Youmile Timer Delay Relay Module DC 6 30V Programmable Switch Control LED Display Micro USB Port for Arduino with 24AWG Wire, Cable

Operating voltage: DC 6V - 30V, support micro USB 5V power supply. High level trigger: 3V - 24V; Built-in a diode to provide protection against accidental reverse polarity for the circuits. NO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Timing range: 0.1s ~ 999mins (continuously adjustable); If no operation within 5 minutes, the digital tube of the relay board will turn off automatically. Pressing any button can wake it up. OP(conduction time) / CL(off time) / LOP(circuit times) can be set individually, and the parameters are mutually independent. All parameters are permanently saved once set. The functions and parameters can be reviewed or changed at a later time. Widely used for smart home, industrial control, automatic irrigation, indoor ventilation, protection equipment etc. User's manual:https://bit.ly/2YrfL8a Package Content:1 x DC6-30V Timer Delay Relay Module, 1 x 19.6" 24AWG Wire, 1 x Micro USB Cable
