National Instruments 778572-34 PXI Matrix Switch Module
The National Instruments 778572-34 is a 1-Wire 8x32 PXI Matrix Switch Module which is also known as the PXI-2534. The 8x32 matrix means this unit has 8 rows and 32 columns. It features solid-state relays (SSRs) that ensure an unlimited mechanical lifetime and the capability to route 55 W across all channels at the same time. This module also includes onboard relay counting for efficient monitoring and supports deterministic operation with hardware triggers.
The NI 778572-34 is a 3U, one-slot PXI/cPCI module with dimensions of 21.6 x 2.0 x 13.0 cm and weighs only 238 grams. It requires 1 W at 3.3 V and 8 W at 5 V for power. The module has a 68-pin male SCSI connector and operates within a temperature range of 0 °C to 55 °C. It can be stored at temperatures between -40 °C and 70 °C and used at altitudes up to 2,000 meters above sea level.
The 778572-34 module offers a typical single crosspoint bandwidth of over 2 MHz in a 50 Ω system. It supports a maximum switching voltage of ±55 VDC or 30 VACrms and a maximum switching current of 1 A. The PXI matrix switch module can handle a maximum switching power of 55 W. The unit has a typical total path resistance of 1 Ω, with a maximum warranted resistance of 1.4 Ω. The 778572-34 offers an SSR operate time of 724 µs (typical) and 2.5 ms (maximum). This unit supports a maximum scan rate of 400 crosspoints per second and can drive up to 256 relays at the same time.
The 778572-34 unit accepts input from PXI trigger lines 0 to 7 with a minimum pulse width of 70 ns for triggering. The output trigger can be directed to PXI trigger lines 0 to 7, with a programmable pulse width that ranges from 1 µs to 62 µs. The module is compliant with various safety (IEC 61010-1, EN 61010-1, UL 61010-1, CSA C22.2 No. 61010-1) and EMC standards (EN 61326-1, EN 55022, ICES-001, etc.). You need to operate this unit with shielded cables only in order to ensure the mentioned EMC performance.
