● This module conform international safety standard, the isolation groove between control areas and load area
● With optical coupling isolation, triggering more reliable, more stable
● The double FR-4 circuit board design
● It has power and relay operation instructions.The LED will be lit when relay on
● Signal input with a high level signal, the common pin and the normally opened pin will connected
● Relay can directly control all kinds of equipment and load
● One normally open pin and a normally closed pin
● Blue KF301 terminal is more convenient
