5V 30A 1-Channel Relay Module – High Power Relay Board with NO/NC/COM Terminals

5V 30A 1-Channel Relay Module is a high-power electromechanical relay board designed for controlling AC and DC loads using Arduino, microcontrollers, PLCs, and other control systems. It uses an SLA-05VDC-SL-C relay with NO, COM, and NC contact terminals. The module provides a simple DC+, DC− and IN control interface and is suitable for switching high-current electrical loads. The relay itself is rated up to 30A, with commonly specified contact ratings of 250V AC / 30V DC.

Key Features:

• 1-channel relay module
