PXI solid state multiplexer speeds up test process

A 5A PXI Solid State Multiplexer has been launched by Pickering Interfaces at IEEE Autotestcon in Maryland (November 2-5). This multiplexer (model 40-652) was originally designed for a large defence contractor looking for a multiplexer that could handle large inrush currents. The 40-652 MUX series offers a range of configurations suitable for hot or cold switching signals up to ±100V at 5A.

The use of solid state relays allows the hot switching of signals without any life degradation, including DC signals that EMR (Electro-Mechanical Relay) designs can only handle with much-reduced service life and power handling.

The design is capable of switching inductive loads up to a stored energy of 20mJ and is capable of withstanding 30A inrush currents for 300 µs when switching capacitive loads. The multiplexer module is available in single pole 48:1, two pole 24:1, single pole dual 24:1 or single pole 24:1 configurations.

The use of solid state relays also ensures a fast, typical operating time of 85us making it ideal for use in applications where the speed of test is critical. This range is also supported by Pickering Interfaces eBIRST switching system test tools; these tools provide an easy to use solution for quickly identify faulty switching systems.

Pickering Interfaces offers a standard three-year warranty and guaranteed long-term product support.

Pickering will also showcase the multiplexer at productronica 2015 in Munich (November 10 – 13).
