Description
The RAI02 Redundant Analog Input module processes up to 16 high-level, group isolated, analog input field signals. Each channel is independently configurable for either 4 to 20 mA or 1 to +5 VDC ranges. FC 221 (I/O Device Definition) sets AI module operating parameters and each input channel is configured using FC 222 (Analog Input Channel) to set individual input channel parameters such as engineering units, High/Low alarm limits, etc.
A/D resolution of each channel is configurable from 12 to 16 bits with polarity. The RAI02 module has one A/D converter for all 16 input channels. The module will update 16 input channels in 100 msecs.
In current mode, the RAI02 module supports HART v5.4 instruments and provides short circuit protection by limiting current to a maximum of 96 mA. The RAI02 module will also detect an open circuit in less than 5 seconds.

- Robust environmental compliance
- Comprehensive EMC and safety certifications
The RAI02J supports up to 16 independently configurable analog input channels, allowing connection of transmitters, flow meters, pressure sensors, level instruments, and other process measurement devices. Each channel can be configured for either 4–20 mA or 1–5 VDC input signals and supports HART® v5.4 communication, enabling access to secondary device variables and diagnostic information.
The module incorporates redundant architecture, galvanic isolation, high-resolution analog-to-digital conversion, and continuous signal monitoring. Its design supports reliable process data acquisition while maintaining system availability in critical control applications. The RAI02J integrates directly with ABB Symphony Plus controllers and SD Series I/O subsystems, providing high-speed signal updates and accurate measurement performance.
The RAI02J ABB Redundant Analog Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The RAI02J delivers exceptional measurement precision with 12- to 16-bit configurable A/D resolution (including polarity) and an outstanding accuracy of ±0.1% of full scale. All 16 channels are scanned and updated within 100 milliseconds, ensuring real-time responsiveness for fast-acting control loops. In current input mode, the module fully supports HART v5.4 protocol communication, enabling access to up to 24 secondary digital variables (maximum 4 per channel) for advanced device diagnostics and asset management—critical for predictive maintenance strategies in modern process plants.
Designed with robust group isolation architecture, the module provides 1,500 V isolation between field wiring and internal logic circuits, effectively protecting sensitive control electronics from ground loops, common-mode voltages, and transient disturbances. Each channel features comprehensive protection including short-circuit current limiting to 96 mA and open-circuit detection in under 5 seconds, safeguarding both the module and connected field devices while providing immediate fault notification to the control system.

Power Down: Disconnect or lock out the cabinet power lines before handling components.Align: Match the alignment tracks on the rear of the 27 mm wide RAI02 module housing with the target slots on the fixed MTU.Seat: Press firmly until the module completely engages into the backplane connectors and the retention clips click into place.Check Status: Restore power and monitor the front plate LEDs. The R (Run) light should stabilize, and F (Fault) should remain unlit
Technical notes
