Overview
The EX1200-4128 is an ultra high-density matrix module that allows the user to connect any input row to any output column, with an SPST 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. The 1-wire architecture allows for any of the 128 row inputs to be connected to any of the 4 column outputs.
The four output columns can be routed to the EX1200 series internal analog backplane to build large matrices or to connect to the optional 6.5 digit DMM, which also limits the amount of external cabling required. For example, a (4 x 512) 1-wire matrix can be accommodated in only 4 slots of an EX1200 series mainframe.
Stub-breaking relays can remove a matrix module from the backplane to increase signal integrity of measurements being made on other modules. All relays are fail-safe, which ensures that no undesired signals are present at the user interface in case of power interruption.
