The National Instruments RM-4304 Terminal Block (Part Number: 783873-01) is designed specifically for industrial automation applications, featuring 32 analog input channels that enable precise data acquisition across a broad temperature range of -55 °C to 55 °C. This terminal block ensures high accuracy in signal measurement, equipped with AI± differential input delivering a maximum offset voltage of 10 μV at 23 °C ±5 °C and a typical offset of 4 μV within the same range. It maintains exceptional offset voltage stability of 0.5 μV/°C maximum and 0.05 μV/°C for reliable operation at varying temperatures, while also providing an offset matching of just 2 μV between AI± and CAL± to enhance calibration accuracy.

Incorporating robust electromechanical relay switches, the RM-4304 offers a mechanical life expectancy of 5 × 10^7 cycles and an electrical life expectancy of 2 × 10^5 cycles, highlighting its durability and dependable performance in demanding environments. Connectivity is versatile with multiple interfaces, including RJ50 receptacles, BNC, 96-pin DIN, and COMBICON slots, allowing for seamless integration into various industrial automation setups. With a high tolerance for harsh operating conditions, the RM-4304 can function effectively at altitudes up to 2,000 meters, withstand shocks of up to 30 g peak half-sine with an 11 ms pulse, and endure random vibrations of 0.3 g rms while operating, and 2.4 g rms when not operating. The terminal block maintains compliance with EMC regulations, providing protection against electromagnetic interference, and is designed to operate in noncondensing environments within a relative humidity range of 10% to 90%. Additionally, it can be safely stored at temperatures between -40 °C and 71 °C, ensuring versatility and resilience for various industrial applications.
