The National Instruments RTI-12302 Rear Transition Interface is designed for seamless integration with the Switch Load and Signal Conditioning (SLSC) architecture, optimizing communication between National Instruments' PXI or cRIO platforms and traditional measurement instruments. Serving as a vital link for digital input/output transactions, the RTI-12302 facilitates reliable signal passage through its rear-mounted interface within SLSC cabinets. The device accommodates up to 64 digital I/O channels via two VHDCI connectors, JR2 and JR3, specifically allocated for Port 0 signals (P0.0 to P0.63), complemented by grounding connections. Additionally, it features connectors XP2 and XP3, which support mixed signal and power functions; XP2 is rated for up to 30VDC at 0.3A per contact, while XP3 and JR1 can handle higher currents of 8A per contact at 60VDC, thereby ensuring effective power delivery to connected peripherals.

Engineered to endure rigorous laboratory and industrial conditions, the RTI-12302 operates effectively between 0°C and 80°C and within 10–90% non-condensing humidity. Its compact design (101.9mm x 30.2mm) is tailored to fit SLSC form factors, while electromagnetic compatibility is enhanced through the use of shielded cabling to mitigate interference in commercial settings. Safety-oriented design guarantees compliance with relevant standards to prevent use in explosive or hazardous environments, addressing voltage regulations to avert electric shock risks.

The RTI-12302 promotes straightforward system integration, adhering to National Instruments' connector specifications for plug-and-play compatibility with SLSC cards, PXI modules, and cRIO systems. It is ideal for applications in automated test systems, signal conditioning workflows, and multi-step signal processing setups, ensuring reliable digital I/O interfacing. Furthermore, the RTI-12302 allows for future expansion through SLSC modular arrangements, making it a versatile solution for diverse automation needs. Custom RTI solutions from SET GmbH offer added flexibility, though the RTI-12302 meets the generic requirements for DIO 64 RDIO2 implementations with precision engineering and established industry interoperability.
