  • 【Ampia Applicazione】La tensione di lavoro del modulo relè RS485 a 16 canali è 12V DC. Il "carico" può essere telecamere, luci a LED, ventilatori, motori e altri dispositivi DC 12V. Sono otticamente isolati, garantendo sicurezza, affidabilità e anti-interferenza per il controllo MCU, il settore industriale e il controllo PLC.
  • 【Facile da Usare】La corrente di riserva (tutti i relè chiusi) è 11MA, 1 relè apre 40MA, 2 relè apre 67MA, 3 relè apre 95MA, 4 relè apre 121MA, 5 relè apre 147MA, 6 relè apre 173MA, 7 relè apre 198MA e 8 relè apre 222MA.
  • 【Funzioni di Esecuzione Multiple】Modulo relè ci sono 6 comandi: "aprire", "chiudere", "istantaneo", "autobloccante", "interblocco" e "ritardo" per soddisfare i diversi requisiti di controllo del circuito.
  • 【Metodi di Controllo Multiple】Modulo relè con controllo seriale super terminale (richiede l'aggiunta manuale di CRC), controllo software di polling MODBUS (software aggiunge automaticamente CRC), controllo di processo PLC o MCU.
  • 【Modalità di Controllo del Comando Modbus】Il ritardo massimo è di 255 secondi. In modalità di comando MODBUS, il modulo relè può supportare fino a 64 dispositivi paralleli. I comandi MODBUS possono essere inseriti nel super terminale seriale (assistente seriale) o nel "polling MODBUS".
