The Omron S8VK-C24024 is a 240 W switched-mode power supply that converts a single-phase 100–240 VAC input to a regulated 24 V DC output at 10 A. It's built for DIN-rail mounting in control cabinets, with screw terminals for field wiring. The 24 V DC rail is the standard control voltage for PLCs, sensors, relays, and HMI panels — this unit powers that bus. With 240 W on tap, it can handle a mixed load of several amps of digital I/O plus a modest analog loop supply. Efficiency peaks at 87 %, which keeps heat dissipation manageable inside a sealed panel. The MTBF of 270,000 hours (roughly 30 years continuous) is a solid reliability figure for a critical-spare application — one in the cabinet, one on the shelf.
Input accepts 85–264 VAC, 47–63 Hz, covering global line voltages without a tap change. That single-phase input means it's suited for standard North American 120 V or European 230 V branch circuits — no three-phase feed needed. Output voltage is adjustable, so you can trim the 24 V rail up or down a few percent to compensate for voltage drop in long cable runs to remote I/O nodes. The 0.15 V ripple and noise figure is tight enough for sensitive analog inputs — no external post-filter required for most applications. Storage temperature range of –25 to 65°C covers most warehouse and shipping conditions.
The approvals list — CE, cRUus, CSA C22.2 No. 107.1/62368-1, EN55011 Class A, EN61204-3, EN62368-1, EN62477-1, UL Listed, UL508/62368-1 — covers North American and European installations, so it drops into panels destined for either market without a compliance re-spin.
DIN-rail mount, book-type format — 60 mm wide, 125 mm tall, 140 mm deep. The screw terminals accept 20–10 AWG, so you can land 2.5 mm² stranded for the DC output without a ferrule, though a ferrule is recommended for stranded wire in vibration environments. The green DC OK indicator gives a quick visual that the output is within spec — useful during commissioning or fault isolation. No fieldbus or remote monitoring on this unit; it's a straightforward power supply, not a managed PSU.
