National Instruments / Smart E Tech RTI-12344 Rear Transition Interface
The RTI-12344 (Part Numbers: 785376-01 (NI), 93342 (Smart E Tech)) is a Rear Transition Interface that bridges 16 analog input/output (AI/AO) channels on a Level 1-compliant SLSC card to a 37-pin DSUB connector, popular with cRIO modules like the NI9264 or NI9220. The interface allows for standardized transmission of signals between SLSC chassis-based systems and measurement hardware from National Instruments, thereby enabling easy integration into industrial automation and test systems.
As an integral member of the SLSC platform, RTI-12344 completes the signal chain between cRIO or PXI systems and the device under testing (DUT). It has support for up to 60VDC voltage levels on its XP3 and JR1 connectors with an upper limit of 8A per contact at the temperature of 30°C. It has an XP2 rated for up to 1A per contact for the safe transmission of the analog type as it is compatible with shielded cables for electromagnetic compatibility (EMC). Pinout in the module assigns SLSC card ports (P0-P3) on the 37-pin DSUB connector, giving proper channel alignment for applications requiring analog signal conditioning or data acquisition.
The RTI-12344 was developed for laboratory and industrial applications, operating efficiently in a temperature range from 0°C to 80°C and at altitudes of up to 2000 meters. The compact dimensions (101.9mm x 30.2mm) allow easy integration into SLSC chassis rear panels, and installation by screws ensures mechanical stability. The interface supports modular expansion for multi-stage signal conditioning by connecting multiple SLSC cards in sequence.
Designed for compatibility, the RTI-12344 complies with the National Instruments-specified connector and pinout specifications, thereby making integration with commercially available NI hardware straightforward. This design obviates custom cabling in the majority of applications, thereby minimizing deployment time and complexity. It is used in automated test systems, industrial control systems, and research setups that demand high-density analog routing of signals. Standardizing the interface between SLSC cards and cRIO modules, the RTI-12344 improves system scalability without any compromise on signal integrity under severe operating conditions.
