Information
This Harmony SSM solid state modular DIN rail single-phase relay is rated 12A, is controlled with a 4V to 32V DC input, has a rated load voltage of 24V to 280V AC with random voltage switching, ideal for inductive loads. It also has a visual indicator showing the status of its input. Built-in heatsink for maximum performance and less spare parts to manage. It is also silent and reliable thanks to the absence of moving contacts. Its clear schematic on the side of the socket enables easier wiring and maintenance. 0 0 0 0 0 0 0 0 0 0 0
