Features: brand new and high quality Small body and stable performance. This module is programmable and can realize thousands of functions. Working performance is stable and reliable. Built-in timing circuit can effectively long-term operation of the module. Function:1. Turn on the power, relay 1 is closed after N seconds; then relay 2 is closed after N seconds. 2. Turn on the power, relay 1 is turned off after N seconds of closing; then relay 2 is turned off after N seconds and then cycles. 3. When the power is turned on, relays 1 and 2 are not activated. When there is a signal or a button is triggered, relay 1 is closed after N seconds; then relay 2 is closed after N seconds and then turned off until the trigger, repeating the same action. By programming signals 1, 2, any control of relays 1 and 2 can be achieved. 4. When signal 1 has a signal, relays 1 and 2 are turned off; 5. When signal 2 has a signal, relay 1 is turned off and relay 2 is 0. 6. 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 for N seconds and cycle. 9. When signal 1 has a signal, the motor is controlled to rotate forward; when signal 2 has a signal, the motor is reversed.
