The National Instruments / Smart E Tech RTI-12304 Rear Transition Interface is a purpose-built solution for integrating with SLSC (Switch Load and Signal Conditioning) chassis, facilitating a seamless interface between industrial equipment and measurement systems. This module is equipped with a 37-pin D-subminiature connector, adhering to the specifications of the SLSC architecture and current industry measurement standards for secure signal and power transmission. Installed at the rear of the SLSC chassis, the RTI-12304 enables direct connection between the backplane and SLSC cards, as well as between SLSC modules and external systems such as PXI or cRIO devices.

The RTI-12304 supports a variety of digital I/O applications, catering to a maximum voltage of 60VDC across its connectors. Specifically, the XP2 connector allows for 0.5A per contact, ideal for standard signal lines, while XP3 and JR1 connectors accommodate higher current demands of up to 8A per contact. The pinout configuration includes digital signal routing ports (P0-P3), ground connections (GND), and no-connection points (NC), ensuring reliable signal integrity for diverse industrial automation requirements.

Designed to operate in challenging environments, the module functions effectively between 0°C and 80°C and can withstand relative humidity levels up to 90% (non-condensing). Its electromagnetic compatibility is enhanced through the use of shielded cables, significantly minimizing interference in mixed-signal applications. Safety features incorporate voltage limitations of 60VDC and installation practices that mitigate electricity-related hazards.

As an integral part of the SLSC infrastructure, the RTI-12304 streamlines the integration of switch and signal conditioning modules within scalable test systems, reducing the need for custom configurations while maintaining interoperability with NI hardware and software ecosystems, including LabVIEW. This versatility positions the RTI-12304 as an essential component for data acquisition, automated testing, and multi-stage signal conditioning, thus ensuring reliable interfacing for engineers working with measurement devices and test units. The module exemplifies SET GmbH's commitment to providing adaptable, module-based solutions addressing evolving needs in industrial automation.
