SKU: 6ES7138-4HA00-0AB0 Category: PLC

Description
Additional information

The Siemens SIMATIC ET 200S module 6ES7138-4HA00-0AB0 is a power module belonging to the ET 200S distributed I/O system family. It is designed to function as a motor starter or load feeder module within the ET 200S station, providing power distribution and protection for connected loads. This module integrates directly into the ET 200S backplane and is managed via PROFIBUS DP or PROFINET communication from a central controller.

The 6ES7138-4HA00-0AB0 is a high-feature power module (PM-E) for the ET 200S system, supplying 24 V DC to the electronic modules downstream in the station. It supports diagnostic functions including short-circuit and overload detection, and provides group diagnostics back to the CPU. The module features LED status indicators for power and fault states, and supports potential group isolation, allowing different voltage segments within a single ET 200S station.

This module is widely used in machine automation, conveyor systems, and process plant installations where distributed I/O is required close to the field devices. Its compact form factor and modular design make it suitable for control cabinet installations in automotive manufacturing, food and beverage processing, and general factory automation. The ability to create isolated potential groups within the ET 200S station simplifies wiring and enhances safety in multi-voltage installations.

Common Diagnostic Fault Codes

Fault Code 1: Short circuit detected on the output or load circuit of the power module.
Disconnect the load, identify and remove the short circuit, then re-enable the module via the CPU or reset the station.
Fault Code 2: Overload condition detected; output current exceeds the rated limit.
Reduce the connected load to within the rated current specification. Check wiring and connected devices for excessive current draw.
Fault Code 3: Supply voltage missing or below permissible range on the PM-E module.
Verify that the 24 V DC supply to the power module is within tolerance. Check fuses and supply wiring upstream of the module.
Fault Code 4: Module not recognized or configuration mismatch detected by the CPU.
Verify the hardware configuration in STEP 7 or TIA Portal matches the physical module installed. Re-download the configuration to the CPU.
Fault Code 5: Potential group isolation fault; incorrect voltage applied to a downstream potential group.
Check the wiring of the potential group and verify that the correct supply voltage is connected to the appropriate terminals.
Fault Code 6: Module removed or missing during operation (station diagnostics alarm).
Re-insert the module into the correct slot. Verify the slot assignment in the hardware configuration matches the physical installation.
Fault Code 7: Internal module fault detected; hardware failure within the PM-E module.
Replace the 6ES7138-4HA00-0AB0 power module. Ensure the replacement module matches the exact part number and firmware requirements.

Frequently Asked Questions

Which software is used to configure the 6ES7138-4HA00-0AB0?

The module is configured using Siemens STEP 7 (v5.x) or TIA Portal, depending on the CPU and PROFIBUS DP or PROFINET interface module used in the ET 200S station.

Does the 6ES7138-4HA00-0AB0 support diagnostics?

Yes, the module provides diagnostic functions including short-circuit and overload detection, with diagnostic alarms transmitted to the controlling CPU via the fieldbus.

What is the maximum continuous output current of this power module?

The 6ES7138-4HA00-0AB0 supports a maximum continuous output current of 10 A at 24 V DC for the downstream module supply.

Troubleshooting

All downstream ET 200S modules lose power after the PM-E module

Check the SF and PWR LEDs on the power module. Measure the 24 V DC input supply voltage at the module terminals. Inspect upstream fuses and circuit breakers.

Restore the 24 V DC supply to within tolerance. Replace any blown fuses upstream of the module. If the module itself has failed internally, replace the 6ES7138-4HA00-0AB0.

SF (System Fault) LED is lit on the power module

Read the diagnostic buffer of the CPU using STEP 7 or TIA Portal to identify the specific fault code. Check for short circuits or overloads on the connected load circuits.

Resolve the identified fault (short circuit, overload, or configuration mismatch), then acknowledge the fault via the CPU program or perform a station reset.

ET 200S station reports a configuration error after module replacement

Compare the part number and order number of the replacement module with the original. Verify the hardware configuration in STEP 7 or TIA Portal matches the installed module type and slot position.

Update the hardware configuration in STEP 7 or TIA Portal to reflect the correct module, then re-download the configuration to the CPU and perform a station restart.

Module is not recognized by the CPU after installation

Check that the module is fully seated in the ET 200S backplane and that the terminal module is correctly installed. Verify the slot assignment in the hardware configuration.

Re-seat the module firmly into the terminal module. Correct the slot assignment in the hardware configuration if necessary and re-download to the CPU.

Intermittent power loss to downstream modules

Monitor the 24 V DC supply voltage for voltage dips or instability using a multimeter or oscilloscope. Check all wiring connections at the module terminals for looseness or corrosion.

Stabilize the 24 V DC supply, tighten or replace any loose terminal connections, and ensure the power supply unit feeding the PM-E module is adequately rated for the total station load.
