Industrial Relay for Low-Voltage Control

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.

Key Features

• Low-voltage coil options (e.g., 5V, 12V, 24V DC; 6V–24V AC variants available)
• Single-channel or multi-channel configurations
• Form C or Form A/B contact arrangements (NO/NC configurations)
• High-reliability contacts with fast, precise snap action
• High insulation voltage and good dielectric strength
• DIN-rail or panel-m mounting options for flexible installation
• Compact footprint suitable for crowded control panels
• Wide operating temperature range and rugged enclosure
• Isolation between coil and contacts for safety and EMI resistance
• Snubber-ready contacts for inductive loads
