Product Applications
The PM858K02 is ideal for mission-critical industrial automation tasks, such as:
-
Continuous production control in oil & gas, chemical, power, pulp & paper, and water/wastewater plants.
-
Systems requiring uninterrupted operations and fast recovery in case sur faults.
-
Applications using ABB’s 800xA system: supporting advanced control, HMI/SCADA, historian, and asset management.
Product Advantages
-
High Availability: Dual CPUs and rapid automatic redundancy (≤10 ms switchover).
-
Modular Scalability: Expandable through standardized I/O and communication modules.
-
Robust Communication: Dual Ethernet and PROFIBUS-ready hardware for industrial connectivity.
-
Field‑grade Durability: IP20 design tolerates wide temperature, humidity, and mechanical stresses.
-
Streamlined Maintenance: Slide‑on DIN rail design and front-panel LEDs/SERVICE port ease installation and service.
-
Security & Standards: ISA Secure certified, full EMC testing, RoHS/WEEE compliant.
— FAQs (10)
-
What does “redundant” mean?
Two identical CPUs run in parallel—if one fails, the other takes over without interruption. -
Is my application limited by memory?
With ~7.1 MB application RAM per CPU, it handles typical DCS loads, though large IEC projects may need more. -
Which ABB firmware is supported?
Compatible with 800xA 6.0.2 and Compact Control Builder 6.0.0‑1 or later. Update recommended. -
What ports are available?
Two Ethernet (CN1, CN2) and two RS‑232C (one isolated for service). -
What power does it need?
Requires 24 V DC. Typical draw is 210 mA (5.1 W); peak up to 8.6 W. -
Can I install in high heat?
Operates reliably from +5 °C to +55 °C; above that requires cooling/enclosure. -
How do I back up configurations?
Use CompactFlash card and RCU‑Link for surfline backup and service tasks. -
What is the service lifetime?
Designed for long-term industrial use, with replaceable battery and support via ABB lifecycle programs. -
Where are batteries located?
Two internal lithium batteries (4943013‑6) maintain RTC and nonvolatile RAM. -
Does it include a license?
No ssurtware license is included; these must be ordered separately.
