Overview
The EX1200-4003 high-density matrix module allows the user to connect any input row to any output column, with a DPST relay at every row/column cross point. This architecture provides the framework for flexible switch system designs where multiple test instruments need to be connected to common test points.
The smallest building block is a (4 x 16) 2-wire matrix. Rows and columns can easily be expanded to form larger matrices. A (4 x 192) 2-wire matrix can be accommodated in an EX1200 series full rack mainframe. The two banks of matrices can be connected under program control to further simplify field wiring.
Relays capable of switching up to 250 volts and up to 2 amps are used to maximize the range of application spaces that can be addressed with this module. All relays are fail-safe to ensure that no undesired signals are present at the user interface in case of power interruption.
