KNACRO New 8-way high-level solid state relay modules Blue Board DC 12V solid state relays 240V AC/2A Output with resistive fuse 240V/2A 50/60Hz high-level trigger With power anti-reverse function, then the wrong power supply will not damage the module. Output with 240V / 2A self returning fuse protection module security. It has four 3mm fixing bolt holes for easy installation. Genuine high-quality solid-state relay module, maximum load: AC 240V / 2A. Module anti-interference ability, stable performance, trigger current is only 1mA. Each relay has a status indicator (red). High-level control module, the module built-in current limiting resistor can be used directly positive voltage control, you can also use the microcontroller I / O control.
