Features: 1.Multifunction: Timer relay with delayed closing, delayed disconnection, self locking and trigger delay function. 2.Anti Reversal Function: Relay module has the power supply anti reversal function, reverse power supply will not damage the module. 3.Timing Duration: The parameters can be saved, and the setting content will not be lost when power is lost. Timer duration can be set from 0.1sec to 120sec. 4.PCB Material: Timer relay module is made of PCB material, which is not deformed for long time use, thus ensuring the stability for a long time. 5.Easy to Install: Light weight, easy to carry. Timer relay is small in size, light in weight, easy to install, easy to use, easy to use and stable in performance. specification:Item Type: Time Delay Relay Module Material: PCB Operating Voltage: DC 5V, 12V, 24V Three Optional (Should Not Exceed +/-10% of the Nominal Voltage) Operating Current: Less Than 80mA at 5V (Less Than 1ma when the Relay is Not Operating) Less Than 35mA at 12V (Less Than 1ma when the Relay is Not Operating) Less Than 18mA at 24V (Less Than 1ma when the Relay is Not Operating) Operating Temperature: Recommended -20 to 60 (Limit Range -30 to 70) Load Capacity.
