6ES7138-4CA50-0AB0 PM-E Power Module

15 mm power module for monitored 24–48 V DC load-voltage groups in ET 200S stations.

Product Overview

Siemens 6ES7138-4CA50-0AB0 is the SIMATIC DP PM-E DC24..48V power module for ET 200S. It supplies and monitors a load-voltage group while maintaining electrical isolation from the backplane bus and adjacent power-module groups.

This article is handled as an ET 200S spare part under Product Cancellation. Engineering checks must cover terminal-module selection, circuit-breaker protection, current carrying capacity and the complete station power architecture.

System Fit and Applications

  • Supplying defined load-voltage groups in ET 200S stations
  • Separating adjacent power-module potential groups
  • Maintenance replacement in installed distributed I/O assemblies

The module monitors the applied load voltage; external protection and the 10 A current budget remain part of the station design.

Compatibility and Procurement Checks

  • Confirm the full ET 200S article number.
  • Verify the associated terminal module.
  • Check the 24–48 V DC load-voltage range.
  • Calculate the maximum 10 A group current.
  • Provide characteristic B or C circuit protection.
  • Review spare-part availability before shutdown.

Lifecycle Note

Siemens lists 6ES7138-4CA50-0AB0 under Product Cancellation. PM410 for ET 200S components was set on 01 October 2023; supply is therefore handled as spare-part availability, not as Active or Discontinued.
