Function 1: Timing Pull-in: after power on, when arrived the setting time T 1, the relay pull-in, and the T 1 can be adjustable between 0.1 second - 270 hours, give IN1 interface a low pulse signal, repeat the above function. Function 2: Timing Disconnect: after power on the relay pull-in, when arrived the setting time T 1, the relay disconnect, and the T 1 can be adjustable between 0.1 second - 270 hours, give IN1 interface a low pulse signal, repeat the above function. Function 3: Timing Pull-in Then Disconnect: after power on, the relay do not pull-in, when arrived the setting time T 1 relay pull-in; when arrived the setting time T 2 relay disconnect, and the T 1 and T 2 can be adjustable between 0.1 second - 270 hours, give IN1 interface a low pulse signal, repeat the above function. Function 4: Timing Disconnect Then Pull-in: after power on, the relay immediately pull-in, when arrived the setting time T 1 relay disconnect; when arrived the setting time T 2 relay pull-in, and the T1 and T 2 can be adjustable between 0.1 second - 270 hours, give IN1 interface a low pulse signal, repeat the above function. Package Included: 1 x Time Delay Relay
