The Agilent/Keysight E1466A is a C-size VXI relay matrix switch module designed for signal routing in automated test systems. This register-based, 1-slot module delivers a 4×64 two-wire switching matrix with independent high and low switching at each crosspoint. Built on latching armature relay technology, it minimizes power consumption while maintaining high reliability across large-scale switching applications.
Technical Specifications

– Key Features
• Expandability: Chain multiple modules using QUIC terminal block interconnections to scale row and column configurations. A full 13-slot VXI mainframe supports up to 3072 two-wire crosspoints. Four E1466A modules create a 4×256 matrix configuration.
• Modular Terminal Blocks: QUIC easy-to-use terminal blocks enable topology changes via block swap. The E1466A shares the same switch card with E1465A and E1467A modules—terminal block selection determines final matrix configuration.
• Channel List Management: Downloadable channel lists stored in onboard memory
• Firmware: Downloadable command module firmware
