PM856K01 ABB AC 800M CPU Module

Description

PM856K01 is a mid-range CPU module from ABB’s AC 800M series, part of the Compact Control Builder product line, designed for medium-scale automation control applications. As a cost-effective alternative to the PM866K01 model, it delivers reliable industrial-grade performance while maintaining a more budget-friendly profile. Its key ordering identifier is 3BSE018105R1, which may vary by version, and it falls under the AC 800M base controller category.

Equipped with a 32-bit RISC processor and 16MB expandable RAM, the module supports a maximum of 1024 I/O points, making it suitable for process control, machine automation, and SCADA system deployments. It features versatile communication interfaces including 2×RS232/RS485 ports and 1×10/100Mbps Ethernet port, enabling seamless integration with industrial networks. The module is programmed via the Control Builder M Professional environment, and operates reliably across a wide temperature range of -20 degrees Celsius to 60 degrees Celsius. It accepts a working voltage range of 24-230V, offers CE certification, and benefits from the AC 800M series’ modular, rail-mounted design, with support for redundant configurations and a broad range of I/O signals, including intrinsically safe signals for hazardous areas.
