SWB-2811, 8x21, 1 A, Reed Relay Matrix Module for SwitchBlock
781421-11
8x21, 1 A, Reed Matrix Module for SwitchBlock - The SWB‑2811 is a reed relay matrix module for SwitchBlock systems. Designed for high power, it can operate as an individual relay card or expand in a single carrier or single PXI chassis. You can connect any input to any output, individually or in combination. You can use matrix switches to route signals from oscilloscopes, DMMs, arbitrary waveform generators, and power supplies to various test points on a unit under test (UUT). The primary benefit of matrix switches is simplified wiring—the overall test system can easily and dynamically change the internal connection path without any external manual intervention.
