The ABB PM857K02 (3BSE088386R1) is a high-performance CPU module with CPU redundancy for high integrity applications. It has a clock rate of 96MHz, is capable of handling 1,000 Boolean operations at 0.17ms, and has 32 megabytes of memory, of which 22.184 megabytes of RAM are available for applications. Designed to connect to the control network, this module is equipped with two RJ45 Ethernet ports and two RJ45 serial ports, of which the COM3 port is RS-232C with a modem control signal, while the COM4 port is isolated for the connection of the configuration tool.

The PM857K02 module supports S800 I/O high integrity and is SIL3 certified, ensuring reliability and security in critical applications. In addition, it is fully EMC certified and TUV SIL 2 and SIL 3 certified, and has built-in redundant Ethernet communication ports for industrial control applications requiring high availability and security integrity.

The high integrity of this module is due to the combination of the SM812 module and SIL certification software, which enables non-critical control solutions to be upgraded to SIL compliant control solutions. At the same time, AC 800M High-Integrity provides an IEC 61508 and TUV certified control environment that integrates security and business-critical process controls without sacrificing safety integrity.

The PM857K02 module can handle up to 128 I/O signals, which is particularly important in complex control systems that require large amounts of I/O processing. In addition, it includes a security processor unit, CEX bus expansion cable and RCU-Link cable to facilitate system expansion and connectivity.

Overall, the ABB PM857K02 (3BSE088386R1) is a powerful and versatile CPU module for industrial automation control applications that require high reliability and safety integrity.
