Features: 100% brand new and high quality Small body and stable performance. This module is programmable and can realize thousands of functions. Work performance is stable and reliable. Built-in timing circuit can effectively long-term operation of the module. Function:1. Turn on the power, the relay 1 is after N seconds of closing; then the relay 2 is after N seconds of closing.2. Turn on the power, the relay 1 is turned off after N seconds of closing; then the relay 2 is turned off after N seconds, and then cycles.3. When the power is turned on, the relays 1 and 2 are not activated. When there is a signal or a button is triggered, the relay 1 is turned off after N seconds is ; then the relay 2 is turned off after N seconds and then turned off until the trigger, repeating the same action.By programming the signals 1, 2, any control of the relays 1 and 2 can be achieved.4. When signal 1 has a signal, relay 1 is and relay 2 is turned off; 5. When signal 2 has a signal, relay 1 is turned off and relay 2 is .6. the NPN sensor signal can be connected, and the sensor signal can be programmed to realize any control of the relay.7. When signal 1 has a trigger, control relay 1; when signal 2 has a trigger, control relay 2.8. Turn on the power, control the motor to rotate for N seconds, then reverse N seconds, and cycle.9. When the signal 1 has a signal, the motor is controlled to rotate forward; when the signal 2 has a signal, the motor is reversed.
