Dual 4 x 16 Two-wire Matrix, 250 V/2 A
|
Overview
The EX1200-4003 high-density matrix module allow the user to connect any input row to any output column, with a DPST relay at every row/column crosspoint. 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 digitizers can be connected to the input rows, and each of these devices 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 (4x16) 2-wire matrix, and rows and columns can easily be expanded to form larger matrices. A (4x192) 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 V and up to 2 A are used to maximize the range of application spaces that can be addressed with this module. All relays are failsafe which ensures that no undesired signals are present at the user interface in the case of power interruption.
