【Multifunction Timer Relay】Programmable delay modes to control the relay timings, widely used at smart home, industrial control, automatic irrigation, indoor ventilation, protection equipment etc..
【Load Range】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)..
【Reverse Protection】Built-in a diode to provide protection against accidental reverse polarity for the circuits..
【Sleep Mode】If no operation within 5 minutes, the digital tube of the relay board will turn off automatically. Pressing any button can wake it up..
【Parameter Setting】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..

Basic Function:When the piercing current exceeds the set value, the output switch will act Automatically reset when the piercing current is less than the set value..
Set threshold: set the threshold when the perforation current exceeds the threshold, the relay will work, and when the perforation current is lower than the threshold, the relay will reset.
Indicator light: the indicator light is off when there is no current, the green light is on when the current is lower than the threshold, and the red light is on when the current is higher than the threshold.
Delay adjustment: power-off delay can be set from 0 to 99 seconds, clockwise to increase and counter-clockwise to decrease.
Detection range: 0-50A, [email protected] AC/DC contact capacity.

photosensitive resistance module's most sensitive to ambient light, commonly used to detect environment around the brightness of the light, or MCU trigger relay module, etc..
module in the environment light intensity than set threshold, output high level DO end, when the environment light intensity more than set threshold, the DO output low level.
the DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect the environment light intensity change.
the DO output can be directly driven our relay module, which can form a light-operated switch..

【Fitment】Ignition Coil(traditional coil, double spark coil, single spark coil) generator, fan, electric-magnetic valves, emission gas controlling value, fuel injectors, relay. etc..
【Features】You can quickly and easily diagnose whether the ignition system of the car is working properly, avoid fire, and burn out the ignition coil. It provides a safe and reliable troubleshooting method that is convenient, economical and time-saving..
【Long-lasting】The Spark Tester is adopted to the high-quality aluminum material with high quality. The internal LED light will show you if the ignition system is normal. The ABS head is easy to insert and long-lasting, making it the right choice..
【Long-lasting】The car to be tested should park at an area with good air condition, can not suck into exhaust emission from engine. During test process, it is necessory to avoid the moving parts and heat source to protect tester and testing equipments..
【Good Performance】Excellent mechanical stability and corrosion protection. Professional manufacturing, high accuracy.
