Overview
- Use a supported TM-P15C, TM-P15S or TM-P15N terminal base for the power module.
- Feed only the specified 24–48 V DC load voltage and keep it consistent with all electronic modules in the group.
- Exclude 2DI AC120V ST, 2DI AC230V ST and 2DO AC24–230V/1A from this potential group.
- Keep the total current within 10 A and use the specified external short-circuit protection.
- Enable missing-supply diagnostics and allocate the status or option-handling interface only as required by the project.
6ES7138-4CA50-0AB0 SIMATIC ET 200S PM-E DC24–48V Power Module

At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7138-4CA50-0AB0 |
| Product Type | PM-E power module with diagnostics |
| Core Function | Feeding and monitoring a load-voltage group |
| Application | ET 200S electronic-module groups |
Group supply
The TM-P terminal base feeds the load supply into the potential group.
Supply diagnostics
Missing-load-voltage reporting is configurable and disabled by default.
Status evaluation
The optional status byte lets the controller evaluate the power-module state.
Product Overview
6ES7138-4CA50-0AB0 feeds and monitors the 24–48 V DC load supply for an ET 200S potential group through its associated TM-P terminal module.
The module separates the group supply from the backplane bus, provides green PWR and red SF indications, and supports configurable diagnostic reporting when the load voltage is missing.
Key Functions
Establish the monitored DC load group
The load voltage enters through the TM-P terminal module and must agree with the supply requirements of all electronic modules in the group.
Report a missing load supply
Enabling the no-load-voltage diagnostic sends the affected power-module fault to the DP master and lights SF indicators in the relevant potential group.
Provide status and option-handling interfaces
Configuration can allocate a one-byte status input, an eight-byte option-handling input/output interface or the combined nine-byte arrangement.

Frequently Asked Questions
Can I feed 48 V DC into 6ES7138-4CA50-0AB0 if some group modules need 24 V DC?
The applied load voltage must match the supply requirements of every electronic module in that potential group.
Why does 6ES7138-4CA50-0AB0 show no missing-supply diagnostic after a new configuration?
The missing-load-voltage diagnostic is disabled by default and must be enabled when that fault report is required.
Does 6ES7138-4CA50-0AB0 include its own short-circuit circuit breaker?
Short-circuit protection is external, with circuit-breaker tripping characteristics B or C specified for the module.
Which electronic modules must be excluded from a group supplied by 6ES7138-4CA50-0AB0?
The 2DI AC120V ST, 2DI AC230V ST and 2DO AC24–230V/1A modules are excluded from this DC power-module group.
How much input space is needed for only the status byte of 6ES7138-4CA50-0AB0?
The status-only configuration occupies one input byte.
Where do I connect L+ and M for 6ES7138-4CA50-0AB0?
Connect L+ to terminals 2 and 6 and M to terminals 3 and 7 on the matching TM-P terminal base.
Why can several SF indicators turn on when 6ES7138-4CA50-0AB0 loses load voltage?
With the missing-load-voltage diagnostic enabled, the affected power-module message is reported and the SF indicators of modules in that potential group light.
