The 6ES7138-4CA60-0AB0 is a Siemens SIMATIC DP Power Module PM-E High Feature for the ET 200S distributed I/O system. It provides a 24 V DC supply rail with integrated diagnostics for the downstream electronic modules. Snaps onto the standard DIN rail alongside the ET 200S interface module and electronic modules, occupying a single 15 mm wide slot. Its 52 mm depth keeps the profile flush with adjacent I/O slices, which matters when planning gland-plate clearance in a shallow enclosure. Typical power loss is 0.35 W — negligible for the thermal budget inside a crowded panel, but worth noting if the backplane bus is already near its current limit.
Dimensions and panel fit
At 15 mm wide and 81 mm tall, this module fits the standard ET 200S slice footprint. The 52 mm depth is a direct fit for most 80 mm deep enclosures; verify the interface module depth if using a shallow gland plate.
