  • MA01-AACX2240 supporta l'acquisizione di un ingresso sensore a 2 canali (DI) e di un ingresso analogico sensore a 2 canali (AI), che viene convertito in porta seriale (RS485) e i dati vengono trasmessi al software di configurazione o al PLC. Il modulo di rete I/O con porta seriale (chiamato anche "IO remoto") realizza la funzione di acquisizione e controllo a distanza emettendo comandi attraverso la porta seriale per controllare 4 uscite di commutazione a relè (DO).
  • Supporto per i protocolli modbus RTU; supporto per tutti i tipi di software di configurazione / PLC / touch screen; RS485 Acquisition Control IO; alimentazione da 8 a 28 V CC;
  • 2 ingressi di commutazione DI (nodo secco); 2 ingressi analogici AI (da 0 a 20mA/4 a 20mA); 4 uscite di commutazione DO (relè); l'ingresso di commutazione (DI) supporta il conteggio; l'ingresso di commutazione (DI) supporta l'attivazione in salita, in discesa e a livello;
  • L'uscita di commutazione (DO) supporta la modalità di livello, la modalità a impulsi e la modalità follow; protezione dell'isolamento della porta di acquisizione in ingresso;
  • Comunicazione Baud Rate1200 to115200 (default 9600), supporta le impostazioni personalizzate; Supporto per 1to247 sottostazioni, il commutatore a 5 bit può essere impostato con un codice di indirizzo 1to31, maggiore di 31 può essere impostato da software

  • Configurable device address (1~255), multi devices can be cascaded on RS485 bus. Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically
  • Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
  • Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic. Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
  • Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability. Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. The relay supports digital input linkage control or toggle control
  • Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection. High quality relay, contact rating: ≤10A 250VAC/30VDC. Rail-mounted ABS plastic enclosure, easy to install, safe to use. Multiple LEDs for indicating the MCU status and signal transceiving status
