National Instruments SCXI-1130

The National Instruments SCXI-1130 is a high-density Matrix/Multiplexer Switch Module designed to accommodate complex systems with extensive channel requirements, featuring a robust 256-channel capability. Utilizing reliable reed relay technology, the SCXI-1130 enhances durability and operates at speeds ten times faster than standard armature relays, positioning it as an optimal front-end for high-speed measurement instruments such as the PXI-4070 FlexDMM. The module is fully software-configurable to serve as a multiplexer, matrix, or independent switch bank, providing versatility in measurement applications.

It supports both 1 and 2-wire configurations for voltage or 2-wire resistance measurements, along with a 4-wire mode that ensures greater accuracy for resistance measurements. When configured as a matrix, the SCXI-1130 acts as a general-purpose signal router, with options to expand its capability using external matrix expansion cables and plugs, such as linking two SCXI-1378 Terminal Blocks to create a 4x128 matrix. The module features two 176-pin docking station plug I/O connectors and handles a maximum switching power of 10 W per channel.

In independent switch bank mode, users can control the state of all relays, enabling custom setups of multiplexers with varying sizes. The device accommodates a maximum switching voltage of 60 VDC, a maximum current of 0.4 A, and a maximum power rating of 10 W per channel. The SCXI-1130 measures 1.2 x 6.9 x 8.0 inches and weighs 1.020 g, with an operational temperature range of 0 °C to 55 °C and a storage range of -20 °C to 70 °C, maintaining functionality in a non-condensing relative humidity of 5% to 85%. Although the SCXI-1130 has been designated as obsolete, it remains available for purchase and repair services through Apex Waves.
