2 Channel Smart Dual Coil Latching Relay Board – 2 Channel Bistable Relay Module

2 Channel Smart Dual Coil Latching Relay Board – 2 Channel Bistable Relay Module

This is a Smart Dual Coil Latching Relay that can control the ON/OFF power of a device by applying a short voltage pulse to Input 1 and Input 2. This project is helpful in low-power applications since the coil is not powered all the time, it only requires a short voltage pulse. Relay...
