[Introduction]：E830-DTU (2R2-433L) est un produit de télécommande avec des fonctions de suivi de commutateur et d'acquisition de contrôle. Il prend en charge 2 entrées de commutateur isolées et 2 sorties de relais.La coque adopte un revêtement à trois niveaux : antifongique, anti-humidité et anti-sel. La coque adopte un revêtement à trois niveaux : antifongique, anti-humidité et anti-sel.L'interface de communication adopte l'interface RS-485 (utilisée uniquement en mode de configuration) ; le sans fil La fonction d'acquisition prend en charge le protocole standard MODBUS RTU. Ce produit est très facile à utiliser et peut être largement utilisé dans l'acquisition de signaux, la surveillance et le contrôle des équipements de terrain industriels.
| Pin number | Name | Function | Description |
| 1 | DI1 | Switch input channel 1 | 1 channel of switching value acquisition, optocoupler isolation |
| 2 | COM1 | Switch input channel 1 | The common terminal of input channel 1 is internally connected to the module ground. |
| 3 | DI2 | Switch input channel 2 | 2 channels of switching value acquisition, optocoupler isolation |
| 4 | COM2 | Switch input channel 2 | The common end of input channel 2 is internally connected to the module ground. |
| 5 | RESET | reset button | In acquisition mode, you can press and hold the soft button for 5 seconds to reset the Modbus address to the default address 01. |
| 6 | 485_A | RS-485 interface A | RS-485 interface A is connected to the device A interface and is only used to configure parameters. |
| 7 | 485_B | RS-485 interface B | RS-485 interface B is connected to the device B interface and is only used to configure parameters. |
| 8 | GND | Pressed wire power input negative pole | Power reference ground |
| 9 | VCC | Pressed line power input positive pole | Power input terminal, range: DC8-28V, recommended 12V, 24V |
| 10 | PWR/ACK | Power/ACK indicator light | Two-color light, blue light is the power indicator light, always on when power is on, green light is the ACK indicator light |
