At a Glance

Brand	Siemens
Model	6ES7138-4CB10-0AB0
Product Type	Electronic-module power module
Core Function	Supplying and monitoring a potential group
Application	Compatible ET 200S electronic modules

AC or DC load circuit

Select the load-voltage type in the hardware configuration.

Three local indicators

SF, PWR and FSG distinguish group fault, load voltage and fuse status.

Status feedback

The status byte is updated independently of the missing-load-voltage diagnostic setting.

Product Overview

6ES7138-4CB10-0AB0 feeds and monitors the load-voltage group of compatible ET 200S electronic modules through its TM-P terminal base, with parameter selection for AC or DC operation.

A replaceable fuse and separate load-voltage and fuse indications support maintenance, while the process-image interfaces support option handling and current status feedback.

Ordering focus: Match the TM-P base and connected electronic-module voltage, select AC or DC in the configuration, and apply the appropriate current derating and external protection.

Key Functions

Distribute and monitor the load voltage

The TM-P terminal module feeds the potential group, and the PM-E monitors the voltage supplying its downstream electronic modules.

Separate supply and fuse status

The module provides a red SF group-fault indicator, a green PWR load-voltage indicator and a green FSG fuse indicator.

Support option handling and status feedback

The power module has control and feedback interfaces in the process image, and its current status byte is updated even when missing-load-voltage diagnostics are disabled.

Frequently Asked Questions

Do I have to change the configuration when using 6ES7138-4CB10-0AB0 on an AC load circuit?

Set the load-voltage type parameter to AC because its default setting is DC.

Can 6ES7138-4CB10-0AB0 directly replace the older 4CB00 variant in an AC application without a configuration change?

An AC application requires a new hardware configuration with the AC load-voltage type selected.

What should I use to replace the internal fuse in 6ES7138-4CB10-0AB0?

Use the specified 5 × 20 mm, 250 V, 10 A fast fuse complying with IEC 127-2/1.

Does the internal fuse in 6ES7138-4CB10-0AB0 replace the external supply-line protection?

The internal fuse is additional protection and external overcurrent protection is still required in the load-circuit supply lines.

Can I load 6ES7138-4CB10-0AB0 to 10 A in a 60 °C DC installation?

The DC current limit at 60 °C is 7 A rather than 10 A.

What does the FSG light on 6ES7138-4CB10-0AB0 help me monitor?

The green FSG indicator shows the fuse status separately from the PWR load-voltage indication.

Will disabling missing-load-voltage diagnostics stop the status byte of 6ES7138-4CB10-0AB0 from updating?

The current status byte continues to update independently of whether that diagnosis is enabled.

Compatibility & Ordering Notes

Before ordering 6ES7138-4CB10-0AB0: Retain the full 4CB10 article and the correct TM-P base, align every electronic module with the selected supply voltage, and provide both the correct fuse and external supply protection.

Compatibility Checklist for 6ES7138-4CB10-0AB0

• Choose the compatible screw, spring or FastConnect TM-P terminal-base variant for the wiring arrangement.
• Select the connected load-voltage type as AC or DC in the hardware configuration.
• Apply the separate AC and DC current limits at the actual ambient temperature.
• Use the specified replaceable internal fuse and provide external protection in the load supply lines.
• For an AC replacement of 4CB00, update the hardware configuration before commissioning.
• Include the required power module in the ET 200S configuration, accounting for the separate IM151-1 COMPACT arrangement.
