6ES7138-4HA00-0AB0

Product Description

It provides 2 analog inputs for voltage or current signals, with a resolution of 9 bits for voltage (0 to 10 V) and 10 bits for current (4 to 20 mA). This module is designed for high-speed signal acquisition, featuring a conversion time of less than 1 ms per channel, making it suitable for fast control loops and real-time monitoring applications. The module is housed in a compact design that fits directly onto the ET 200S terminal block, ensuring easy installation and replacement without disconnecting field wiring. This module supports a wide range of input signals, including unipolar voltage (0 to 10 V) and current (4 to 20 mA), with programmable diagnostics and parameter assignment via the ET 200S interface module. It operates with a supply voltage of 24 V DC (via the terminal block) and provides electrical isolation between the channels and the backplane bus, enhancing signal integrity and system reliability. The module is compatible with SIMATIC S7-300, S7-400, and other PROFIBUS DP masters when used with an appropriate ET 200S interface module (e.g., IM151-1). The 6ES7138-4HA00-0AB0 is a genuine Siemens product, manufactured under strict quality standards, ensuring long-term durability and performance. It is commonly used in automotive, food and beverage, pharmaceutical, and material handling industries where precise analog signal acquisition is critical. With its fast conversion time and robust design, this module is an ideal choice for upgrading or expanding existing ET 200S installations. As a new original spare part, it comes with a full manufacturer warranty and is available for immediate shipment. The Siemens 6ES7138-4HA00-0AB0 is an analog electronic module for the ET 200S distributed I/O system.

Technical Specifications

Version & Model Difference

The 6ES7138-4HA00-0AB0 is a specific version of the ET 200S analog input module. Earlier versions (e.g., 6ES7138-4HA00-0AB0) may have had different firmware or hardware revisions. The current version (as of 2026) supports high-speed conversion and is fully compatible with the latest ET 200S interface modules (e.g., IM151-1, IM151-3). There are no major functional differences between the standard 2 AI U/I module (6ES7134-4FB01-0AB0) and this high-speed variant, except for the faster conversion time and slightly lower resolution. Always check the product label for the exact version and ensure compatibility with your existing system configuration.

Application Scenarios

• What is the difference between the 6ES7138-4HA00-0AB0 and the standard 2 AI U/I module (6ES7134-4FB01-0AB0)?

The 6ES7138-4HA00-0AB0 is a high-speed variant with a conversion time of less than 1 ms per channel, whereas the standard module has a conversion time of about 3 ms. The high-speed module also has a slightly lower resolution (9/10 bits vs. 12 bits) but is optimized for fast control loops. Both modules are electrically and mechanically compatible with the ET 200S system.
