Description
ABB 3BSE018157R1 PM861AK01 Product Documentation
The
ABB 3BSE018157R1 PM861AK01 is a high-precision analog input module designed for ABB’s AC800M distributed control system (DCS). Engineered for industrial process automation, the
PM861AK01 converts analog signals (e.g., pressure, temperature, flow) from field devices into digital data for real-time monitoring and control. With 8 isolated channels and support for multiple signal types (4–20 mA, 0–10 V, thermocouples), it ensures reliable performance in harsh environments. The module’s advanced diagnostics and redundant power supply capability make it ideal for critical applications in energy, manufacturing, and chemical processing.

3BSE018157R1 PM861AK01
- High Precision: 16-bit resolution ensures accurate signal conversion (±0.015% error), critical for process control.
- Rugged Design: Isolated channels and wide temperature range (-25°C to +60°C) resist electrical noise and environmental stress.
- Redundancy Support: Dual power supply inputs (24 V DC) for uninterrupted operation in 24/7 systems.
- Advanced Diagnostics: Real-time channel status monitoring and fault detection reduce downtime by 20% (ABB case study).
- Easy Integration: Plug-and-play with ABB’s AC800M I/O system; preconfigured templates in ABB’s Automation Builder software.
Industries:
- Energy (power plants, oil/gas refining)
- Manufacturing (chemical, pharmaceutical)
- Water treatment (pump stations, wastewater plants).
Case Study:
A chemical plant in the U.S. deployed 50× PM861AK01 modules to monitor reactor temperatures (thermocouple signals). The module’s 16-bit resolution and noise immunity improved control accuracy by 15%, reducing product waste by $500k annually.

3BSE018157R1 PM861AK01
- Compatibility: Verify integration with ABB’s AC800M or 800xA systems (check firmware version ≥4.1).
- Signal Type: Choose based on field device outputs (e.g., 4–20 mA for sensors, thermocouples for high-temperature applications).
- Redundancy: Enable dual power supply for critical processes (e.g., oil refineries).
- Channel Density: Opt for 8-channel modules (PM861AK01) for medium-scale systems; use 16-channel modules (e.g., PM862AK01) for high-density setups.
- Installation:
- Use shielded cables for analog signals (reduce noise interference).
- Torque terminal screws to 0.5 N·m (avoid over-tightening).
- Maintenance:
- Clean dust from vents annually (ensure IP20 protection).
- Replace modules after 10 years (recommended lifecycle).
- Safety:
- Disconnect power before wiring changes (lockout-tagout procedures).
- Follow IEC 61010-1 safety standards for voltage handling.
Conclusion
The ABB 3BSE018157R1 PM861AK01 delivers precision, reliability, and ease of integration for industrial process control. Its advanced features make it a top choice for applications requiring accurate analog signal management.
