HP E8460A 256-Channel Relay Multiplexer

The HP E8460A High-Density Reed Relay Multiplexer is a C-size, 1-slot, register- based VXI module. This 256 - channel multiplexer, using reed relay switches, offers a fast, reconfigurable, high point-count switching topology. It is designed for applications requiring fast scanning rates by the use of fast action reed relays. This single-slot multiplexer extends the choices of multiplexers available to the system engineer.

The HP E8460A can be programmed into individual topologies; some common examples are shown in the table below. Many other combinations of these topologies are supported (in addition to those shown in the table). two-wire, three-wire, and four-wire measurements can be configured.
