The Merlin MVXI1460 (E1460A) is a C-size, 1-slot VXI relay multiplexer delivering 64-channel switching capacity for high-density test applications. Built on register-based A16 slave architecture, this module employs latching armature relays to support multiple switching topologies—64 two-wire, 32 three-wire, 32 four-wire, or 128 single-ended latching relay channels—all configurable via QUIC terminal block without software modification. A direct replacement for the Keysight/Agilent/HP E1460A, it integrates into existing test systems.
