12V Dual Channel Timer Relay Multifunctional Delay Timer Relay Time Control Switch DR42A01

Relays12V Dual Channel Timer Relay Multifunctional Delay Timer Relay Time Control Switch DR42A01 DR42A01 multifunctional delay relay control module, designed for the customers with different needs, use micro-controller as the main control unit, preset 18 kinds of functions, and can customize and add other specific functions based on user needs. The module adopts relay module, high-power high-voltage transistor, red lights, double-sided PCB board to get stable performance, can be widely used in a variety of power control applications. Function Description: The user can select one of the following 18 kinds of function according to keys and display, can set and save the parameters of the 18 kinds of function, also can view the current function parameters. Gentle remind: Function 1-8 start automatically after power on; function 9-18 required a low level pulse to trigger and start (low level duration20ms); Function 9 is self-locking mode; Function 10 is a level control mode. Function 1: Timing Pull-in: After power on, when arrived the setting time T1, the relay pull in and the T1 can be adjustable between 0.1 second and 270 hours, give CH1 interface a low pulse (low level duration20ms), repeat the above function for one time. Function 2: Timing Disconnection: After power on the relay pull-in. When arrived the setting time T1,the relay disconnect, and the T1 can be adjustable between 0.1 second -270 hours. Send a low pulse ( to IN1 interface, repeat the above function for one time. Function 3: Timing Pull-in Then Disconnect: After power on, the relay don't pull-in. When arrived the setting time T1, relay pull-in; when arrived the setting time T2, relay disconnect. And the T1 can be adjustable between 0.1 second -270 hours. Send a low pulse to IN1 interface, repeat the above function for one time. Function 4: Timing Disconnect Then Pull-in : After power on, the relay immediately pull-in. When arrive
