ABB PM863 Controller – High-Integrity CPU for Reliable Industrial Automation

The ABB PM863 Controller is a powerful and reliable CPU unit designed for critical industrial automation and process control applications. As part of the trusted AC 800M controller series, the PM863 offers advanced performance with high availability and support for safety-certified systems.

The CPU board of the PM863 includes a high-speed microprocessor, RAM memory, a real-time clock, LED indicators, a CompactFlash interface for data storage, and an easy-to-use INIT push button. This combination ensures smooth operation and easy system management.

On the base plate, the PM863 features two RJ45 Ethernet ports (CN1 and CN2) for connecting to the Control Network. It also offers two serial communication ports (COM3 and COM4). The COM3 port is an RS-232C port with modem control signals, while COM4 is an isolated port designed for secure connection to configuration tools.

A major advantage of the ABB PM863 Controller is its CPU redundancy support, which enhances system availability by backing up the CPU, CEX-Bus, communication interfaces, and S800 I/O modules. This ensures that your industrial systems run smoothly, even during unexpected failures.

For high-integrity and safety-critical applications, the PM863 can be upgraded with the SM812 module and SIL-certified software. This upgrade allows non-critical control systems to meet SIL safety standards according to IEC 61508 and TÜV certification, without sacrificing business-critical process control capabilities.

Key Features of ABB PM863 Controller:

• High-performance CPU board with CompactFlash support

• Dual Ethernet ports and serial ports for flexible networking

• CPU redundancy for increased system reliability

• Easy integration with S800 I/O modules and communication expansion (CEX-Bus)

• Supports High-Integrity (HI) functions with SM812 module and SIL software

• Compliant with IEC 61508 and TÜV-certified for safe and reliable operation

• Ideal for upgrading standard control to SIL-certified safety control

The ABB PM863 is the perfect solution for industries seeking a combination of process control and functional safety in a single, efficient controller.
