The 40-183 supports 6 off high current SPST switches into two slots of PXI chassis. Each SPST switch uses a fully isolated solid state relay which has been designed to offer fast operation under hot switching conditions and high inrush current with no operational life degradation. Each SPST switch can support 30A of continuous current and switch up to 40V signals. The switch can sustain inrush currents in excess of 120A. AC or DC signals can be switched since the switch is polarity insensitive. Note: The 40-183-011 supersedes the 40-183-001 which is functionally the same but with some changes in specification. A data sheet for the 40-183-001 can be found in the 40-182/183 User Manual.
