Overview
- Choose TM-P15S, TM-P15C or TM-P15N with the required AUX1 routing.
- Keep the group current at or below 10 A.
- Set missing-voltage diagnostics deliberately.
- Reserve the process-image allocation for the selected configuration.
6ES7138-4CA01-0AA0 SIMATIC ET 200S PM-E DC24V Power Module with Diagnostics
A 24 V DC PM-E module that monitors group load voltage and provides status and diagnostic information.
At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7138-4CA01-0AA0 |
| Product Type | Power module |
| Core Function | Potential-group supply monitoring |
| Application | ET 200S electronic-module groups |
Group voltage monitoring
The module monitors the supply fed through its associated TM-P base.
10 A group capacity
The complete potential group must remain within the maximum current-carrying capacity.
Status in the process image
The status byte updates independently of enabling the missing-load-voltage diagnosis.
Product Overview
6ES7138-4CA01-0AA0 monitors the external 24 V DC load supply for an ET 200S potential group.
The terminal module provides the supply connection, while green PWR and red SF indicators and the configured process-image status support commissioning and fault location.
Key Functions
Supervise the group load supply
The missing-load-voltage diagnostic can be enabled for the affected power group.
Provide local power and fault indication
The green PWR indicator represents the rated load-voltage state and the red SF indicator signals a group error.
Expose status to the controller
Status-only, option-handling and combined configurations provide different process-image allocations.

Frequently Asked Questions
Does 6ES7138-4CA01-0AA0 generate 24 V DC from an AC supply?
No, the load voltage must be supplied externally as 24 V DC through the TM-P terminal module.
How do I decide how many electronic modules can follow 6ES7138-4CA01-0AA0?
Add the current demands of the complete potential group and keep the total within the 10 A current-carrying limit.
Will the status byte of 6ES7138-4CA01-0AA0 stop updating if missing-voltage diagnostics are disabled?
No, the status byte continues to update independently of the missing-load-voltage diagnostic setting.
Can 6ES7138-4CA01-0AA0 protect its potential group against a short circuit by itself?
No, the module has no integrated short-circuit protection and requires suitable external circuit protection.
What is the default missing-load-voltage diagnostic setting of 6ES7138-4CA01-0AA0?
The diagnostic is disabled by default and can be enabled in the power-module parameters.
Can I include 230 V AC output modules in the potential group supplied through 6ES7138-4CA01-0AA0?
No, the 2DI AC120V ST, 2DI AC230V ST and 2DO AC24–230V/1A modules are excluded from this 24 V DC potential group.
Which screw-terminal bases can I choose for 6ES7138-4CA01-0AA0?
Compatible screw-terminal choices include TM-P15S23-A1, TM-P15S23-A0 and TM-P15S22-01, with different auxiliary-bus arrangements.
