receives output commands and drives local field devices directly. Meanwhile, its onboard energy storage protects communication buffers during brief power dips.
Installation and Handling Notes
Always confirm communication link settings before powering the IMRIO22 in a remote enclosure. In addition, verify grounding practices to prevent noise on the data link. Tighten all terminal screws to the specified torque value. Finally, test every channel during commissioning to confirm correct mapping.
