The M221 (formerly Agilent E2273A) provides 8 independent non-latching SPDT switches with maskable interrupts that occur when the requested relay movements have been made. This M Module is useful when high integrity contacts are needed driving microwave relays located in your test adapter.

M Module Compliance

Complies with ANSI/VITA Std 12- 1996 for single-wide M Modules.

Data Transfers 16 bit

InterruptsINTC

Compatible with VXI, VME, PCI, PXI, CPCI & Ethernet Carriers

Applications

•LF Signal Switching

•Microwave relay control
