This document is the manual of the Siemens PM-E DC24V (6ES7138-4CA01-0AA0) power module.
The document serves as a user guide for the Siemens PM-E DC24V power module (part number 6ES7138-4CA01-0AA0), which is part of the SIMATIC ET 200S distributed I/O system. It details how to monitor supply voltage, manage electronic modules within a voltage group, and interpret diagnostic status bytes.
The manual provides technical specifications including electrical isolation, current carrying capacity, and terminal assignments. It also explains how to configure the address space for option handling and status byte evaluation using configuration software like STEP 7.
| Rated load voltage | 24 VDC |
|---|---|
| Maximum current carrying capacity | 10 A |
| Insulation test voltage | 500 VDC |
| Current consumption (no load) | Max. 4 mA |
| Power dissipation | Typically 100 mW |
The module monitors the supply voltage for all electronic modules in its voltage group.
You cannot use 2DI AC120V ST, 2DI AC230V ST, and 2DO AC24..230V/1A in the voltage group.
The module features a Red "SF" LED for group errors and a Green "PWR" LED for load voltage monitoring.
