ACEIRMC DC 6-30V Timer Relay Programmable Delay Relay Module Cycle Timer with LCD Display / 5V Micro USB, Smart Home Controller (10pcs)

About this item

• Programmable delay modes to control the relay timings, widely used at smart home, industrial control, automatic irrigation, indoor ventilation, protection equipment etc.
• Operating voltage: DC 6V - 30V, support micro USB 5V power supply. High level trigger: 3V - 24V. NO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Timing range: 0.1s ~ 999mins (continuously adjustable).
• Built-in a diode to provide protection against accidental reverse polarity for the circuits.
• 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.
