Specification: Item Type: Delay Timer Relay Module Working Voltage: 12V DC, adaptable range (10V-16V) Working Current:: 50mA (static 5mA) Switching Capacity: 10A (0~250V AC or 0~30V DC) Output Form: A set of normally open + normally closed (ie dry contact) Input: The optocoupler completely isolates the input 1mA current, and the voltage above 2.0V can be driven. Do not keep the voltage for more than 20V for a long time. Signal Voltage Range: DC 3-30V Response Speed: 20mS (20ms) Delay Length: Adjustable from 0.2 seconds to 100 seconds. (Other time ranges can be set) Delay setting method: x10 shorted, x100 shorted indicates 1-10s range x10 shorted, x100 not shorted indicates 1-100s range x10 not shorted, x100 shorted to indicate 1-1000s range x10 shorted, x100 shorted indicates 1-10000s range Adjust potentiometer R4 at this time, adjust the time Package List: 1 x Delay Timer Relay Module
