About A03B 1 Road 5v Low Level Solid State Relay Module With Fuse SSR 250V 2A Fuse
It is an 5V 240V solid state relay 2A, output with resistance type fuse 240V 2A. The input control signal voltage for the relay module is: (the state of the 0-2.5V low-level relay OFF; the state of the 3-5V high-level relay ON). Low-level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, make the relay, is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attracted. It has the blue KF301 terminal is connected to the line of control
Enhanced Safety with Integrated FuseEquipped with a built-in 2A fuse, this relay module offers an added layer of protection for your circuits and connected devices.

Wide Operating Temperature RangeEngineered for performance in demanding environments, the A03B relay module is reliable from -20C to +80C. This wide thermal tolerance makes it suitable for various industrial applications where temperature fluctuations are common.
Flexible Power and Easy IntegrationDesigned for versatility, the module accepts control voltages from 5V to 12V DC. The low-level trigger input and stereo interface simplify integration with microcontrollers and other automation systems, making installation straightforward even for complex setups.
FAQ's of A03B 1 Road 5v Low Level Solid State Relay Module With Fuse SSR 250V 2A Fuse:
Q: How do I connect the A03B 1 Road 5V Low Level Solid State Relay Module in my system?
A: To connect the module, use a 5V-12V DC power supply for input control and wire your AC load (up to 250V, 2A) through the output terminals. Ensure proper polarity and follow safety protocols during installation.
Q: What are the primary benefits of using this relay module in industrial applications?
A: This module provides electrically isolated switching for AC loads, safeguarding sensitive control electronics. The integrated fuse enhances safety by protecting against overloads, while its solid state design ensures quiet, reliable operation and long service life.
Q: When should I opt for a solid state relay over an electromechanical relay?
A: Solid state relays like the A03B are ideal when you need silent, fast switching and higher durability, especially in environments with frequent on/off cycles or where mechanical wear and tear is a concern.
Q: Where is the A03B relay module mainly used?
A: It is widely used in industrial automation, control panels, machinery, and other environments where reliable AC load switching is required under varying temperatures.
Q: What is the process for replacing the module's fuse?
A: If the built-in fuse blows, power off the system and carefully remove and replace the fuse according to the relay's specifications. Always use an identical fuse rating (2A) to maintain safety standards.
Q: Can this module be used outdoors, or in wet environments?
A: No, the A03B module is not waterproof (IP rating: not waterproof). It should be installed in a dry and protected indoor setting.
