The Omron S8BA-24D24D480SBF is a DIN-rail-mount UPS that takes 24 V DC in and delivers 24 V DC out at 480 W, with a lithium-ion battery built in. It's sized for control cabinets where you need ride-through for a 24 V DC bus — think PLC racks, remote I/O, or valve islands that can't brown out during a sag. The battery is included and rated for a minimum 2.5-year life, so you're not sourcing cells separately. DIN-rail mounting means it clips into the same profile as your terminal blocks and breakers — no drilling, no separate backplate. The 10.63-inch width (about 9 DIN units) is a standard slot count; plan for that when laying out the panel.
480 W real power at 24 V DC output means it can support a load drawing up to 20 A continuously. The input draws a maximum of 21.5 A at full load, so factor that into your upstream 24 V DC supply sizing — you need a power supply that can handle the charge current plus the load during normal operation. The audible alarm and visible indicator for overload conditions give you a local alert before the battery depletes. The RJ45 serial output port allows communication with a PLC or SCADA for remote monitoring of UPS status — battery health, load, and alarm conditions. That's useful for a line-down scenario where you want a heads-up before the battery runs flat.
Compliance and approvals at a glance
Carries UL 508, CE, UKCA, and CSA C22.2 No. 107.1-01 approvals, plus EN 61000 for EMC. That covers North American and European panel builds — no extra certification paperwork for most industrial control panels. The UKCA mark keeps it valid for UK installations post-Brexit.
