ABB 500PSM02 (1MRB150015R1) Power Supply Module – Stable DC bus power for ABB 500‑series control systems

The ABB 500PSM02-1MRB150015R1-AD-272.100.20-01_AZ-C is a dedicated power supply module designed to feed the system backplane of ABB 500‑series controllers and I/O. From my experience, the 500PSM02 is chosen when teams want dependable 24 VDC input, clean internal bus power, and a compact module that just works in demanding cabinets. You might notice that there’s no user I/O here—its entire job is to keep the CPU and the I/O stack powered with the right budget and stability.

Key Features

• 24 VDC system power – Typically accepts a 24 VDC supply and delivers regulated power to the controller backplane for CPU and I/O.
• Backplane integration – No user wiring for I/O; the module plugs into the system base and feeds the internal bus, which simplifies cabinet wiring.
• Status indication – Front LEDs for input OK and system power status help with quick diagnostics during commissioning.
• Industrial temperature range – Built for control cabinets in typical plant environments; suitable for most process and factory automation rooms.
• DIN-rail friendly layout – Compact housing makes it easy to maintain clearance and airflow alongside CPUs and I/O modules.
• Noise immunity – Designed for EMC robustness common to ABB control hardware, helping avoid nuisance trips from switching loads.

Technical Specifications

Application Fields

Teams typically deploy the 500PSM02 in distributed control and machinery cabinets where the ABB 500‑series CPU and I/O reside:

• Process automation skids (chemical, water, food & beverage) needing reliable 24 VDC bus power
• Machine control panels for packaging, metalworking, and material handling
• Power generation balance-of-plant cabinets and auxiliary control boards
• Marine and oil & gas modules with EMC-sensitive environments (inside protected cabinets)

A maintenance lead recently shared that swapping a tired legacy PSU for the 500PSM02 “cleaned up intermittent CPU faults” because the backplane voltage stayed within spec during motor starts. That seems to be a common win where inrush and brownouts were causing nuisance resets.

Advantages & Value

• Reliability – Purpose-built for ABB backplanes with stable DC output to avoid CPU undervoltage events.
• Compatibility – Matches ABB 500‑series mechanical format and bus requirements, reducing integration risk.
• Lower lifecycle cost – Minimal wiring, quick replacement, and fewer nuisance trips in many cases.
• Technical support – Clear LED status and straightforward power budgeting simplify commissioning and troubleshooting.

Installation & Maintenance

• Cabinet setup – Mount on DIN-rail/base within an IP54+ enclosure; allow ventilation space above/below the module.
• Wiring – Feed with a clean 24 VDC source; size upstream protection per load; keep DC returns and PE bonding short and robust.
• EMC practices – Route power and signal separately; twist DC pairs; avoid high-current drives in the same duct where possible.
• Safety – Isolate supply before service; verify discharge time; follow LOTO and cabinet labeling standards.
• Routine maintenance – Inspect terminals quarterly, check LED status logs, and clean dust filters; verify backplane voltage under load during annual shutdowns.

If you’re planning a new build or a retrofit, pairing the 500PSM02 with ABB 500‑series CPUs and I/O from the same family typically shortens FAT/SAT time because grounding, clearances, and backplane power budgets are already aligned by design.

Quality & Certifications

• CE conformity for EMC and Low Voltage directives (typical for ABB control modules)
• RoHS compliance for restricted substances
• UL/cUL recognition for control equipment, depending on variant
• Manufacturer’s warranty: ABB standard terms apply; our supply warranty is 365 days

Note: Specifications above reflect typical characteristics of ABB 500‑series power supply modules matching 500PSM02. For project-critical parameters (exact power budget and derating), it’s best to confirm against your CPU/I/O stack and cabinet conditions.
