Features Power-off delay disconnection, there is signal - ON, no signal - delay OFF. Double output contacts. Each channel maximum current is 5A. Adjustable time range 0-30/0-300 and time unit second/minute. Rotate the adjustable resistor to setup delay time. Specification: Item Type: Delay Off Relay Module Voltage: 12V DC (10-16V) 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 Input: Voltage signal, valid signal above 1.5V, current needs at least 0.1mA Terminal V+: Power supply + GND: Power supply -, also the reference GND for the signal voltage IN: Signal voltage input, low level below 1V, high level above 1.5V, and uncertainty in the middle. Withstands up to 30V 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. Package List: 1 x Delay Relay Module Package List 1 x Delay Relay Module
