The Agilent E2270A 16-Channel Form A Switch is a singlewide, register-based M-Module. It furnishes 16 independent SPST latching relays for general purpose signal switching and control of external devices. Use this M-Module when you need high integrity contacts or quality connections of nonmultiplexed signals in your system.
Logic on the card provides for maskable interrupts (INTC type) when the requested relay movements have been completed. The module also has a FIFO for storing up to eight 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.
With each M-Module having its own address within the E2250A and E2251A M-Module carriers, you have the flexibility to use the M-Modules in many combinations. This flexibility allows you to get the amount of functionality you need in smaller blocks, lowering your overall system costs.
