Product Overview
The S8VS-06024A is Omron's 60 W 24 VDC / 2.5 A DIN-rail switch-mode power supply with the indication monitor feature (the 'A' suffix), the smaller sibling of the already-done S8VS-12024 (120 W). The 60 W rating is the workhorse class for small-to-medium PLC panels, sensor junction boxes, and DeviceNet sub-networks — sufficient to power a CP1L-EM40DT1-D PLC (already done) plus 30+ digital I/O modules, or a 16-device DeviceNet network with 4 × CJ1W-DRM21 masters.
Why the maintenance forecast display matters
The S8VS-06024A's most unique feature is the maintenance forecast function, which monitors the electrolytic capacitor's aging (the most common failure mode for switch-mode power supplies) and displays the remaining lifetime as a percentage. The display updates in real-time based on the actual operating temperature and load profile — at 25 °C ambient and 50% load, the expected lifetime is 15+ years; at 50 °C ambient and 100% load, the lifetime drops to 5-7 years. The maintenance forecast output (transistor output) signals 'replace now' when the lifetime reaches 50% (typically 7-10 years in normal operation).
S8VS-06024A vs S8VS-06024 (no monitor) vs S8VK-G06024 (modern replacement)
The S8VS family is Omron's mature DIN-rail PSU line, with the S8VS-06024A being the monitored variant. Three main options at 60 W / 24 VDC: - S8VS-06024 (no 'A' suffix) — same 60 W 24 VDC output, no display, lower cost. The right pick for OEM high-volume applications where the display isn't needed. - S8VS-06024A (this SKU) — same 60 W 24 VDC output, with display. The right pick for industrial control panels where predictive maintenance is required. - S8VK-G06024 — Omron's newer S8VK-G series with 5-year warranty, similar specs, no display.
Class 2 output and parallel / series operation
The S8VS-06024A is UL 1310 Class 2 compliant — the output is power-limited to 100 VA / 5 A, which allows the wiring to be Class 2 cable (lower cost than non-Class 2) and exempts the installation from some NEC requirements. For 60 W at 24 VDC, the output is 2.5 A — well under the Class 2 limit. For parallel operation (two PSUs sharing a load for redundancy), the S8VS-06024A does NOT support true parallel — the foldback current-sharing characteristic of the PSU causes one unit to take more load than the other.

FAQ for S8VS-06024A
What's the difference between S8VS-06024A and S8VS-06024?
Both are 60 W 24 VDC / 2.5 A DIN-rail switch-mode power supplies with the same electrical specifications (100-240 VAC input, 85% efficiency, 33 ms hold-up, Class 2 output).
How does the maintenance forecast function work on the S8VS-06024A?
The maintenance forecast function monitors the electrolytic capacitor's aging, which is the most common failure mode for switch-mode power supplies. The function uses a combination of internal temperature sensors and load-current monitoring to estimate the cap's remaining lifetime, which is displayed as a percentage (100% = new, 50% = replace now, 0% = end of life). The estimate is based on the Arrhenius equation for electrolytic cap aging — every 10 °C increase in operating temperature halves the cap life.
Can I parallel two S8VS-06024A power supplies for redundancy?
The S8VS-06024A does NOT support true parallel operation — the foldback current-sharing characteristic causes one unit to take more load than the other, leading to premature failure of the heavily-loaded unit. For redundant operation (where one PSU takes over if the other fails), use the S8VK-R10 redundancy module (diode OR'ing) between the PSUs and the load. Each PSU operates at <50% load in normal operation, and if one PSU fails, the other takes the full load.
Is the S8VS-06024A UL 1310 Class 2 compliant?
Yes — the S8VS-06024A is UL 1310 Class 2 compliant, meaning the output is power-limited to 100 VA / 5 A. For 60 W at 24 VDC, the output is 2.5 A — well under the Class 2 limit. The Class 2 compliance allows the wiring to be Class 2 cable (lower cost than non-Class 2) and exempts the installation from some NEC requirements.
