The Keysight E1463A is a C-size VXI switch module that delivers 32 channels of Form C relay switching in a single-slot mainframe configuration. Engineered for automated test systems demanding high current capacity and reliable signal routing, each channel handles up to 5 A at 125 V. The register-based architecture employs non-latching relays with typical thermal offset voltage below 3 µV, making it well-suited for signal switching, scanning, and control applications across process automation, appliance testing, and on/off switching scenarios.

– Compatibility & Integration
The E1463A integrates into any VXIbus-compliant mainframe via standard VXIbus protocol. Programming is supported through SCPI (Standard Commands for Programmable Instruments), with VXIplug&play drivers available for rapid system integration. Relay life depends on switching frequency, load type (resistive vs. capacitive/inductive), and inrush current magnitude.
