SWB-2813, 4x21, 1 A, 2-Wire Reed Matrix Module for SwitchBlock
781420-13
4x21, 1 A, 2-Wire Reed Matrix Module for SwitchBlock - The SWB‑2813 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.

PXI High Density Multiplexer: 99-ch, 2-Wire, 100Vrms/1A, Armature Relays
M9103A
The M9103A, a high-density, high-power 99-channel multiplexer routes many different channels to a single point. The switches operate in a break-before-make mode that ensures no two points are connected at the same time, or multiple channels can simultaneously connect if needed. This module is ideal for routing multiple analog signals to a measurement device in an automated test environment (ATE) or data acquisition systems. Each channel switch has a high and low for 2-wire switching. The high-quality armature relays are capable of switching up to 100Vrms, with up to 60W of power. Choose from the durable connector block or standard cable connections.
