The ABB Bailey IMQRS22 is a high-speed Quick Response I/O Module, engineered to perform rapid data acquisition and output operations within ABB’s Symphony and INFI 90 control systems. This module is specifically designed to handle applications where low latency and deterministic I/O behavior are critical, such as in emergency shutdown systems, turbine control loops, or real-time process alarms.

With its capability to process digital I/O changes nearly instantaneously, the IMQRS22 plays a vital role in safety instrumented systems and high-speed interlocking operations. It ensures that field data is captured and acted upon with minimal delay, thereby safeguarding process stability and operational safety.
