Product Overview
The Siemens 6AG2138-6AA01-1BA0 is an active product within the SIPLUS extreme RAIL technology family. It serves as a robust counter module engineered for demanding operational conditions.
Based on the 6ES7138-6AA01-0BA0 foundation, this unit features conformal coating for enhanced protection. It supports 24 V incremental or pulse generator signals across a single channel.
Technical Review Notes
- This module operates reliably within a temperature range of -40 to +60 degrees Celsius. It withstands overload temperatures up to 70 degrees Celsius for ten-minute durations.
- The device integrates three digital inputs alongside its primary counting functionality. It utilizes the T1 RAIL standard for secure mounting and signal transmission.
- Conformal coating provides additional resistance against moisture, chemicals, and corrosive agents. This ensures consistent performance in extreme environmental conditions over extended periods.
- The net weight of the unit is recorded at 0.053 kilograms. Its compact dimensions measure 7.8 by 6.4 by 2.3 centimeters for space-efficient installation.
- Signal processing handles 24 V incremental or pulse generator inputs effectively. The single-channel design simplifies integration into existing control architectures.
- The product class indicates review restrictions requiring direct contact with Siemens review contacts. This classification applies to specific handling protocols for this hardware component.
Model Identification
- The part number 6AG2138-6AA01-1BA0 uniquely identifies this specific SIPLUS extreme variant. It distinguishes the coated version from standard industrial ET 200SP modules.
- Normalization removes hyphens for database matching, resulting in 6AG21386AA011BA0. This format aids in precise technical documentation and cross-referencing.
- The suffix 1BA0 denotes the specific configuration including the conformal coating. This differentiates it from the base model 0BA0 without environmental protection.
- Category placement under I/O Modules reflects its function as a terminal module. It connects directly to the SIMATIC ET 200SP base unit.

Parameter Review
- Review the operating temperature limits before deployment in extreme climates. The -40 to +60 C range defines standard operational boundaries for this hardware.
- Check the overload temperature tolerance for short-term thermal stress events. The ST1/2 rating allows 70 C for ten minutes without damage.
- Verify the input signal type matches your application requirements. The module accepts 24 V incremental or pulse generator signals on its single channel.
- Confirm the physical dimensions fit your rack or panel layout. The 7.8 x 6.4 x 2.3 cm size requires specific spatial planning.
- Note the weight specification for logistics and mounting calculations. At 0.053 kg, the unit adds minimal load to the carrier rail structure.
Catalog Classification
Image & Label Review
- Images typically display the front face with terminal blocks visible. The conformal coating may appear as a distinct protective layer on the circuit board.
- Labeling includes the full part number for easy identification during inspection. Verify the printed text matches the 6AG2138-6AA01-1BA0 designation precisely.
- Mounting clips and rail attachment points are often shown in side views. These features ensure secure installation within the SIMATIC ET 200SP system.
- Connector pins and signal terminals are critical for wiring diagrams. Review image details to confirm pinout configurations for your engineering documentation.

Inquiry Preparation
- Gather your project specifications regarding environmental conditions and temperature ranges. Include details about potential overload scenarios or thermal stress events in your request.
- Document the required input signal types for your control system. Specify whether you need 24 V incremental or pulse generator application context.
- Prepare technical drawings showing recorded space for the 7.8 cm width. Ensure your rack layout accommodates the T1 RAIL mounting standard.
- List any specific handling or review protocol questions for Siemens review contacts. Clarify requirements related to the product class B restriction in your submission.
Category Context
This module belongs to the broader SIPLUS extreme product line. It extends the capabilities of standard ET 200SP systems to harsh environments.
As an I/O Module, it interfaces directly with field devices. It processes digital inputs and counting signals for the central controller.
The RAIL technology enables modular expansion without complex wiring. Each module slides onto the carrier rail for quick installation and maintenance.
Review Notes
- The active lifecycle status confirms ongoing production and support review details. This ensures long-term sourcing options for project planning and maintenance needs.
- review restrictions apply due to the specialized nature of the product. Contact documented Siemens review contacts for handling procedures and technical assistance.
- Conformal coating adds durability but may affect heat dissipation slightly. Consider thermal management strategies when integrating multiple modules in enclosed spaces.
- Always verify the exact part number before submitting inquiries. The 6AG2138-6AA01-1BA0 designation is unique and should be referenced in all communications.
