HP E1345A VXI 16-Channel General Purpose, Low Offset Relay Multiplexer


[ Summary ][ Features ][ Specifications ][ Ordering ][ Assistance ]

Product Summary

The HP E1345A general-purpose reed relay multiplexer is a B-size, 1-slot, register-based VXI module that switches 16 channels of high, low, and guard each. The multiplexer has low thermal offset performance. This module consists of a B-size component card (labeled E1345-66201) and a screw terminal block that plugs onto the component card. The HP E1345A is functionally similar to the HP E1355A and E1356A.

The HP E1345A multiplexer is arranged into two banks of eight switches, each having its own common high, low, and guard screw terminals accessible on the terminal block. Tree-switched common high, low, and guard screw terminals and analog bus connections provide access to all 16 channels. The module may be programmed as either a single 1x16 3-wire multiplexer, two independent 1x8 3-wire multiplexers (for 4-wire Ohm), or a 1x8 6-wire multiplexer.

C-size Adapter
For installing the HP E1345A in a C-size mainframe, the HP E1403B active adapter is recommended.
