The Siemens 6EP1333-7CA10 is a SITOP PSU100P power supply built for IP67 field mounting outside the control cabinet. It takes 120 V or 230 V AC with automatic range selection and delivers a stabilized 24 V DC output rated 5 A (133 W) through an M12 L-coded output connector, with a 7/8-inch input plug and a separate M12 alarm connector for the 24 V OK signal.
The IP67 rating and M12/7/8-inch plug connectors let the 6EP1333-7CA10 mount directly on a machine frame or outside a cabinet, where the DIN-rail and wall-mount SITOP models need an enclosure. At 5 A / 133 W it sits below the higher-current variant in the same connectorized PSU100P family, so it fits a single field device or a small distributed I/O drop rather than a full remote panel. The relay contact on the alarm connector reports the 24 V OK status without running a separate signal back to the control cabinet, and the 90% efficiency keeps self-heating low inside a sealed enclosure where convection cooling is limited.
