ABB XO08R2 1SBP260109R1001 is a high-performance relay output expansion module, designed as a companion component for the ABB Advant Controller 31 (AC31) series programmable logic controllers (PLC). Its core function is to expand the digital output capacity of the PLC system, converting control commands from the controller into on/off actions for field actuators. It provides reliable switching control for external actuators such as solenoid valves, contactors, indicator lamps, and small pumps/valves. As a key component for achieving control logic expansion + field device interlocking in industrial automation systems, it is widely used in machinery manufacturing, building automation, process control, and various other industrial fields due to its flexible configuration and high reliability.
1. Basic Parameters
The module features a standardized industrial modular design that balances compatibility, practicality, and reliability. With well-defined key parameters, it can be precisely matched with the ABB Advant Controller 31 series PLC for seamless integration and flexible expansion. Specific parameters are as follows:
Model Identification: Core model XO08R2, complete order / material number 1SBP260109R1001. It can be directly used for spare part matching, expansion, and replacement in ABB Advant Controller 31 series PLC systems without major modifications to the existing system.
Product Type: Relay output expansion module. It is not an independent control unit, but a dedicated expansion module deeply adapted for the Advant Controller 31 series PLC. It communicates at high speed with the PLC main controller via the backplane bus to ensure accurate transmission of control commands.
Output Specifications: Equipped with 8 independent relay output channels in a hybrid configuration — 4 normally open (NO) relay outputs suitable for 250V AC/2A loads; 4 configurable NO/NC relay outputs suitable for 250V AC/3A loads. It can be flexibly adjusted according to on-site control requirements and directly drive small and medium-sized actuators without additional intermediate relays.
Power Supply: Powered by an external 24VDC power supply, complying with industrial standard power requirements. It can be directly connected to the existing industrial control cabinet power system with high stability, effectively reducing the impact of power failures on module operation.
Electrical Isolation: Effective isolation between relay contacts and the control system improves anti-interference performance and operational safety, effectively resisting on-site electromagnetic interference and preventing malfunctions caused by signal crosstalk.
Environmental Adaptability: Operating temperature range -25°C to +60°C, protection class IP20. Suitable for harsh industrial environments including temperature extremes and dust, with stable operation without additional protection devices. The protection class can be upgraded for more demanding applications.
Mounting and Dimensions: Supports standard 35 mm DIN-rail mounting for easy and efficient installation in all standard industrial control cabinets. Compact dimensions (approx. 90 mm × 75 mm × 58 mm), weight approx. 0.26 kg – 0.49 kg, saving cabinet space and facilitating system integration.
Service Life: Uses high-quality relays and electronic components with strong mechanical stability, supporting long-term frequent operation and effectively reducing maintenance frequency and cost.
2. Structural and Functional Features
(1) Mechanical Design
The module has a compact industrial modular enclosure made of high‑quality industrial‑grade plastic, providing good mechanical protection and anti‑interference performance. It effectively resists dust and minor vibration in industrial environments, extending service life.The terminal blocks feature a anti-loosening design to ensure secure and reliable wiring, avoiding equipment failures caused by vibration-induced loose connections. Clear status indicators visually display the operating status of each output channel, allowing on-site engineers to quickly troubleshoot faults. The module supports hot swapping (under specific system conditions), enabling maintenance without shutting down the entire control system, greatly improving operational efficiency and reducing downtime losses.
(2) Core Functions
Flexible Output Expansion: Its main function is to expand the digital output channels of the ABB Advant Controller 31 series PLC, solving insufficient output points. Modules can be added flexibly based on system requirements without replacing the main controller, significantly reducing system upgrade and expansion costs for industrial control systems of various scales.
Seamless System Integration: As a native expansion module for the Advant Controller 31 series, it is fully compatible with CPUs and other I/O modules in the series. High-speed communication with the main controller via the backplane bus ensures fast, delay‑free response to control commands and accurate execution of logic, achieving true “plug and play” and simplifying system setup and integration.
Versatile Load Compatibility: The 8 hybrid relay output channels support external actuators of different power ratings. It can drive small indicator lamps and alarms, as well as directly control solenoid valves, small contactors, and miniature pumps/valves, reducing the need for extra intermediate relays or drivers, simplifying wiring, and lowering overall costs.
Intelligent Fault Diagnostics: Built-in self-diagnostic functions continuously monitor module and output channel status. Abnormalities such as poor contact or overload trigger fast fault feedback. Together with status indicators, engineers can quickly locate faults without complex procedures, greatly improving maintenance efficiency and reducing costs.
High Reliability and Anti-Interference: Optimized circuit design and high-quality components deliver strong electromagnetic compatibility, ensuring stable operation in harsh electromagnetic environments near motors and inverters. Relay contacts use premium materials with excellent resistance to welding and good conductivity, ideal for frequent switching and long-term reliable performance.
Easy Installation and Maintenance: Standard DIN‑rail mounting enables quick and simple installation and efficient integration with other control system components. Routine maintenance only requires periodic inspection of contact status and dust cleaning. The modular design allows fast replacement, further reducing maintenance difficulty and time.
3. Application Areas
With flexible output configuration, seamless system compatibility, and high reliability, this module is widely used in machinery manufacturing, building automation, process control, municipal engineering, and other industrial fields, mainly for PLC system output expansion to achieve precise control of various field actuators. Typical applications include:
General Machinery Manufacturing: Used in automated equipment such as machine tools, packaging machines, printing machinery, and assembly lines for controlling fixture actuation, conveyor start/stop, and limit switch signal output. Its multiple outputs and variable load capacity flexibly meet diverse mechanical control requirements, improving automation and efficiency. In automated packaging machines, it reliably controls frequent conveyor motor starts and stops, performing continuously under 3000 operations per day.
Building Automation: Applied in building lighting and HVAC (heating, ventilation, air conditioning) systems to control fans, pumps, motorized valves, and other actuators. Integrated with the central controller, it enables intelligent management and energy-saving control. In smart building air conditioning systems, it controls cooling tower fans based on timers and temperature signals, achieving energy savings while ensuring stable system operation.
Process Control: Used in production processes for food & beverage, pharmaceutical, chemical, and other industries to control solenoid valves, heaters, coolers, conveyors, and other actuators on production lines. It supports precise control of material handling, mixing, filling, packaging, and other processes, with high reliability effectively ensuring product quality and production safety.
Municipal Engineering: Deployed in automation systems for wastewater treatment plants and waterworks to control pump stations, valves, mixers, etc. It operates stably in humid and dusty environments, guaranteeing continuous and safe water treatment. It also supports municipal lighting, traffic signals, and other infrastructure, improving intelligent operation and maintenance.
