The device operates with two relays, where relay 1 turns off after N seconds, followed by relay 2, creating a continuous cycle.Upon power activation, both relays remain inactive until a signal or button trigger occurs, initiating the relay sequence.It supports NPN signal sensors, allowing for customizable relay monitoring based on programmed signals.The system can control a motor to rotate forward or backward based on the received signals, enhancing operational flexibility.The device is designed for efficient timing control, enabling precise management of relay actions and motor functions.This product is designed to provide reliable control over two relays, allowing for timed operations and signal-based triggers. With the ability to program signals for customized relay monitoring, it ensures flexibility in various applications. The NPN signal sensor compatibility enhances its functionality, making it suitable for diverse operational needs. The motor control feature allows for forward and backward rotation, providing versatility in usage. Ideal for automation projects, this device simplifies complex control tasks while maintaining efficiency.Color: As ShownMaterial: plasticPackage Contents:Package Contents:1 * Industrial Control Board1 * housingOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
