Solid State Relay Module 4 Channel – 5Vdc

Description

Product introduction: 1. This module conform international safety standard, the isolation groove between control areas and load area 2. With optical coupling isolation, triggering more reliable, more stable 3. The double FR-4 circuit board design 4. Have power and relay operation instructions.The LED will be lit when relay on 5. Signal input with a low level signal, the common pin and the normally opened pin will connected 6. Relay can directly control all kinds of equipment and load 7. One normally open pin and a normally closed pin 8. Blue KF301 terminal, more convenient 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 (Low 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 Quantity:1pc Package includes: 1 x 12V 1 Channel Low Level Trigger Relay Module
