The Control Unit Adapter,  6SL3040-0PA01-0AA0, is a versatile and reliable device that plays a critical role in various industrial control applications. This data sheet provides comprehensive technical information about the adapter, empowering engineers and users to make informed decisions regarding its integration into their systems.

Electrical Data:

The Control Unit Adapter operates on a 24 V DC power supply and consumes a maximum current of 0.65 A, making it energy-efficient. The device supports a conductor cross-section of up to 2.5 mm² (AWG 14), allowing for robust connections. With a maximum power loss of 2.6 W, the adapter ensures minimal energy wastage during operation. The PE connection utilizes an M4 screw, providing a secure and reliable grounding point.

On-board Encoder Interface:

One of the key features of the Control Unit Adapter is its built-in encoder interface. The device offers the flexibility to evaluate both incremental and absolute encoders. For incremental encoders, users have the option to choose between TTL/HTL encoders, providing compatibility with various encoder types. The input current for TTL and HTL encoders ranges from 2 mA to 10 mA. The encoder supply can handle a maximum load current of 0.35 A at 24 V and 5 V respectively. With a maximum encoder frequency of 500 Hz and an SSI baud rate ranging from 100 to 250 kBaud, the adapter ensures accurate and precise encoder data processing. The SSI absolute position resolution of 30 bits enhances the adapter's ability to handle complex positioning tasks.

Cable Length and Mechanical Data:

The Control Unit Adapter supports extended cable lengths, enabling flexible placement in industrial setups. For TTL and SSI encoders, the maximum cable length is 100 meters (328.08 feet), while HTL encoders with unipolar signals can be extended up to 100 meters as well. For HTL encoders with bipolar signals, the cable length can be extended up to 300 meters (984.25 feet), allowing for extended reach in large-scale applications. With a net weight of 0.32 kg (0.71 lb) and compact dimensions of 73 mm (width) x 165.8 mm (height) x 37.3 mm (depth), the Control Unit Adapter offers a space-saving and lightweight solution for control system integration.

Standards and Certifications:

The Control Unit Adapter complies with safety standards and holds a Certificate of Suitability cULus, ensuring its reliability and adherence to industry guidelines. This certification reassures users of the adapter's safety and quality.


The Control Unit Adapter, Article No. 6SL3040-0PA01-0AA0, is a high-performance and feature-rich device that offers excellent control capabilities for industrial applications. With its flexible encoder interface, extended cable length support, and compact design, this adapter presents an efficient and reliable solution for precision control tasks. The device's compliance with safety standards and certifications ensures that it meets industry requirements and guarantees the utmost safety and performance in industrial settings.
