National Instruments SCXI-1130 Matrix/Multiplexer Switch Module

The NI SCXI-1130 (Part Number: 778661-01) is a high-density Matrix/Multiplexer Switch Module with various configurations possible. It has 256 channels. This module is a great solution for systems with a huge or complicated channel count. The reed relays in this module are built to last for a long time. The SCXI 1130 operates at ten times the speed of standard armature relays, making the module a suitable front-end for high-speed measurement instruments like the PXI-4070 FlexDMM.

The SCXI-1130 module is completely software configurable to function as a multiplexer, matrix, or independent switch bank. This Matrix/Multiplexer Switch Module can be arranged in a few multiplexer configurations. The 1 and 2-wire modes are created for measuring or sourcing voltage or 2-wire resistance measurements. The 4-wire mode is best for the enhanced preciseness of resistance measurements. However, when the NI SCXI-1130 is arranged as a matrix, it turns into a general-purpose signal router. Expansion cables and plugs can be utilized to externally link the rows and columns of the matrix modules. As an example, to result in a 4x128 matrix, the user can link two SCXI-1378 Terminal Blocks with a matrix expansion cable. This doubles the quantity of columns. The device is equipped with 2 176-pin docking station plug I/O connectors, and has a maximum switching power of 10 W per channel.

When the SCXI 1130 module is configured with software as an independent switch bank, the user has the capability to control the state of all relays on the module. This mode can be employed for custom applications when the banks of 16x1 multiplexers can be joined to create different multiplexer sizes or function by themselves. The device has a maximum switching voltage, maximum current, maximum switching power of 60 VDC, 0.4 A, and 10 W respectively.

The NI device weighs 1.020 g, and measures 1.2 x 6.9 x 8.0 in. in physical dimensions. It has recommended operating and storage temperature range of 0 °C to 55 °C and –20 °C to 70 °C respectively, and a non-condensing relative humidity range of 5% to 85%.

SCXI-1130 Obsolete Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
