National Instruments RM-4302 Terminal Block
The National Instruments RM-4302 (Part Number: 783872-01) Terminal Block is a multipurpose, industrial-grade tool for streamlining analog input connections in automation systems. This terminal block, which has 32 analog input channels with AI± differential input, allows accurate data collecting across a broad temperature range of 0°C to 55°C. With an offset voltage of 10 μV max at 23°C ±5°C and 4 μV typ at the same temperature, it ensures accurate measurements even in challenging environments.
The offset voltage stability, which is 0.5 μV/°C max and 0.05 μV/°C, ensures reliable operation at different temperatures. The external power input range supported by the RM-4302 Terminal Block is 6 VDC to 28 VDC, with a maximum current rating of 3.2 A. It has Positive Temperature Coefficient (PTC) resistor short circuit protection, which guarantees operating safety. Mechanically, the device has an RJ50 receptacle that is built to last—it can withstand up to 500 insertions before breaking. With a mechanical switch life of 5 × 10^7 cycles and an electrical switch life of 2 × 10^5 cycles, channel configuration switches that use electromechanical relays offer dependable performance. Connectivity options allow for flexible integration into a variety of industrial configurations.
These alternatives include 32 RJ50 connectors, one BNC, one 96-pin DIN, two COMBICON 2-position, and one COMBICON 4-position connector. The RM-4302 Terminal Block was designed with the environment in mind, guaranteeing dependable performance under a variety of circumstances. It functions in the 0°C to 55°C ambient temperature range with 10% to 90% relative humidity (non-condensing). It may be stored in environments between -40°C and 71°C and between 5% and 95% relative humidity. Adhering to strict shock and vibration regulations, the gadget can resist operational shocks up to 30 g in peak force as well as random vibrations between 5 and 500 Hz. It minimizes interference in industrial situations and complies with regulatory criteria for electromagnetic compatibility (EMC).
