External Trigger Delay Switch 12V Relay Module

1. Trigger Signal Source: High Level Trigger(3.0 V-24 V), signal ground and system groundare not common, which can increase anti-interference abilit system (short circuit can also connect with a ground common)
2. Output Capacity: can control no more than DC30V 5A AC or 220 V devices 5A
3. Optocoupler Isolation: improve the anti-interference ability, after the parameter setting,it will memory forever
