For example, you can The NI PXI-2529, PXIe-2529, and SCXI-1129 are high-density matrix relay modules built for applications with high-channel counts. The modules are two-wire matrices that are configurable with front mounting terminal blocks to achieve many different matrix configurations. Table 1 provides a complete list of possible configurations. Expanding the matrix channel count is as easy as adding more modules. With the SCXI-1129, you can pass analog signals between two or more switch modules via a high-voltage backplane (HVAB), matrix expansion create an 8x32 two-wire matrix by using the NI SCXI-1335 terminal block with an SCXI-1129 module. You can easily transform the same SCXI-1129 module into a 16x16 two-wire matrix by simply replacing the SCXI-1335 with an NI SCXI-1336 terminal block. The NI 2529 modules use latching relays in the matrices to ensure that the state of each matrix remains unchanged in the event of accidental power loss. This feature prevents instruments and units under test from switching during cables, or matrix expansion plugs. Using these connections, you can instantly potentially damaging conditions. All relays open when power returns. expand your matrix without external wiring. The NI 2529 modules are designed Automatic Scanning to work well with both low- and high- voltage levels. They use relays with low thermal offset to ensure accurate low-voltage measurements. These relays can switch up to 150 Vrms or 150 VDC. the use of scanning. Scanning improves throughput by downloading a list of up to 32,000 connections to the switch and cycling through the list using an Matrix Operation The NI 2529 modules are general-purpose, two-wire matrices used to route differential event (trigger) without any interruption from the host processor. You can most efficiently implement scanning by mating an NI 2529 or SCXI-1129 with an instrument such as the NI PXI-4070 6½-digit FlexDMM, which issues a trigger signals. Through software, you can control after each measurement. the matrices to connect any row to any Safety Disconnect column. One of the key advantages of these modules is their adaptability to your switching needs. You can configure Figure 1. The matrix expansion plug simplifies expansion. NI 2529 modules can maximize throughput in automated test applications with the SCXI-1129 in six different matrix configurations and an NI 2529 in two The SCXI-1129 incorporates a safety interlock that disconnects the SCXI high-voltage analog bus from the matrix if the front terminal block is removed. This arrangement prevents potentially hazardous voltages from appearing on exposed front panel connector pins.

NI 2529 and SCXI-1129 Configuration and Matrix Expansion Expansion with the SCXI-1129 SCXI Analog Routing Matrix modules can serve as building blocks for creating configurations well You can increase the flexibility of your switch system with the addition of the beyond the size of a single module. Connecting the rows of two modules high-voltage analog bus (HVAB). Using the HVAB, you can easily route high- doubles the column count. Likewise, connecting the columns of two modules voltage or low-voltage analog signals between multiple switch modules or doubles the row count. For example, you can expand a 4x64 matrix, made up of instruments without the need for external wiring (assuming it is safe to do so). one SCXI-1129 module and one SCXI-1334 terminal block, to a 4x128, 4x192, For example, you can use the HVAB to effortlessly create a 4x256 matrix from 4x256, and so forth, by connecting the columns of multiple SCXI-1129 modules four SCXI-1129 modules in the 4x64 matrix configuration (SCXI-1334 terminal via the terminal block. To expand the columns of the SCXI-1129, you can use block). Without the HVAB, the 4x256 matrix requires external wiring or cables. expansion cables. Expansion cables connect four differential signals. Hence, The HVAB works with the SCXI-1127, SCXI-1128, and SCXI-1129 modules. you must use two matrix expansion cables for each expansion with the SCXI-1335 because it has eight rows. You can expand the row count of the SCXI-1129 with expansion plugs, which connect the columns of two adjacent switch modules as shown in Figure 1. With the expansion plugs, you can Signal Connections You can choose from several solutions for your signal connections: ■ for easy connections create the 128x16 matrix in less than five minutes.
