The Keysight / Agilent / HP E1460A High-Density Relay Multiplexer is a C-size, 1-slot, register-based VXI module. This 64-channel multiplexer, using latching armature switches, offers a highly configurable, high point-count switching topology. Switching topologies include 64 two-wire, 32 three-wire, 32 four-wire, or 128 single- ended latching relay channels. This multiplexer consists of a component card with switches (labeled E1460-66202) and the QUIC screw terminal block (E1460-80011) that plugs onto the component card.

Use of SCPI commands or status bit jumpers on the terminal card configures the E1460A "wire mode" as either a 128 x 1-wire, 64 x 2-wire, 32 x 3-wire, or 32 x 4-wire multiplexer.
