2. Trigger Signal Source: High Level Trigger (3.0 V-24 V), signal ground and system ground are not common, which can increase anti-interference abilit system (short circuit can also connect with a ground common)
3. Output Capacity: can control no more than DC 30V 5A AC or 220 V devices 5A
4. Optocoupler Isolation: improve the anti-interference ability, after the parameter setting, it will memory forever
Warning: Relay contact is passive and electricity production; 1 channel has the control function on / off
