The National Instruments RTI-12344 Rear Transition Interface is designed to facilitate seamless connectivity between Level 1-compliant SLSC cards and measurement hardware, particularly for applications requiring high-density analog routing. This component bridges 16 analog input/output (AI/AO) channels to a 37-pin DSUB connector, ensuring compatibility with cRIO modules such as the NI9264 and NI9220. Capable of supporting voltage levels up to 60VDC on both the XP3 and JR1 connectors, the RTI-12344 allows a maximum current of 8A per contact at an ambient temperature of 30°C. The XP2 connector is rated for 1A per contact, optimized for safe analog signal transmission and designed for use with shielded cables to maintain electromagnetic compatibility (EMC).

As part of the SLSC platform, this interface effectively completes the signal chain between PXI or cRIO systems and the device under test (DUT), supporting modular expansion and enabling connections of multiple SLSC cards for multi-stage signal conditioning. The RTI-12344 operates efficiently within a temperature range of 0°C to 80°C and altitudes up to 2000 meters. Its compact dimensions of 101.9mm x 30.2mm allow easy installation in SLSC chassis rear panels, providing mechanical stability through screw installation. The interface meets National Instruments' specified connector and pinout standards, simplifying integration with existing NI hardware, minimizing the need for custom cabling, and reducing deployment time. Ideal for automated test systems, industrial control environments, and research applications, the RTI-12344 enhances system scalability while ensuring signal integrity across varied operating conditions.
