Dold BF9250 Series Solid State Relay, 10 A Load, Top Hat Rail Mount, 280 V Load, 48V Control BF9250

Dold BF9250 Series Solid State Relay BF9250 is a semiconductor contactor designed for silent and wear-free switching of AC loads, including heating elements, motors, valves, and lighting applications. It offers a maximum load current capacity of 10 A and supports load voltages up to 280 V with a minimum load voltage of 24V DC, making it suitable for a variety of industrial and automation environments.

The relay features a top hat rail mount design, allowing easy installation in control panels with cage clamp terminal connections ensuring secure and durable wiring. Its compact dimensions (85mm length, 22.5mm height, and 120mm width) make it suitable for densely packed assemblies.

Operating temperature ranges from 0°C to 40°C and protection ratings IP40 and IP20 provide reliability in industrial settings. The relay incorporates zero-voltage switching technology, preventing feedback into the main power grid and significantly reducing electrical noise.

An integrated temperature monitoring system with three LED indicators protects the device from damage due to excessive current by enabling immediate fault detection. It also features a protection circuit with varistors and a memory-preserving semiconductor output for enhanced durability and performance over long operational cycles.

The control input operates with low power consumption (minimum control voltage 3V, maximum 48V), making it ideal for PLC-based control systems. Its design complies with EN 60 947-4-2, IEC 60 158-2, and VDE 0660 part 109 standards, ensuring safety and reliability in industrial applications.

This Solid State Relay is commonly used in manufacturing automation, HVAC control systems, water treatment plants, and laboratory instrumentation where silent, rapid, and frequent switching of AC loads is needed.
