What Is the ABB CI862?
When integrating remote I/O into an ABB AC 800M controller, the CI862 provides a reliable communication interface. This module connects TRIO/Genius I/O as native I/O, supporting direct connection for one TRIO LAN and a port for the Hand Held Monitor. As a master device, it manages channel data and I/O scanning for up to 30 TRIO blocks on a single LAN.
Technical Specifications Breakdown
- Max units on CEX bus: 4 – The AC 800M supports up to four CI862 modules, enabling flexible system expansion.
- 24 V consumption typ: 190 mA – Low power draw reduces energy costs and heat generation.
- Temperature, Operating: +5 to +55 °C (+41 to +131 °F) – Suitable for typical industrial environments.
- Temperature, Storage: -40 to +70 °C (-40 to +158 °F) – Withstands harsh storage conditions.
- Protection class: IP20 according to EN60529, IEC 529 – Basic protection for indoor use.
- Dimensions: 59 mm width, 185 mm height, 127.5 mm depth – Compact footprint saves panel space.
- Weight: 700 g (1.5 lbs) – Lightweight for easy handling during installation.
Industry Applications
In process control and manufacturing, the CI862 simplifies wiring by using TRIO remote I/O blocks. For example, in a chemical plant, you can place I/O blocks near field sensors and actuators, reducing cable runs. The module supports hot swap, so you can replace a faulty block without shutting down the entire system. This minimizes downtime and improves overall equipment effectiveness (OEE).
Installation & Setup Guidance
Mount the CI862 on a DIN rail in the control cabinet. Connect the 24 VDC supply (190 mA typical) to the Phoenix 4-pin connector. Use the DB9 female port for the TRIO LAN and the DB9 male for the Hand Held Monitor. Configure the module as a master on the CEX bus. Verify that the operating temperature stays within +5 to +55 °C. Ensure proper grounding and follow standard EMC practices.
Maintenance & Reliability
From a maintenance engineer's perspective, the CI862 offers high reliability with module redundancy and hot swap capability. Regularly inspect the module for dust buildup, especially in environments with high relative humidity (5 to 95%, non-condensing). Check the status LEDs (if available) for communication errors. Since the module supports hot swap, you can replace it without powering down the controller, reducing service time.
Compatibility & Integration
The CI862 works exclusively with ABB AC 800M controllers via the CEX bus. It communicates using ABB's TRIO/Genius I/O protocol. The module supports up to four units per controller, each managing up to 30 TRIO blocks. It does not require a HI Controller. For redundant systems, you can configure two CI862 modules for fault-tolerant operation.
Selection Guide & Purchasing Advice
Before ordering, verify that your AC 800M controller has an available CEX bus slot. The CI862 (article number 3BUA000037R1) is a classic lifecycle product. Please confirm current availability and lifecycle status with SpareTechPLC before purchasing. We stock this module and can advise on compatible TRIO blocks and accessories.
