Product Overview
The Omron S8VK-S48024 is a high-capacity DIN-rail power supply for 24 VDC control systems with many connected devices. It delivers 480 W at 20 A from a single-phase 100–240 VAC feed and also accepts 90–350 VDC. The S8VK-S line combines Push-In Plus terminals with coated circuit boards, helping panel builders wire faster and giving added protection for equipment installed in demanding industrial settings. This 480 W model also provides a low-voltage detection output for remote monitoring.
Where this model fits
The 20 A rating suits large PLC and remote-I/O cabinets, valve groups, and control panels with many sensors, relays, or network devices. Its 60 mm width is useful when a high-current supply must fit into a crowded enclosure. A short power-boost function can cover brief startup demand, but the normal load still needs to remain within the continuous rating. For a smaller panel, the 240 W S8VK-S model offers half the current in a narrower body.
Choosing between S48024 and T48024
Choose S8VK-S48024 when the cabinet has 100–240 VAC single-phase power and Push-In wiring is preferred. Choose S8VK-T48024 for a 380–480 VAC two- or three-phase feed. The S model is narrower, has a larger short-term boost, and includes the low-voltage output; the T model uses screw terminals and connects directly to a higher-voltage plant supply.
Before ordering
Confirm that the normal load stays within 20 A and treat the 30 A figure as a brief boost only. Check output conductor size, branch protection, panel spacing, and the datasheet load limits for the chosen temperature and mounting. Stranded wires should use suitable ferrules in the Push-In Plus terminals. Two matching units may be operated in parallel only under Omron’s stated mounting and load-sharing conditions.

Best-Fit Applications
- High-current 24 VDC rail for large PLC and remote I/O cabinets
- Valve, sensor, and control power on packaging and material-handling lines
- Protected outdoor cabinets that benefit from coated boards and wide temperature range
- Space-limited OEM panels needing 20 A from a 60 mm-wide supply
- Backup supply pairs where either unit can carry the full control load
Buying Checklist
- Confirm the continuous load stays within 20 A; treat 30 A as brief boost capacity.
- Check the cabinet has single-phase power; choose S8VK-T48024 for a 380–480 VAC multi-phase feed.
- Verify the panel has 60 mm of rail width plus the required cooling space.
- Choose suitable ferrules for stranded wires entering the Push-In Plus terminals.
- Check whether the DC LOW output should connect to a PLC alarm input.
- Allow for a lower output limit at high temperature or with tight spacing.

FAQ for S8VK-S48024
What is the difference between S8VK-S48024 and S8VK-T48024?
Both deliver 480 W at 24 VDC, but they suit different cabinet feeds. S8VK-S48024 accepts 100–240 VAC single phase, uses Push-In Plus terminals, and is 60 mm wide; S8VK-T48024 accepts 380–480 VAC two or three phase, uses screw terminals, and is 95 mm wide.
What does the S8VK-S48024 low-voltage output do?
It provides a separate DC LOW output for a PLC input or alarm circuit. The signal turns off when the supply detects an output drop, at roughly 80% of rated voltage; it monitors the power-supply terminals, so measure at the load when exact voltage matters.
Can two S8VK-S48024 power supplies be connected in parallel?
Yes. Omron allows two matching S8VK-S units in parallel when their output voltages are closely matched and its mounting, spacing, and wiring rules are followed. For backup use, keep the total load within one unit’s 20 A capacity so either supply can carry it alone.
