This SSM modular relay is part of the range of Harmony solid state relays. It is rated 55A, is controlled with a 4 to 32Vdc input, has a rated load voltage of 48 to 660Vac with zero voltage switching, ideal for resistive loads. This static relay has a built-in heatsink for limited derating while limiting occupied space in panel. It mounts on 35mm DIN rails and comes with a secure mounting latch. It also has a visual indicator showing the status of its input. 0 0 0 0 0 0 0 0 0 0 0
