ABB 3BSE026055R3 CI856 S100 I/O Software License

ABB CI856 S100 I/O Software License 3BSE026055R3

Product Introduction

The 3BSE026055R3 is the software license variant for the ABB CI856 hardware interface. This module fully manages S100 I/O communication for the AC 800M controller. It mounts onto the TP856 baseplate, which uses a ribbon connector to link with S100 I/O racks. Each connected rack holds up to 20 I/O boards. The processor unit powers it directly through the CEX-Bus. Therefore, you will not need any external 24V supply for the module itself.

Key Technical Specifications

The ABB CI856 operates as a dedicated master device on the S100 I/O protocol. It does not support line or module redundancy. However, it provides a useful hot swap functionality (highlighted in red). This feature lets you replace the unit without shutting down the whole system.

Additionally, the communication speed is fixed by the protocol. The module includes a code locking device (highlighted in red). This mechanism prevents you from mounting incompatible components. The CEX-Bus can support up to 12 units in total. For the CI856, the typical 24V consumption is only 120 mA. Moreover, it uses a 36-pin Miniribbon connector (highlighted in red) for the I/O bus.

Environment and Certifications

This ABB 3BSE026055R3 meets strict industrial standards. Its operating temperature ranges from 0 to +55 °C (+32 to +131 °F). Storage temperature goes from -40 to +70 °C (-40 to +158 °F). The module is G3 compliant (highlighted in red) to ISA 71.04, ensuring corrosion protection. It also carries a CE mark and follows RoHS directives for EU, UAE, and CN. The protection class is IP20 according to EN60529 and IEC 529.

Mechanical Dimensions and Mounting

Installing the CI856 is straightforward. You first attach the TP856 baseplate onto a standard DIN rail. Then, you click the module onto the baseplate. The ribbon cable connects to bus extender boards inside your S100 I/O racks. Finally, you can connect up to five racks to one ABB 3BSE026055R3 interface.

Here are the precise dimensions:

• Width: 59 mm (2.3 inches)

• Height: 185 mm (7.3 inches)

• Depth: 127.5 mm (5.0 inches)

• Weight: 700 grams (1.5 lbs) including the base

For comparison, the gross weight for shipping is about 0.9 kg with proper packaging.

How the CI856 Saves Your Investment

A major benefit is the ability to reuse existing field wiring from older ABB Master and Advant OCS systems. You do not need to re-terminate cables or replace sensors. Consequently, this reduces both downtime and material costs. The CI856 acts as a bridge between your new 800xA controller and legacy S100 I/O panels. Furthermore, the hot swap feature supports maintenance without a full plant stop. This makes the 3BSE026055R3 license a cost-effective upgrade path.

Frequently Asked Questions (FAQ)

1. Can I use the CI856 with a standard AC 800M controller?
Yes, the ABB CI856 works perfectly with any AC 800M controller that has a free CEX-Bus slot. The processor provides both communication and power through that same backplane connection.

2. How many S100 I/O boards can one CI856 support?
It supports up to five I/O racks, and each rack holds a maximum of 20 I/O boards. Therefore, one 3BSE026055R3 interface can handle up to 100 I/O boards in total.

3. Does the module require a separate 24V power supply?
No, you do not need an external power source. The processor unit powers the CI856 directly via the CEX-Bus connection. Its typical consumption is only 120 mA at 24V.

4. What is the purpose of the code locking device?
The code locking device prevents you from inserting incompatible modules into the same baseplate. This protects your system from accidental hardware mismatches. It is a mechanical keying feature.

5. Can I replace a faulty CI856 without shutting down the system?
Yes, the module supports hot swap functionality. Consequently, you can remove the old unit and insert a new ABB 3BSE026055R3 while the controller remains powered and running.
