Industrial Relay for Low-Voltage Control

Reliable, compact relay designed for low-voltage control of industrial automation circuits. Features fast switching, durable contacts, and easy integration with DIN-rail or panel mounting for control panels and automation racks.

Description

The Industrial Relay for Low-Voltage Control is a versatile electromechanical relay engineered to control high-power loads from a low-voltage signal. Its robust contact set provides secure, repeatable switching with low contact wear and excellent snap action for fast response. Suitable for PLCs, sensors, and control circuits, this relay offers dependable performance in industrial environments. Depending on the variant, it supports coil voltages in 5–48 V DC or 6–24 V AC, and contact ratings appropriate for motors, heaters, and other common industrial loads. The compact enclosure, wide operating temperature range, and easy mounting options (DIN rail or panel) simplify integration into control panels, cabinet assemblies, and automation systems.
