Product Overview

The ABB IMRIO-02 expands the signal acquisition and control capabilities of the ABB Ability™ System 800xA and INFI 90® distributed control systems. This Remote I/O Module serves as a high-precision bridge for analog signals, providing two channels of analog input and two channels of analog output in a single, compact footprint. It enables engineers to digitize field variables like pressure and temperature while simultaneously driving actuators such as control valves or VFDs. Designed for decentralized control architectures, the IMRIO-02 minimizes field wiring costs by bringing the I/O interface closer to the process equipment without sacrificing signal integrity.

Engineering Advantages

Hybrid I/O Density: The IMRIO-02 combines both Input (AI) and Output (AO) functionality on a single card. This dual-purpose design allows for local closed-loop control at the remote rack level, significantly reducing the number of individual modules required for small-scale process skids.
Superior ±0.1% Precision: The 12-bit resolution and high accuracy rating ensure that delicate process variables remain stable. This precision prevents "signal hunting" in sensitive control valves, which extends the life of mechanical actuators in petrochemical and water treatment plants.
Galvanic Noise Rejection: Field-side electrical noise often corrupts analog data. The IMRIO-02 incorporates robust galvanic isolation and EMI shielding to drain electromagnetic interference, protecting the central processor from ground loops and transient voltage spikes.
Compact Remote Mounting: Its slim 1.0-inch width allows for installation in high-density remote cabinets where space is at a premium. This enables the decentralization of I/O, reducing long-run copper wiring and lowering installation labor costs.
Multi-Architecture Compatibility: The module bridges generations of ABB technology. It integrates natively with legacy INFI 90® racks while remaining fully compatible with modern ABB Ability™ System 800xA environments.
100% Brand New Assurance: We supply only factory-original, 100% new hardware manufactured in the USA. This ensures the 12-bit A/D converters and isolation barriers operate at peak efficiency for their entire service life, a critical factor for mission-critical automation.

FAQs

Q: Can I configure the IMRIO-02 for both voltage and current on the same module?

A: Yes. The IMRIO-02 supports both 0–10 V DC and 4–20 mA DC signals. You configure the specific signal type via the system software or hardware jumpers (depending on your rack configuration) to match your field device requirements.

Q: Does this module require an external power supply?

A: The IMRIO-02 draws its internal logic power from the ABB rack backplane. However, external 24 VDC loops for field transmitters typically require a separate field power supply wired through the termination unit.

Q: Is the IMRIO-02 hot-swappable?

A: Yes. The modular design allows for hot-swapping within the ABB rack. You can replace the module without powering down the system, though you should always follow standard safety procedures for your specific DCS environment.

Q: Where does the IMRIO-02 ship from?

A: These units ship directly from our facility in Webster, NY, USA, ensuring fast lead times and reliable handling for domestic and international industrial projects.
