Lumel LU 001JDA244000 Solid State Relay, 3-32V DC Input, 240V/40A AC Output

The Lumel LU 001JDA244000 is a high-performance solid-state relay (SSR) engineered for the precise and reliable switching of AC loads in demanding industrial environments. By utilizing semiconductor technology, this device eliminates the mechanical wear associated with traditional relays, ensuring consistent performance and a significantly extended operational lifespan. It provides a robust solution for applications requiring frequent switching cycles and silent operation.

Advantages

The primary benefit of this solid-state relay is its ability to handle high-current loads with minimal control energy, thanks to its efficient 3-32V DC input range. Because it lacks moving parts, it is immune to contact bouncing and mechanical fatigue, which makes it exceptionally durable in high-vibration settings. Furthermore, the device offers rapid switching speeds and silent operation, which is essential for maintaining a quiet working environment in automated facilities.

Suitable for

• Industrial automation systems
• Heating element control
• Motor switching applications
• Lighting control systems
• Temperature regulation processes

When it may not be suitable

This solid-state relay is designed specifically for AC load switching and is not compatible with DC load applications. Additionally, it requires proper heat dissipation management; if installed in an environment without adequate ventilation or an appropriate heatsink, the device may overheat and fail prematurely.

Key specifications

• Control voltage: 3-32V DC
• Output voltage: 240V AC
• Maximum load current: 40A
• Switching type: Solid-state (semiconductor)
• Silent operation

How to use

To install the relay, connect the control signal wires to the DC input terminals, ensuring the polarity is observed according to the device markings. Connect the AC load in series with the output terminals of the relay. It is critical to mount the relay onto a suitable heatsink using thermal conductive paste to ensure efficient heat transfer, as the internal semiconductor generates heat during operation. Always verify that the load current does not exceed the rated 40A capacity to prevent damage.

What to consider before purchase

• Ensure the control signal voltage matches the 3-32V DC range.
• Verify that the load current does not exceed 40A.
• Confirm that the application involves an AC load.
• Check if an additional heatsink is required for your specific mounting environment.

Usage recommendations

Always install the relay in a well-ventilated area and use a properly sized heatsink to maintain optimal operating temperatures and ensure long-term reliability.
