The ABB PM864AK02 (3BSE018164R1) is a high-performance CPU kit designed for the AC800M controller platform, specifically configured for redundant applications. This model ensures maximum system availability by providing a hot-standby processor pair capable of seamless bumpless failover in critical industrial processes.

 

Technical Specifications

 

Operational Precautions

• Battery Maintenance: Regularly check the backup battery (SB821/SB822) to ensure user programs and data are retained during power loss.
• Redundancy Link: Use the dedicated redundancy cable to connect the primary and backup units; ensure connections are locked to prevent communication drops.
• Firmware Matching: Both processors in a redundant pair must run identical firmware versions to synchronize correctly.
• Heat Dissipation: Ensure the baseplate is mounted vertically to allow natural convection cooling across the processor fins.

 

Common Q&A

Q: What is included in the PM864AK02 “Kit”? A: The kit typically includes two PM864A processor units, two TP830 terminations, and the necessary redundancy communication hardware.

Q: Can I use this processor for SIL-rated safety functions? A: While the PM864A is highly reliable, specific safety applications usually require the High Integrity (HI) versions, such as the PM865 or PM867.

Q: Does it support online code changes? A: Yes, the AC800M platform allows for “Download in Operation,” enabling logic updates without stopping the controlled process.
