4 x 128 One-wire Matrix, 150 V/0.5 Amp
|
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 one-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. A (4x512) 1-wire matrix can be accommodated
in only four slots of an EX1200 series mainframe, as an example.
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 failsafe which
ensures that no undesired signals are present at the user interface in the case
of power interruption.
