HP E1347A VXI 16-Channel Thermocouple Compensation, Low-Offset Relay Multiplexer |
The HP E1347A general-purpose reed relay multiplexer is a B-size, 1-slot, register-based VXI module with thermocouple compensation. It switches 16 channels of high, low, and guard each. The module has low thermal offset performance. The multiplexer module consists of a B-size component card (labeled E1345-66201) and a screw terminal block that plugs onto the component card. The HP E1347A is functionally similar to the HP E1345A.
Using the HP E1326B or HP E1411B DMMs, the HP E1347A performs channel scanning with automatic conversions for many thermocouple types. Temperature measurements are made with automatic cold junction compensation. The card, in conjunction with HP VXI DMMs, also measure voltage, current, and 2- and 4-wire ohms.
C-size Adapter
For installing the HP E1347A in a C-size mainframe, the HP E1403B
active adapter is recommended.
Note: Configuration software that allows you to easily select
compatible interfaces, controller platforms, and VXI test system
components is available on CD ROM. Order the
"Test System
and VXI Products Catalog and CD ROM" from
the Test & Measurement Catalogs available on this web site.
