DC Motor Driver Module 5V 12V 24V 20A Forward Reverse Controller Self-locking Wide Voltage Drive Module Motor Limit Control Feature: 1. Copper terminal, strong overcurrent and low heating 2. The inputs are all optocoupler coupling, which is resistant to transient interference 3. 4V~40V input, DC voltage regulation, low power consumption and stable operation 4. Adopted of high quality electronic components, and accuracy process, for the durability 5. 20A relay, the product has strong load capacity Specification: Working Voltage: Wide Voltage 4.0V~40V (DC) Module Power Consumption: 0.6W (without load motor), Static 0.1W Signal Input: Active Low, The input is the negative of the optocoupler. a signal is considered to be present when the voltage is below 2V. Response Speed: K1 K2 is 20mS, SW1 SW2 is 50mS Output Current: 20A Operating Life: gt;150,000 times When the external CW (K1) is pressed, the motor will rotate CW, When K1 is released, the motor will stop running immediately Package List: 1 x Controller
