Basic Product Identification
Model & Article Number: Model PM864AK01, corresponding article number 3BSE018161R1.
Product Category: Processor unit (CPU module) belonging to ABB’s Classic System 800xA platform,
serving as the core control component of the AC 800M controller series.
Lifecycle Status: Marked as "Classic" (mature product), offering stable performance and standardized
compatibility for industrial control applications.
Core Functional Characteristics
Processing & Memory: Equipped with an MPC862 processor running at 96 MHz (higher clock
frequency than the PM861AK01), with 32 MB total memory and 23.522 MB RAM available for
applications—providing ample space for large-scale control programs. 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 full redundancy (CPU, CEX-Bus, communication interfaces, and S800
I/O), with a maximum switchover time of 10 ms in redundant configurations, ensuring uninterrupted
operation for mission-critical systems.
Communication Interfaces:
2 RJ45 Ethernet ports (IEEE 802.3, 10 Mbit/s) for Control Network connection, supporting MMS and
IAC protocols; recommended for use with a 100 Mbit/s switched Ethernet backbone for optimal
performance.
2 RJ45 serial ports: COM3 (RS-232C, 75–19200 baud, non-isolated, with full RTS-CTS support) for
general use, and COM4 (RS-232C, 9600 baud, optically isolated) dedicated to 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), adapting to complex control logic requirements.
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 real-time status monitoring, an INIT push button for
system reset, a CompactFlash interface for storage expansion, and a slide & lock mechanism for easy
DIN rail mounting/dismounting. Each base plate has a unique Ethernet address for hardware
identification.
Technical Specifications
Performance Metrics: Executes 1000 boolean operations in 0.15 ms (faster than the PM861AK01),
delivering high processing efficiency for time-sensitive control tasks. 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 287/487 mA,
typical/max power dissipation 6.9/11.4 W; includes a redundant power supply status input for dual-
power redundancy support.
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, ensuring
consistent timekeeping across distributed systems.
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), ensuring stable power supply for connected I/O modules.
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.), consistent with the PM861AK01 for standardized rack integration.
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, suitable for harsh industrial
environments.
Protection Class: IP20 (per EN 60529/IEC 529), designed for installation in control cabinets without
additional enclosures.
