Applications
The PM857K02 serves as a central processing unit in ABB System 800xA and AC 800M architectures. It is used for:
-
Critical industrial process control in oil & gas, power, chemical and refining
-
Integrated safety and process automation with SIL‑3 support
-
Systems requiring high availability via redundancy
-
Complex automation requiring up to 128 I/O points
It integrates seamlessly with S800 I/O, communication modules, and full 800xA Control Builder software.
Advantages
-
High Integrity & Safety: Achieves SIL‑3 certification with safety module support
-
Redundant Architecture: Multiple communication and CPU redundancy ensure minimal downtime
-
Flexible Connectivity: Ethernet + RS‑232 ensures legacy and modern system interfacing
-
Compact, Rugged Design: DIN‑rail mounting with compact footprint withstands industrial environments
-
Seamless Integration: Fully compatible with 800xA environment and Control Builder tool
-
Reliable Timekeeping: Built-in lithium RTC with battery backup ensures accurate timestamping
FAQ
-
Is it compatible with older PM857K01?
Yes—designed as a direct upgrade with similar form factor.
-
What is included in the package?
Generally shipped with 2 × PM857K01 safety modules, CEX-bus and RCU cables
-
Can it run stand-alone without redundant CPU?
Yes—but redundancy must be disabled and configured in software.
-
Does it include a Control Builder license?
No; programming tool license is purchased separately.
-
How long is the warranty period?
We provide one year warranty
-
What’s the power draw?
Approx. 210 mA typical; 360 mA max at 24 V DC
-
Can I hot-swap it?
Supports hot-swap for communication and I/O modules; CPU swap requires controlled procedure.
-
RTC lifetime?
Lithium battery typically lasts 5–7 years, field‑replaceable.
-
What certifications does it hold?
SIL‑2/3, EMC, CE, TÜV, ISA G3 corrosion.
-
Which software versions support it?
Compatible with System 800xA and AC 800M Control Builder spanning versions 5.x to current.
