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.

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. A (4 x 768) 1-wire matrix can be accommodated in a 1U EX1200 mainframe.

The EX1200-4264 is a high-density matrix module which allows 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, sense and excitation channels from a digital multimeter, counter/timer, and digitizer can be connected to the input rows and 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 (2 x 32) 2-wire matrix, and rows of two banks can be joined together to create single (2 x 64) 2 wire matrix. A (2 x 348) 2-wire matrix can be accommodated in just 1U space, using an EX1200 series full rack mainframe. The two banks of matrices can be joined, as well as connected to the EX1200 DMM’s analog backplane bus to further simplify field wiring. 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.

The EX1200-4265 is a high-density matrix module which allows 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. It includes a bypass circuit which allows crossover connections that make this very ideal for cable test and characterization applications. Using this switch card along with necessary measurement instruments, users will be able to characterize cable voltage drop, timing (rise time, fall time), noise (differential, common mode, ground noise) as well as impedance, isolation and continuity, not just specific pin to pin, but any pin to any pin. 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.
