Pickering introduces high-current switches
-- Test & Measurement World, 11/1/2008 2:00:00 AM
Pickering Interfaces has expanded its range of PXI high-current switching products with the introduction of a family of high-power solid-state relays. The range comprises eight modules configured as fault-insertion, SPST (single-pole, single-throw) relay, multiplexer, and matrix switches capable of handling 10 A at 200 V and 30 A at 40 V. Each unit occupies two slots in a 3U chassis.
The 40-192 is a six-channel fault-insertion switch with two fault buses capable of hot-switching signals up to 10 A and 200 V. The 40-191 uses the same architecture, but is capable of switching signals of 30 A and 40 V and handling surge currents in excess of 120 A with no lifetime degradation. Each module can simulate most common faults found in a system, including open circuits and short circuits to one of two fault connections.
The other models in the family are the 40-182 and 40-183 six-channel SPST solid-state relay switches; the 40-666 and 40-667 solid-state multiplexers, which are available in dual three-channel or single six-channel configurations; and the 40-553 and 40-554 6X2 solid-state matrices.
