6ES7138-4CA01-0AA0 | Siemens | SIMATIC DP Power Module

Description

6ES7138-4CA01-0AA0 is a SIMATIC DP Power Module (PM-E) designed for use with the ET 200S system. As a dedicated PLC power module, it delivers reliable power support for industrial automation setups. Key technical specifications include a rated load voltage L+ of 24V DC, with a maximum no-load input current of 4mA from the L+ load voltage. It offers a maximum current carrying capacity of 10A at up to 60 degrees Celsius, with a typical power loss of 0.1W.

The module features built-in reverse polarity protection, and its short-circuit protection requires an external trigger with a type C characteristic. It incorporates primary/secondary potential isolation, providing insulation between the load voltage and backplane bus, as well as between adjacent power modules, with insulation tested at 500V DC. Diagnostic capabilities are supported via LED indicators: a green PWR light for rated load voltage status, a red SF light for cumulative faults, and detection for load voltage loss.

With compact dimensions of 15mm width, 81mm height, 52mm depth and a weight of approximately 35g, it is optimized for space-efficient DIN rail installation in standard industrial control environments, supporting stable power distribution for PLC-based automation systems.
