Feature:1. Power-off delay disconnection, there is signal - ON, no signal - delay OFF.2. Double output contacts.3. Each channel maximum current is 5A.4. Adjustable time range 0-30/0-300 and time unit second/minute.5. Rotate the adjustable resistor to setup delay time.Specification:Item Type: Delay Off Relay ModuleVoltage: 12V DC (10-16V)Power Consumption: <1.0WOutput: Passive Output (dry contact), two sets of relay NO + NC output. Do not exceed 5A in each group.Life: 100,000 actionsInput: Voltage signal, valid signal above 1.5V, current needs at least 0.1mATerminalV+: Power supply +GND: Power supply -, also the reference GND for the signal voltageIN: Signal voltage input, low level below 1V, high level above 1.5V, and uncertainty in the middle. Withstands up to 30VNO1: Relay NO contact 1NC1: Relay NC contact 1COM1: Relay contact common terminal 1NO2: Relay NO contact 2NC2: Relay NC contact 2COM2: Relay contact common terminal 2Time Range Setting:When the selector switch is set to 30 position, it means that 0-30 is adjustableWhen the selector switch is set to the 300 position, it means that 0-300 is adjustableTime Value Adjustment:Turn the adjustable resistor counterclockwise to decrease the time and clockwise to increase the timeTime Unit Setting :When the selector switch is set to the Sec position, the unit is: secondWhen the selector switch is set to the Min position, the unit is: minuteExample:Requires a delay of 50 minutes:1. Set time range at 300 position2. Set time unit at Min position3. Adjust the adjustable resistor to the 50 position.Application: Use with limit switch and induction switch to achieve:1. Automatically close the door after timeout2. Assembly line product interruption monitoring3. Water/air flow interruption monitoring.Package List:1 x Delay Relay Module
