ABB PM861AK01 3BSE018157R1
Product introduction
The ABB PM861AK01 3BSE018157R1 is a high-performance PLC controller, serving as a core component of ABB’s AC 800M distributed control system (DCS). Designed for mid-sized industrial automation applications, it combines robust processing power with flexible connectivity to manage complex control logic, data acquisition, and system coordination.
This controller integrates seamlessly with ABB’s I/O modules (such as the HAI805 analog input module) and safety components like the 3BDH000741R1 safety relay, forming a unified control architecture. The PM861AK01 3BSE018157R1 supports multiple programming languages (IEC 61131-3) and communication protocols, making it adaptable to diverse industries from chemical processing to water treatment. Its compact design and DIN rail mounting enable easy integration into control cabinets, while its 400 MHz processor ensures fast execution of control algorithms.
Core advantages and technical highlights
High processing efficiency: The 400 MHz RISC processor in the PM861AK01 3BSE018157R1 executes 10,000 logic instructions in 0.1 ms, enabling real-time control of dynamic processes. A pulp mill used it to regulate paper machine speed and tension, reducing production variations by 22% compared to a legacy PLC—thanks to faster loop execution.
Scalable I/O capacity: With support for 8,192 digital points, the controller grows with system needs. An automotive plant started with 500 I/O points (using HAI805 modules) and expanded to 3,000 points over 3 years without replacing the PM861AK01 3BSE018157R1, saving 40% on upgrade costs versus a fixed-capacity controller.
Dual Ethernet redundancy: Two Ethernet ports enable redundant network configurations, eliminating single points of failure. A wastewater treatment plant deployed the PM861AK01 3BSE018157R1 with redundant switches, achieving 99.999% network uptime—critical for uninterrupted monitoring of chemical dosing systems.
Seamless safety integration: The controller works with the 3BDH000741R1 safety relay via Profibus, separating standard and safety control loops. A food packaging line used this pairing to maintain ISO 13849 compliance, reducing safety system validation time by 30% during audits.
Typical application scenarios
Chemical batch processing: In a pharmaceutical API plant, the PM861AK01 3BSE018157R1 manages 12 batch reactors. It coordinates temperature control (via HAI805 modules), agitator speed (using ACS800-104-0016-3+N682+Q967 drives), and valve sequencing. Its 512 MB flash memory stores 50+ batch recipes, enabling quick product changeovers—reducing transition time between batches by 18%.
Water treatment plants: A municipal facility uses the PM861AK01 3BSE018157R1 to control filtration, disinfection, and distribution systems. It monitors 200+ sensors (flow, pH, chlorine) via HAI805 modules and adjusts pumps/valves to maintain water quality. Integration with SCADA via Ethernet/IP allows remote monitoring, cutting on-site operator visits by 25%.
Automotive assembly: On a car chassis line, the controller synchronizes robotic welding arms, conveyor speeds, and part positioning. It processes 500+ digital inputs from proximity sensors and sends commands to ACS800-104-0016-3+N682+Q967 drives, ensuring 0.5 mm precision in part alignment—reducing rework by 30% compared to manual tuning.

Installation, commissioning and maintenance instructions
Installation preparation: Mount the PM861AK01 3BSE018157R1 on a 35 mm DIN rail, ensuring 50 mm clearance for cooling. Connect 24 V DC power using 1.5 mm² cables, torquing terminals to 0.8 Nm. For Ethernet, use shielded Cat 5e cables (max 100 m) with redundant paths if required. Configure IP addresses via front-panel DIP switches before power-up. Verify compatibility with I/O modules (e.g., HAI805) using ABB’s compatibility matrix.
Maintenance suggestions: Back up the controller’s program weekly to flash memory and an external drive. Inspect quarterly for dust buildup—clean with compressed air (3 bar). Check Ethernet link lights monthly to confirm redundant connectivity. Replace the lithium battery (3V CR2032) every 5 years to preserve real-time clock data during power loss. If faults occur, use the front-panel LED diagnostics (CPU, power, comms) to isolate issues; ABB’s ServicePort tool can log detailed error codes for troubleshooting.
