Keysight / Agilent / HP E1460A 64-Channel Relay Multiplexer (QUIC)

The Keysight E1460A is a 64-channel relay multiplexer module designed for signal routing in automated test systems. This C-size, 1-slot VXI module employs latching armature relays to deliver reliable signal integrity across diverse switching topologies. Configure it as a 128×1-wire, 64×2-wire, 32×3-wire, or 32×4-wire multiplexer via SCPI commands or status bit jumpers. The module scans at 75 channels/second and integrates with VXI systems through register-based control and analog bus interconnect. Eight banks of Hi/Lo switches, seven programmable control switches, and six wire jumper sets provide flexible common configurations for insulation testing and scanning voltmeter applications. The included QUIC screw terminal block simplifies field connections and reduces setup time.
