Relay Module 2-Channel 5V/12V/24V - Programmable Cycle Timer Board with LED Display and Self-Lock Function for Smart Home, Automation Control(12V)

SpecificationItem Type: Time Delay RelayModel: FRM02Color: RedVoltage: 12VBoard Size: 77*50mm(3.03*1.97in)Mounting Hole Spacing: 70*43mm(2.76*1.69in)Hole Diameter: 3.5mm(0.14in)Module Control Terminal: There is a 3-wire interface, all interfaces have wiring terminals, which is convenient for users to use1. DC+: DC power supply positive (12V modules are available)2. DC-: negative pole of DC power supply3. CH1: Input detection interface 1, active at high level3. CH2: Input detection interface 2, active at high levelRelay Output Terminal: 6-wire interface, all interfaces have wiring terminals1. NO1: Relay normally open interface 1, hang in the air before the relay is closed, and short-circuit with COM1 after it is closed2. COM1: Relay common interface 13. NC1: Relay normally closed interface 1, short-circuit with COM1 before the relay is closed, and hang in the air after being closed4. NO2: Relay normally open interface 2, hang in the air before the relay is closed, and short-circuit with COM2 after it is closed5. COM2: Relay common interface 26. NC2: Relay normally closed interface 2, short-circuit with COM2 before the relay is closed, and hang in the air after being closedLoad Capacity: Maximum load capacity of normally open port: DC 0-30V/10A, AC 0-250V/10AMaximum load capacity of normally closed ports: DC 0-28V/10A, AC 0-125V/10APackage List1 x Time Delay RelayNoteFunction 1-8 starts automatically when it is powered on. Function 9-18 needs a high-level pulse signal (high-level duration is not less than 20ms, the same below) to trigger the start, and function 19-20 needs a continuous high level
