Basic Product Identification
Model & Article Number: Model PM861AK01, corresponding article number 3BSE018157R1.
Product Category: Processor unit (CPU module) belonging to ABB’s Classic System 800xA platform,
designed as the core control component of the AC 800M controller series.
Lifecycle Status: Marked as "Classic" (mature product), featuring standardized hardware and stable
performance for industrial control scenarios.
Core Functional Characteristics
Processing & Memory: Equipped with an MPC860 processor running at 48 MHz, with 16 MB total
memory and 7.155 MB RAM available for applications. It includes 2 MB Flash PROM for firmware
storage and a built-in 3.6 V lithium backup battery to preserve data during power-off.
Redundancy Support: Supports CPU redundancy (compatible with CEX-Bus, communication
interfaces, and S800 I/O), with a maximum switchover time of 10 ms in redundant configurations,
ensuring high system availability for mission-critical applications.
Communication Interfaces:
2 RJ45 Ethernet ports (IEEE 802.3, 10 Mbit/s) for Control Network connection, supporting MMS and
IAC protocols.
2 RJ45 serial ports: COM3 (RS-232C, 75–19200 baud, non-isolated, with RTS-CTS support) and COM4
(RS-232C, 9600 baud, optically isolated, for configuration tools).
Programming & Expansion: Configurable via 800xA Control Builder; supports 32 applications per
controller, 64 programs per application, 128 diagrams per application, and 32 tasks with 32 different
cycle times (minimum 1 ms per application program).
I/O Expansion Capability:
Non-redundant CPU: 1 electrical + 7 optical I/O clusters on ModuleBus, supporting up to 96 I/O
modules.
Redundant CPU: 0 electrical + 7 optical I/O clusters on ModuleBus, supporting up to 84 I/O modules.
ModuleBus scan rate adjustable from 0–100 ms (varies by number of I/O modules); CEX-Bus supports
12 communication modules and a maximum supply current of 2.4 A.
Practical Design: Features LED indicators for status monitoring, an INIT push button for reset, a
CompactFlash interface for storage expansion, and a slide & lock mechanism for DIN rail
mounting/dismounting. Each base plate has a unique Ethernet address for hardware identification.
Technical Specifications
Performance Metrics: Executes 1000 boolean operations in 0.23 ms; supports up to 3000 events per
OPC client, with data transmission speeds of 36–86 events/sec and 113–143 data messages/sec to the
OPC server.
Power Supply: Operates on 24 V DC (19.2–30 V DC); typical/max power consumption 250/430 mA,
typical/max power dissipation 6.0/10.3 W; includes a redundant power supply status input.
Clock & Synchronization: Integrates a real-time clock with 100 ppm stability (≈1 hour deviation per
year); supports 1 ms clock synchronization between AC 800M controllers via CNCP protocol.
Electrical Parameters: Rated isolation voltage 500 V AC; dielectric test voltage 50 V; ModuleBus supply
current max 1.0 A (24 V) and 1.5 A (5 V).
Mechanical Dimensions: Width 196 mm (7.3 in.), height 119 mm (4.7 in.), depth 135 mm (5.3 in.);
weight 1200 g (2.6 lbs.).
Environmental Adaptability
Temperature Range: Operating +5–+55 °C (+41–+131 °F); storage -40–+70 °C (-40–+158 °F);
temperature change rate ≤3 °C/min (per IEC/EN 61131-2).
Humidity & Altitude: 5–95% relative humidity (non-condensing); maximum operating altitude 2000 m
(per IEC/EN 61131-2).
Anti-Interference & Durability: Pollution degree 2 (per IEC/EN 61131-2); corrosion protection
compliant with ISA 71.04 G3; vibration resistance (10–50 Hz: 0.0375 mm amplitude; 50–150 Hz: 0.5 g
acceleration; 5–500 Hz: 0.2 g acceleration); emitted noise <55 dB.
Protection Class: IP20 (per EN 60529/IEC 529), suitable for installation in control cabinets without
additional enclosures.
