Siemens 6ES7138-4CA01-0AA0 is the PM-E 24 VDC power module for ET 200S. It feeds and monitors a documented load-voltage group and provides diagnostics for the connected potential segment.
The exact PM-E article must match the terminal base, load-voltage group, station sequence and diagnostic configuration. It is not a CPU and must not be described as a processor module.
Record the full article, terminal base, incoming and outgoing 24 VDC wiring, protective devices, potential-group boundary, module sequence, parameters and diagnostics. Isolate all supplies before replacement and verify voltage, polarity and downstream I/O after energizing.
Confirm the 24 VDC supply, polarity, protective device, conductor capacity and documented 10 A segment-current limit at 60 °C.
Preserve the approved PM-E terminal base, potential-group boundary, downstream module order and AUX routing.
Restore the configured load-voltage diagnostic behavior and verify controller messages, module indicators and all downstream channels.
Siemens identifies 6ES7138-4CA01-0AA0 as the ET 200S PM-E 24 VDC power module. The manual lists 15 mA maximum no-load input current, 10 A maximum current capacity at 60 °C and 1 W typical power loss.
Confirm the terminal base, 24 VDC potential group, polarity, external protection, downstream module sequence and configured load-voltage diagnostics before commissioning.
Obsolete / Discontinued by OEM
Siemens SiePortal lists 6ES7138-4CA01-0AA0 as PM410 Product cancellation since 2023-10-01. Confirm the complete article and revision, receiving-system compatibility, condition, availability and included items in the written quotation.
