PRODUCT INFORMATION
Product Overview
The ABB SPDSI22 DSI22 is a Digital Input Module for the Bailey INFI 90 distributed control system. This module features 16 discrete input channels designed for process automation monitoring. It accepts input voltages including 24 V DC, 48 V DC, 125 V DC, and 120 V AC. Hardware jumper configurations allow engineers to match channel voltage requirements directly on the card.
The unit installs in standard Harmony Rack I/O slots using backplane and DIN-rail mounting configurations. Its mechanical enclosure measures 358.14 mm by 269.24 mm by 73.66 mm for modular rack integration. Process facilities use this module to read field switch statuses across varying AC and DC voltage levels. Standard commercial operating range specifications ensure stable performance within process control environments.
