ABB CI862 3BUA000037R1 TRIO I/O Module

ABB CI862 3BUA000037R1 TRIO Communication Interface Module

Product Introduction

The ABB CI862 (3BUA000037R1) acts as a master communication interface between TRIO/Genius I/O and the AC 800M controller. It fits into a CEX bus slot and scans I/O data from up to 30 remote blocks on a single LAN. You can also set the module for redundancy to improve system availability. Additionally, the unit delivers a dedicated port for a Hand Held Monitor, which helps operators troubleshoot locally.

Technical Specifications

ABB CI862 supports direct connection for one TRIO LAN. The module uses ABB’s TRIO/Genius I/O protocol and operates as a master on the network.

• Max units on CEX bus: 4

• Blocks per CI862: 30

• Total I/O points per AC 800M: 1000

• Redundancy: Module redundancy supported

• Line redundancy: No

• Hot swap: Yes

• Connectors: Phoenix (4-pin), DB9 male, DB9 female

• 24 V consumption (typical): 190 mA

The controller can hold up to four CI862 modules at the same time. Each module scans its own I/O blocks independently. This design helps you distribute field devices across multiple LANs for better performance.

Mechanical and Environmental Data

The ABB CI862 is built for industrial control cabinets. Its IP20 protection keeps internal parts safe from large objects.

• Temperature (operating): +5 to +55 °C (+41 to +131 °F)

• Temperature (storage): -40 to +70 °C (-40 to +158 °F)

• Relative humidity: 5 to 95 %, non-condensing

• Protection class: IP20 (EN60529, IEC 529)

• CE‑marking: Yes

• WEEE compliance: DIRECTIVE/2012/19/EU

Dimensions:

• Width: 59 mm (2.3 in.)

• Height: 185 mm (7.3 in.)

• Depth: 127.5 mm (5.0 in.)

This module weighs 700 g with its base. Its compact shape leaves room for other CEX modules in the same rack.

Installation Guidelines

First, insert the ABB CI862 into any free CEX slot on the AC 800M backplane. Next, connect the TRIO LAN cable to the 4-pin Phoenix or DB9 port. Then attach a Hand Held Monitor to the secondary port if needed.

For redundant setups, install two CI862 modules on the same backplane and configure them as a pair. The system automatically switches communication if the active module fails. Use shielded cables for the TRIO LAN to reduce electrical noise.

Remember to set the correct baud rate and block addresses in your engineering tool before powering up. The CI862 handles I/O scanning without extra programming for basic data exchange.

Frequently Asked Questions (FAQ)

1. Can I use the ABB CI862 with a non‑redundant AC 800M system?
Yes, the ABB CI862 works in both single and redundant controller setups. Redundancy for the module itself is optional.

2. How many TRIO blocks can one CI862 scan?
A single CI862 scans up to 30 TRIO/Genius I/O blocks on one LAN. Four modules give you up to 120 blocks in total.

3. Does the module support hot swapping?
Yes, you can replace a faulty ABB CI862 while the controller stays powered on. Always follow local safety rules before removing any hardware.

4. What happens if the TRIO LAN cable fails?
The CI862 reports a communication loss to the AC 800M. The controller can then trigger an alarm or switch to a redundant path if line redundancy is configured externally.

5. Is the CI862 still in active production?
The lifecycle status is “Classic,” meaning ABB no longer actively produces it. However, we stock genuine units and provide full support for existing installations.
