Engineering Advantages

The 1734-SSI solves critical motion feedback challenges through specialized hardware architecture:

Elimination of Position Errors: The SSI protocol provides absolute position data without requiring a "home" sequence. The module maintains position integrity even after a power cycle, preventing machine crashes and reducing startup time.

Synchronous Data Transmission: The module synchronizes the clock and data signals, effectively eliminating transmission jitter. This provides the controller with stable, high-resolution feedback even in systems with rapid acceleration and deceleration.

Simplified DIN Rail Integration: The open-style, compact design snaps directly onto standard DIN rails. This reduces the footprint of the feedback system, allowing engineers to pack more functionality into smaller control cabinets.

Rapid Diagnostic Monitoring: Integrated status indicators provide real-time visual feedback on module power and communication health. This feature simplifies onsite troubleshooting, allowing technicians to identify signal faults without connecting external diagnostic tools.

FAQs

Does the 1734-SSI require a specific terminal base?

Yes. The 1734-SSI module requires a 1734 terminal base (such as the 1734-TB or 1734-TBS). Ensure you set the keyswitch to Position 2 before inserting the module to prevent hardware damage.

Can I use this module with an incremental encoder?

No. The 1734-SSI is specifically designed for absolute encoders using the Synchronous Serial Interface. For incremental encoders, you should select a high-speed counter module like the 1734-VHSC.

Is this unit a Brand New original product?

Yes. We guarantee this 1734-SSI is 100% Brand New in its original factory packaging. Using brand-new encoder modules is critical for ensuring timing components meet original precision tolerances.

How does the Little Endian format affect my programming?

The Little Endian format dictates the byte order of the incoming encoder data. Most modern Allen-Bradley controllers handle this format natively, simplifying the configuration of your tags and motion scaling.
