Features Multifunctional: Relay module with emergency stop function ("STOP" button) and reverse input protection. Different OP, CL, LOP parameters can be set, the parameters are independent of each other and saved separately; 5 minutes without operation, it will automatically enter sleep mode and turn off the display, press any key to wake up. For Control: The trigger cycle delay module is 5V-36V wide voltage input, generally used to control DC motors, lights, LED light bars, micro pumps, solenoid valves, etc., very convenient. No Electromagnetic Interference: Timer module can realize fast high-frequency switching circuit, the number of switches is unlimited, the switch machine has no noise, no spark, and no electromagnetic interference. Lower Internal Resistance: The electromagnetic relay module is a dual MOS parallel active output, with lower internal resistance, larger current and strong power. Applicable to Most Equipment: The working current of the relay module can reach 15A at room temperature, and the power can reach 400W, which is suitable for most equipment. In the event of a power failure, all parameter settings are automatically saved. Specifications: Voltage: DC 5V~36V. Trigger Signal Source: High voltage level trigger (3.0V~24V), signal ground and system ground are not on common ground to improve the system's anti-jamming capability (you can also connect them on common ground). Output Capacity: DC 5V~36V, at room temperature, continuous current is 15A, power 400W. With enhanced heat dissipation, the current can be up to 30A. Quiescent Current: 20mA Operating Current: 50mA Working Temperature: -40℃~85℃ Clocking (Time Delay) Range: 0.1seconds to 999minutes Size: 60*34*12mm / 2.36*1.33*0.47"   Instruction:  Operating Mode: P1: trigger signal, the relay is on "OP" time, and then disconnect; in the "OP" time, as follows: P1.1: signal is triggered again, invalid P1.2: signal is triggered again, the clocking is reset P1.3: Signal is trigger again reset, relay off, and stop the clocking; P-2: trigger signal, the relay off "CL" of time, the relay on "OP" time, and then disconnect relay after clocking; P3.1: trigger signal, the relay is turned on after the "OP" time, the relay off "CL" time, then the operation cycles; if trigger signal again during the cycle, the relay off, stop clocking; the number of cycles times ( "LOP ") can be set. P3.2: without triggering signal after power on, the relay is on "OP" time, the relay off "CL" time, then the operation cycles; the number of cycles times ( "LOP ") can be set. P-4: signal holding function. If there is trigger signal, clocking is reset, the relay remains on; when the signal disappears, after clocking "OP" time, the relay is off; if another signal is triggered during clocking, clocking will be reset.
