The IXYS PAA190STR is a two-channel solid state relay on a PCB mount. This relay has a form A contact configuration, a higher voltage rating of up to 400 V, and is rated for a current of up to 150 mA. It features a zero-crossing on-off control, meaning that the relay has a delay between the power being switched off and the output of the relay being switched off, which makes it suitable for use with sensitive electrical devices. The PAA190STR has LED light indicators to show when the relay is in the on or off state. It is used in a wide variety of applications, including switching audio and video signals, HVAC systems, motor control, and more.
