30A DC 12V Delay Timing Relay Module Delay Timer Board 0.1-5 Seconds Time Range Condition: Item Type: Time Delay Relay Module Voltage: DC 12V (10V-15V can be used) Power Consumption: Standby 0.04W Work: 1.0W Startup Mode: start timing on power-on Time Range: 0.1-5 seconds Delay Accuracy: 1% Load: AC 250V 30A or DC 30V 30A Output form: A group of normally open + normally closed Can be set to one of two modes of operation: A: Power on immediately, after the delay arrives, disconnected (maintained disconnected until the input is powered off); B: It will not operate after power-on, and will be turned on after the delay arrives (always on until the input is powered off). A Mode: After the module is connected to the power supply, the red indicator light indicates that the power is on. The relay works immediately and the green indicator light is on. At this time, the normally open and common terminals are switched to the on state (the normally closed terminal is disconnected). - After a period of time, the relay is turned off and the green indicator is off. At this time, the normally open and the common terminal are switched off (the normally closed terminal is turned on). Keep this state until the input is powered off. B Mode: When the module is connected to the power supply, the red indicator light indicates that the power is on. The relay does not move, the green indicator light does not illuminate, and the normally open and the common terminal remain in the off state before the power is turned on (the normally closed terminal is turned on). After a period of time, the relay is turned on and the green indicator light is on. At this time, the normally open and the common terminal are switched to the on state (the normally closed terminal is disconnected). Keep this state until the input is powered off.
