ABB Bailey IMQRS22 Infi 90 Quick Response Module

Description

The ABB Bailey IMQRS22 (Infi 90 Quick Response Module) is a high-speed, standalone controller designed for the Infi 90 and Symphony Plus systems. Unlike standard control modules that operate on slower cycle times for general process loops, the IMQRS22 is engineered for applications requiring extremely low latency and rapid execution, such as turbine control, surge protection, and high-speed electrical load shedding.

Specifications

• Part Number: IMQRS22
  
• Module Type: Quick Response Control Module.
  
• Microprocessor: 32-bit high-performance processor.
• Instruction Execution: Capable of sub-millisecond logic execution.
• Memory: * RAM: 512 kbytes for high-speed data manipulation.
• NVRAM: 128 kbytes for setpoint and configuration retention.
• Power Requirements: +5 VDC at 2.5 A (12.5 W typical).
• Communication: Interfaces via the Module Bus to Infi-Net (Cnet) or local I/O modules.
• Self-Diagnostics: Continuous hardware and firmware monitoring with "Error" and "Status" LEDs.

Features

• Deterministic Control: Provides a highly predictable and consistent execution environment, essential for protecting fast-moving mechanical assets.
  
• Standalone Capability: Can operate independently of the main Cnet network once configured, ensuring safety functions remain active even if network communication is lost.
• Flexible I/O Interface: Primarily pairs with high-speed analog and digital slave modules (like the IMASI23 or IMDSI22) to minimize the total loop response time.
• Advanced Logic Support: Supports complex control algorithms, including PID, function blocks, and boolean logic, specifically optimized for high-speed scanning.
• Redundancy Ready: Can be configured in a redundant pair (using an IMRPI01 Redundant Power Interface) to provide bumpless transfer and high system availability.
• Hot-Swappable: Designed for insertion or removal under power within a standard Harmony Rack without disrupting the operation of neighboring modules.
