Application: output port can control high power devices, such as motors, lamps, LED lamp strings, DC motors, micro water pumps, electromagnet valves; it can input PWM to control motor rotate speed and the brightness of lamp Interface: 1. DC+: device DC power positive 2. DC-: device DC power negative 3. PWM: signal input port (connects MCU IO ports, PLC interface, DC power) 4. GND: signal negative port 5. OUT+: output port positive (connects device positive) 6. OUT-: output port negative (connects device negative) Specifications: Model: YYNMOS-1 (input and output are completely isolated) Input Signal: 3-20V PWM signal Output Capacity: DC 3.7-27V, and the current is within 10A PWM Frequency: 0-20KHz Size: 3.7x2.3cm/1.46x0.91" Quantity: 1 Pc Note: Please allow 0-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
