SELECTED OPTION:
CHANNEL: 2CH
1-Channel: 1. RS485 communication interface 2. TTL communication interface 3. 1 way input 4. 1 way output 5. A user LED indicator 6. A STM32F030F4 microcontroller 7. A LEDs indicating the status of the relay 8.? Power terminal interface (12V power supply)
2-Channels:
Input and output wiring and function description: Output part: NC (normally closed) COM (common pin) NO (normally open) Load 220V 10A is recommended below 220V 6A 1. It is just the closing and opening of a switch without any voltage output. 2. The relay can only be turned on and off by sending commands through 485 communication. 3. By default, NC COM is connected. When 485 sends the opening command, NC and COM are disconnected, NO and C0 are connected, and vice versa. Input part: IN1 connects to switch or voltage signal (3V-30V) 1. The status of the switch can only be read through the computer, and the relay cannot be controlled 2. IN1 is connected to the switch (no voltage signal): IN1 connected to VCC is 1, and not connected to 0
1. RS485 communication interface 2. TTL communication interface 3. 2 optocoupler isolated inputs 4. 2 optocoupler isolated output 5. A user button 6. A user LED indicator 7. A power indicator 8.
