4-channel PLC amplifier boards built with high-quality components and precise manufacturing to ensure durability and long-term performance. The design maintains consistent functionality and reliability even in harsh environments. 4-channel MOSFET module supports output voltage from 3.7 to 27 V DC with up to 10 A per channel. This enables reliable handling of large loads and high power demands. PWM input control enables precise adjustment of motor speed and lamp brightness, allowing fine-tuning of power parameters to meet specific requirements and improve overall control of high-power devices. Versatile output connections can drive a wide range of high-power devices, including motors, incandescent lamps, LED strips, miniature water pumps, and solenoids; the module handles them flexibly and efficiently. Use scenarios: - Industrial automation: control DC motors and lighting for conveyors and automated equipment with a single compact module. - Robotics and automation projects: precise PWM motor control and load driving for actuators and lighting. - Fluid and valve systems: drive small pumps and solenoids for irrigation, cooling, or fluid handling with adjustable speed and brightness.
