The Omron S8BA-24D24D240LF is a 240 W DIN-rail UPS that takes 24 VDC in and delivers 24 VDC out, with a sealed lithium-ion battery inside. The battery is included and rated for a minimum 2.5-year service life. It ships with the battery communication cable and a 2.2 m USB cable for monitoring.
The 240 W real-power rating tells you the continuous load it can support — sized for a small control cabinet's 24 VDC bus feeding PLCs, I/O slices, and indicators. The 11.7 A maximum input current is the draw when charging the battery and powering the load simultaneously; size your upstream 24 VDC supply accordingly. DIN-rail mounting means it clips into the same profile as your other panel hardware — no separate bracket or shelf needed. The 5.83 x 3.94 x 3.94 inch footprint fits a standard 6-inch-deep enclosure. The lithium-ion chemistry gives a flatter discharge curve than lead-acid, so the output voltage stays closer to 24 VDC through the discharge cycle — less risk of a brownout on sensitive loads.
Listed to UL 508 and CSA C22.2 No. 107.1-01, plus CE and UKCA. That covers the panel-building standards for North America and the EU. Also compliant with EN 61000 for EMC — no external filter required for most industrial environments.
