Features 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 Module Power Consumption: <1.0W Output: Passive Output (dry contact), two sets of relay NO + NC output. Do not exceed 5A in each group. Life: 100,000 actions Terminal V+: Power supply + NO1: Relay NO contact 1 NC1: Relay NC contact 1 COM1: Relay contact common terminal 1 NO2: Relay NO contact 2 NC2: Relay NC contact 2 COM2: Relay contact common terminal 2 Time Range Setting: When the selector switch is set to 30 position, it means that 0-30 is adjustable When the selector switch is set to the 300 position, it means that 0-300 is adjustable Time Value Adjustment: Turn the adjustable resistor counterclockwise to decrease the time and clockwise to increase the time Time Unit Setting : When the selector switch is set to the Sec position, the unit is: second When the selector switch is set to the Min position, the unit is: minute Example: Requires a delay of 50 minutes: 1. Set time range at 300 position 2. Set time unit at Min position 3. Adjust the adjustable resistor to the 50 position. Application: Use with limit switch and induction switch to achieve: 1. Automatically close the door after timeout 2. Assembly line product interruption monitoring 3. Water/air flow interruption monitoring Package List 1 x Delay Relay Module
