ABB DCP02 – Redundant Power Supply for Industrial Control Systems
The ABB DCP02 is typically found in AC 800M and Symphony Plus control systems, where stable DC power distribution is critical. From my experience, it’s not just a power module—it’s part of a redundancy strategy that keeps process automation lines running even during partial failures. One thing I appreciate is how quietly it operates in the background; you don’t notice it until something goes wrong elsewhere.
Key Features
- Redundant Design: Works in parallel with another DCP02 to provide failover capability—so if one unit fails, the other picks up the load without interruption.
- DC Voltage Regulation: Delivers a clean, regulated 24 VDC output, which seems to be especially important for sensitive I/O modules downstream.
- Hot-Swappable: Can be replaced without powering down the system, minimizing downtime during maintenance.
- Status Indicators: LED diagnostics make troubleshooting faster—green for normal operation, red for faults like overvoltage or short circuits.
- Compact Form Factor: Fits standard ABB rack enclosures, saving space in crowded control cabinets.

Application Fields
You’ll typically find the DCP02 deployed in heavy-industry environments—oil & gas processing plants, power generation stations, and large-scale water treatment facilities. It’s built for systems where a momentary power drop could trigger cascading failures. In many cases, these are used alongside ABB’s AC 800M controllers to power distributed I/O racks across turbine control or boiler management setups.
Advantages & Value
While it might seem like a simple power module, its real value lies in system resilience. Procurement teams often overlook redundancy at the power level—until they face an unplanned shutdown. The DCP02 helps avoid that. Since it supports hot-swapping and pairs seamlessly with its twin, uptime improves noticeably. Also, because it’s an ABB original, integration with existing Symphony or MOD 30 platforms tends to be plug-and-play, reducing commissioning time.
Installation & Maintenance
Mount it on standard 35 mm DIN rail inside an IP54-rated cabinet—preferably with some airflow, since ambient temps above 55°C can reduce lifespan. Make sure input wiring uses at least 1.5 mm² stranded copper with proper ferrules. One common mistake I’ve seen: skipping the grounding screw on the rail base, which can lead to noise issues later. For maintenance, visually inspect LEDs quarterly, clean dust from vents annually, and check firmware compatibility after any system-wide updates—even though it doesn’t communicate digitally, version matching matters during replacements.
Quality & Certifications
The DCP02 carries CE, UL, and RoHS certifications, confirming compliance with major international safety and environmental standards. It’s designed and tested under ISO 9001 processes. We offer a 365-day warranty against manufacturing defects. If installed correctly and operated within spec, it should last 7+ years in most industrial settings.
