Description
Product introduction:
- 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
- Have 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, more convenient
- Module Size: 53x18x18.5mm/2.08*0.7*0.72
Module interface:
- Input Part:
- VCC: Connect to power positive (according to the relay voltage range)
- GND: Connect to power negative
- IN: Relay module trigger pin (high level trigger)
- Output Part:
- Normally Opened (NO) : Normally open pin of relay. NO pin is not connect to COM pin when relay off.NO pin is connect to COM pin when relay on
- Common pin (COM) : Common pin of the relay
- Normally closed (NC) : Normally close pin of relay.NC pin is connect to COM pin when relay off.NC pin is not connect to COM pin when relay on
- Onboard 12V, 10A/250VAC, 10A 30VDC relay
