Product Overview
The Omron S8VS-18024AP is a 24 VDC power supply for control panels where maintenance staff need clear load readings and remote alerts. Its front display shows output voltage, present current, peak current, and the estimated time remaining before maintenance. Separate low-voltage and maintenance outputs can report status to compatible PLC inputs. The supply mounts on DIN rail, uses screw terminals, and accepts a single-phase AC feed or an allowed DC input.
Why choose the AP version?
The AP suffix identifies sourcing transistor alarm outputs. Choose this version when the PLC input wiring is designed for a sourcing signal. The S8VS-18024A has the same maintenance display but uses sinking outputs, while the standard S8VS-18024 omits the display and remote alarms. For a smaller monitored load, S8VS-12024AP provides the same sourcing output style at 5 A.
What the maintenance reading means
The forecast follows operating time and temperature inside the supply to estimate aging of its capacitors. It helps a maintenance team plan an inspection or replacement, but it does not predict faults from every possible cause. The alarm terminals are transistor outputs for low voltage and the forecast threshold. They are not dry relay contacts, and they do not provide an 80% load warning.
Before ordering
Add the normal current of the PLC, I/O, HMI, sensors, relays, and other connected loads. Keep that total within the continuous rating and allow room for later additions. Verify the PLC input type and common wiring before connecting either alarm. Omron does not support parallel connection to increase output current. Use the standard upright mounting position, leave cooling space, and check the reduced load limit when a DC input below 100 V is used.

FAQ for S8VS-18024AP
What is the difference between S8VS-18024AP and S8VS-18024A?
Their alarm output style is different. S8VS-18024AP has sourcing transistor outputs, while S8VS-18024A has sinking outputs. Both include the maintenance forecast display. Match the model to the PLC input wiring rather than treating the P suffix as an extra alarm feature.
Can the S8VS-18024AP alarm outputs connect to a PLC?
Yes, if the PLC input is compatible with a sourcing transistor signal. One output reports low voltage and the other reports the maintenance threshold. They share a common and are not voltage-free relay contacts, so check the input circuit before wiring them.
Does the S8VS-18024AP forecast every power-supply failure?
No. The forecast estimates capacitor aging from operating time and temperature inside the supply. Omron states that it does not predict failures caused by other reasons. Use it to plan inspection or replacement, not as the only check on control-power health.
