You can switch loads up to DC 5-36V/15A with this module. It operates like a relay board. Supports PWM input for proportional control (i.e DC motor speed control).
Technical specifications:
Operating voltage: DC 5-36V
Trigger source: Digital high-low (DC3.3V-20V) (can be connected IO port of microcontroller, PLC interfaces, DC power, etc. The module can access PWM signal, which can perfectly supported the frequency of 0-20KHZ)
