This Harmony SSP solid state panel mount single-phase relay is rated 12A, is controlled with a 3.5V to 32V DC input, has a rated load voltage of 1V to 150V DC with DC switching. It has a visual indicator showing the status of its input and a alarm output enabling a quick response to unexpected events. It also has a test button for easy debugging, testing and commissioning. It is also silent and reliable thanks to the absence of moving contacts.
