HP E1344A 16-Channel T/C High-Voltage Relay Multiplexer

The HP E1344A Thermocouple Compensated High-Voltage 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 module consists of a B-size component card (labeled E1343-66201) and a screw terminal block that plugs onto the component card. The HP E1344A is functionally similar to the HP E1343A.

Using the HP E1326B or E1411B DMMs, the HP E1344A performs channel scanning with automatic conversions for many thermocouple types. Temperature measurements are made with automatic cold junction compensation. SCPI commands are also used to set up measurements. The card, in conjunction with HP VXI DMMs, also measures voltage, current, and two- and four-wire resistance.
