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. For example, a digital multimeter, counter/timer, and digitizer can be connected to the input rows and then each device can be connected to any of the output columns depending on the measurement function that is desired during the test. The connections between rows and columns occur internal to the module which greatly reduces external cabling.
The smallest building block is a (4 x 16) 2-wire matrix and 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. Relays capable of switching up to 300 V and up to 2 A are used to maximize the range of application spaces that can be addressed with this module.
