Description
ABB CI535V26 3BSE022161R1 Product Description
Product Overview
ABB CI535V26 3BSE022161R1 is an ABB Advant OCS communication interface / RTU protocol module designed for remote communication and telecontrol applications. ABB’s product documentation identifies the exact part number 3BSE022161R1 with the type designation CI535V26 and the catalog description “RTU protocol IEC870-5-101 Unbal.”
The module is associated with the ABB Advant Controller 450 / Advant OCS environment and provides support for the IEC 870-5-101 unbalanced transmission protocol, a protocol widely used for telecontrol, remote terminal unit (RTU), substation and power-distribution communication.

ABB’s product detail specifically confirms IEC870-5-101 Unbalanced as the function of this part, and the Advant Controller 450 product guide lists CI535V26 / 3BSE022161R1 under the Telecontrol and SPA Bus options.
Important Specification Note
Some reseller pages incorrectly describe this unit as a generic Ethernet/IP, Modbus or power module and publish unrelated voltage/current specifications. Those claims conflict with the ABB-specific product documentation. For CI535V26 3BSE022161R1, the most reliable identification is RTU protocol IEC 870-5-101 Unbalanced communication module.
Main Features and Advantages
IEC 870-5-101 Communication
The primary function of CI535V26 is support for IEC 870-5-101, allowing an ABB Advant control system to communicate with compatible remote terminal units and telecontrol equipment. This makes it particularly suitable for electrical-utility and remote-monitoring applications.
CI535V26
Unbalanced Transmission Mode
The module specifically supports the unbalanced mode of IEC 870-5-101. This communication method is useful for master/RTU architectures in which the controlling station manages communication with remote stations.
Telecontrol Integration
ABB documentation places CI535V26 within the Telecontrol and SPA Bus section of the Advant Controller 450 platform. It therefore provides an interface between the plant control system and external telecontrol/RTU infrastructure.
Remote Data Acquisition
The module can support communication of remote status, measurements and control information between field/remote equipment and the central ABB automation system. This is valuable for geographically distributed electrical equipment.
Legacy ABB System Compatibility
3BSE022161R1 is an important identification number for maintaining older ABB Advant installations. The CI535 family includes several protocol-specific variants, so the complete part number should be matched when sourcing a replacement.
Application Fields
Power Substations
The CI535V26 is particularly suitable for electrical substations, where IEC 870-5-101 is used for remote monitoring and control. It can provide communication between the ABB control system and RTUs or telecontrol equipment.
Power Distribution Networks
In electrical-distribution applications, the module can transmit measurements, alarms, breaker status and control commands between remote substations and a central control system.
Power Generation
The module can be used in legacy ABB automation architectures for generator and plant auxiliary monitoring, particularly where remote equipment must exchange data with the plant control system.
Oil & Gas and Process Plants
Where ABB Advant systems incorporate remote equipment or utility substations, CI535V26 can provide a standardized telecontrol communication interface for collecting remote status and measurement information.
Industrial Remote Monitoring
The module is suitable for distributed industrial installations where remote devices need to communicate with an ABB supervisory/control system using IEC 870-5-101.
