Description

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 48V to 600V AC with zero voltage switching, ideal for resistive 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.

Features

Silent and reliable due to the absence of moving contacts
Resistant to shocks, vibration and pollution, which makes it ideal for harsh industrial environments
Unlimited electrical endurance: reduce your maintenance and downtime costs
Visual indicator LED for a simpler troubleshooting and commissioning
Clear schematic on the side of the socket, for easier wiring and maintenance
