Product Overview
When your industrial automation system demands reliable and high-performance control, the ABB PM858K01 MPC866 controller delivers. This CPU board integrates a microprocessor, RAM memory, a real-time clock, LED indicators, an INIT push button, and a CompactFlash interface. Designed for the ABB System 800xA platform, it supports CPU redundancy for higher availability, ensuring your operations stay online even in critical conditions.
Technical Specifications Breakdown
The PM858K01 is built on the MPC866 processor, operating at a clock frequency of 33 MHz. It provides 16 MB of memory, with 7.147 MB of RAM available for your application. The controller achieves a performance of 0.36 ms for 1000 boolean operations, making it suitable for fast logic processing. It includes 4 MB of flash PROM for firmware storage and a flash memory for general storage. Power supply is 24 V DC (19.2-30 V DC), with typical power consumption of 210 mA and maximum of 360 mA. Power dissipation is 5.1 W typical, up to 8.6 W max. The built-in backup battery is a lithium 3.6 V cell.
Industry Applications
In process control environments, the PM858K01 excels at managing complex automation tasks. Its support for up to 32 applications per controller and 64 programs per application allows flexible configuration for batch processing or continuous manufacturing. The controller's redundant CPU capability and dual Ethernet ports (IEEE 802.3, 10 Mbit/s, RJ-45) ensure minimal downtime in critical applications like oil and gas, chemical processing, or power generation. The real-time clock stability of 100 ppm (approx. 1 h/year) supports precise time-stamping for event logging.
Installation & Setup Guidance
Mount the PM858K01 on a standard DIN rail using the slide & lock mechanism for simple attachment and detachment. The base plate (TP830) provides two RJ45 Ethernet ports (CN1, CN2) for Control Network connection and two RJ45 serial ports (COM3, COM4). COM3 is an RS-232C port with modem control signals, while COM4 is isolated for configuration tool connection. Ensure the controller is used with System 800xA 6.0.2 and Compact Control Builder 6.0.0-1 or later. The unit has IP20 protection class per EN 60529, suitable for enclosure-free installation in industrial environments.
Maintenance & Reliability
To maximize uptime, inspect the PM858K01 periodically for dust accumulation and ensure proper ventilation. The controller's modular design allows step-by-step expansion without disrupting existing operations. Its ISA Secure certification and full EMC compliance (EN 61000-6-4, EN 61000-6-2) provide robust protection against electrical noise. The operating temperature range is +5 to +55 °C, with storage from -40 to +70 °C. Corrosion protection meets G3 per ISA 71.04, making it suitable for harsh industrial settings.
Compatibility & Integration
The PM858K01 integrates seamlessly with the ABB System 800xA ecosystem. It supports Control Network protocol MMS and IAC, and recommends a 100 Mbit/s switched Ethernet backbone. The controller can manage up to 12 communication modules on the CEX bus, with a maximum supply current of 2.4 A. For I/O expansion, it supports up to 96 I/O modules on the Modulebus with a non-redundant CPU, or 84 with redundant CPU. The modulebus scan rate ranges from 0 to 100 ms. It also supports PROFIBUS DP via compatible modules.
Selection Guide & Purchasing Advice
Before ordering the PM858K01, verify your system compatibility with System 800xA version 6.0.2 or later. The controller does not include redundancy by default (article number 3BSE082895R1), but supports redundant configurations with additional hardware. SpareTechPLC offers this ABB PM858K01 controller with fast shipping and expert support to help you select the right components for your automation upgrade.
