It converts a 24 V DC line-side feed (max. 4 A draw) into backplane power for the Ex-rated I/O stations in an ET200iSP rack. Dimensions are 60 mm wide, 190 mm high, 136.5 mm deep — it drops into the standard ET200iSP slot footprint, same as the I/O modules. Reverse polarity protection on the input saves a service call when the line is down and the tech is in a hurry. If you already have the ET200iSP rack in your BOM, this module is the correct power infeed — no cross-reference needed, no last-time-buy scramble. Typical power loss is 20 W — not negligible; make sure your cabinet cooling accounts for that dissipation, especially if the panel has a high density of these racks. The status indicator and diagnostic readable via IM 152 (Ex-specific backplane interface) give you a quick fault-isolation path without opening the Ex zone. CE mark is present, so the module complies with EU directives — no separate documentation hurdle for export or panel certification.","metaTitle":"Siemens 6ES7138-7EA01-0AA0 Power Supply, ATEX Ex de IIC T4","metaDescription":"Active Siemens 24 V DC power supply module for ET200iSP Ex I/O.
