TheABB IMCIS12is a Control I/O Slave module designed for theInfi 90 and Harmony distributed control systems. It functions as a versatile interface that allows a Master Controller to communicate with and control a variety of field signals, effectively expanding the system's processing capacity and localizing I/O management for enhanced process efficiency.
Specifications
Module Type: Microprocessor-based Control I/O Slave.
Slave Bus Interface: Communicates via the dedicated high-speed Slave Bus to interface with Master modules like the IMMFP12.
Onboard Memory: Includes 32 KB of EPROM for firmware and 8 KB of RAM for dynamic data buffering.
Microprocessor: Utilizes an 8-bit microcontroller to manage local logic and data packet sequencing.
Power Requirements: Operates on +5 VDC system power provided by the module mounting unit backplane.
Input/Output Capacity: Capable of managing multiple digital and analog points depending on the attached termination units.
Operating Environment: Temperature range of 0°C to 70°C with 5% to 95% non-condensing humidity.
Features
Distributed Processing: Offloads low-level I/O tasks from the Master Controller to improve overall system loop time.
Intelligent Self-Test: Performs continuous background diagnostics to verify the integrity of the RAM, ROM, and I/O circuitry.
Flexible Termination: Connects to a wide range of Bailey termination units (TU) via ribbon cables for diverse signal handling.
Hardware Interlocks: Supports fail-safe states for outputs in the event of a communication loss with the Master module.
Address Configuration: Easily configurable slave address via onboard dip switches for seamless network identification.
Diagnostic LEDs: Features a front-panel status display to indicate "Status" and "Error" conditions for rapid field troubleshooting.
