High-Speed 4AI 3DI 4DO Control Card | ABB IMQRS22

Product Description

Dynamic High-Speed Process Control Interface

The IMQRS22 (Model: IMQRS22) is a specialized, high-performance Quick Response Module engineered for the ABB Bailey Infi 90 and Symphony Harmony Distributed Control Systems (DCS). Designed for applications where standard I/O processing speeds are insufficient, the IMQRS22 (Part Number: IMQRS22) provides ultra-low latency signal acquisition and execution. By integrating 4 Analog Inputs, 3 Digital Inputs, and 4 Digital Outputs on a single hardware platform, this module enables localized, rapid-action control loops. It is the primary choice for managing volatile process transients, such as turbine speed governing and surge protection, where reaction times must be measured in sub-milliseconds to ensure system stability.
