Features:
- A 20 to 29 VDC source powers the rack without an AC voltage-selection jumper.
- The regulated six-amp rail serves Series Five backplane electronics.
- Front indication and isolated RUN contacts expose two different operating states.
A DC-fed rack can share the plant's control-power strategy while IC655PWR514 performs the final conversion to the tightly regulated logic voltage required inside the base.
Positive and negative input terminals replace the hot, neutral, and voltage-selection arrangement used on the AC models, reducing the chance of applying an irrelevant jumper configuration to this version.
Power planning remains local to each base: the installed processor and module loads consume the available output, whereas most field-side devices stay on their separately engineered supplies.
Apter Power can help source and support the General Electric IC655PWR514 24 VDC Input, 6 Amp Power Supply Module for retained Series Five DC-powered racks.

Bringing a plant DC source into the Series Five base
- Source window: The upstream bus must stay between 20 and 29 VDC under charging, battery, and load-transient conditions.
- Polarity path: Positive and negative conductors land on dedicated terminals, so polarity can be checked directly before the rack is energized.
- Backplane conversion: IC655PWR514 isolates the field-source decision from the internal requirement by delivering regulated 5.1 VDC to installed logic modules.
- Base allocation: CPU and expansion racks are each assessed against the capacity of their own fitted supply rather than borrowing power across the I/O cable.
Keeping the DC supply inside its thermal envelope
- Operating air: The temperature entering the module area must remain between 0 and 60 °C during energized service.
- Condensation risk: Humidity up to 95% is permitted only when moisture does not form on the supply or base conductors.
- Convection path: Horizontal mounting and unobstructed openings allow heat to rise through the base without forced-air cooling.
- Service clearance: Recommended 50 mm spacing around neighboring bases supports heat flow and permits the supply to be removed without obstruction.
Interpreting IC655PWR514 status signals
- Local lamp: Green PWR illumination indicates that the DC source is present and the internal +5 VDC rail is within its operating level.
- Loss indication: A dark lamp directs the technician to check source voltage, polarity, fuse continuity, and the regulated output path.
- Processor contact: The normally open RUN relay closes with CPU RUN mode and opens when the controller leaves that state.
- Hardwired reporting: Because the relay is separate from programmed I/O, an external alarm can continue to show controller state during application troubleshooting.
Avoiding damaging potential differences between bases
- Single bond: Connect the C-to-G jumper only at the first CPU base when more than one powered base shares the system.
- Common reference: Carry all C conductors together and all chassis-ground conductors together so the linked racks do not float apart.
- Input fuse: Use the specified six-amp normal-blow fuse for IC655PWR514 instead of adopting either AC supply's protection value.
- Covered terminals: Refit the snap-on guard after source and ground wiring to prevent unintended contact during rack maintenance.
