Features:
- A front PWR indicator reports the presence of acceptable input and regulated backplane power.
- A removable terminal cover limits accidental contact with line-voltage connections.
- The normally open RUN relay can drive a remote operating-status circuit.
Choose IC655PWR500 when the calculated Series Five backplane demand fits within the six-amp rail; racks approaching that limit should be evaluated against the higher-capacity AC alternative rather than treated as interchangeable.
The selector-jumper position becomes part of the cabinet configuration record because an incorrect 115/230 VAC choice affects the supply before any PLC diagnostic can respond.
The RUN contact reports controller operation, not merely incoming line power, so a remote indication circuit should be interpreted together with the front PWR lamp during troubleshooting.

How IC655PWR500 fits a Series Five base
- Base position: The housing and rear connector are designed for the power-supply location at the far left of a CPU or I/O expansion base.
- Backplane role: Its regulated output feeds the logic electronics of the processor and plug-in modules rather than replacing their field-side supplies.
- Capacity planning: A proposed module set is acceptable only when the sum of maximum internal current demands remains within the available six-amp output.
- Expansion bases: Each additional base receives its own correctly sized supply, so capacity is evaluated rack by rack rather than across the installation as one total.
Conditions that preserve dependable rack power
- Cabinet temperature: Operation is intended between 0 and 60 °C, requiring enclosure ventilation that keeps the supply inside this range.
- Stored equipment: Unpowered units tolerate -20 to 70 °C, but should return to the operating range before energization.
- Moisture control: Relative humidity may reach 95% only without condensation, so cold equipment should acclimate before startup.
- Atmosphere: The installation location must be free of corrosive gases that could degrade terminals, conductors, or internal assemblies.
Reading local and remote power-state indications
- Green indication: The front PWR lamp is illuminated only while both the incoming AC source and regulated DC output are present at acceptable levels.
- Dark indicator: Loss of the lamp directs troubleshooting toward the branch supply, fuse, input selection, and internal output instead of the I/O channels.
- RUN contacts: The isolated normally open relay closes while the processor remains in RUN, allowing a separate status circuit to follow controller operation.
- Remote alarm: A properly rated lamp or annunciator connected through the relay can reveal a stopped controller without opening the enclosure.
Line-side connections and protective details
- Input terminals: Connect the AC line and neutral only after matching the selector-jumper position to the actual branch voltage.
- Fuse response: A 2 A, 250 V normal-blow fuse protects the input; repeated operation calls for fault investigation rather than fitting a larger rating.
- Ground separation: Chassis ground and signal common have distinct terminals, permitting the prescribed single bonding point in a multi-base installation.
- Accessible conductors: Replace the terminal cover after wiring so line-voltage points are not exposed during routine work around the rack.
