The E2271A is a single-wide, register-based M-Module. It contains 16 DPST latching relay switches organized as a 4 x 4 relay matrix. This allows for four sources and four destinations of two-wire switching to connect in any desired combinations. Therefore, it brings highly flexible matrix switching to your test system. Logic on the card provides for maskable interrupts (INTC type) once the requested relay movements are complete. The module also has a FIFO for storing up to 8 relay operations. You can write rapid setup changes to the module and execute them with only one interrupt occurrence once the entire group of relay movements is complete. You can use this M-Module to conveniently connect a group of instruments to several points on a device under test. A matrix module can be the center of a larger switching system, within the E2251A C-size carrier, with multiplexer and general purpose relays connecting multiple signals to the matrix.
