Fuseprotected relay module with multiple channels This solid state relay module is available in 1, 2, 4, or 8 channel configurations and includes fuse protection to enhance safety in a variety of applications. Stable performance with low trigger current Designed to operate reliably under different conditions, it requires only a 2 mA trigger current, reducing the control signal load required from your system. Easy wiring with included connectors The module features 54 cm pins and blue KF301 terminal connectors to simplify installation and wiring, enabling quick and straightforward system setup. Clear perchannel status indicators Each channel has an LED indicator to show whether the relay is ON or OFF, providing easy monitoring during operation. Practical use scenarios Industrial control panels: switch multiple devices or subsystems with safety and quick diagnostics. Home or workshop automation: control lighting, fans, or other actuators from a microcontroller or automation hub. DIY robotics and test setups: reliably drive actuators or sensors while easily monitoring each channel's status.
