  • 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

  • RS485TTL: Dieses Modul realisiert die gegenseitige Umwandlung zwischen TTL-Signal und RS485-Signal, keine Notwendigkeit, "Empfangen - Senden" zu steuern, verwenden Sie dieses Modul, während Sie den seriellen Anschluss so einfach bedienen, kompatibel mit 3,3 V und 5,0 V Netzteil, kompatibel mit 3,3 V und 5,0 V Signal.
  • Verfügt über RXD, TXD-Signalanzeige, Monitor-Send- und Empfangsstatus. Lieferumfang: 5 Stück TTL Turn RS485 Modul.
  • Anti-Interferenz-Fähigkeit, während es effektiver 485 Minen Design, im industriellen Bereich und Feld rauer Umgebung, Übertragungsreichweite von bis zu 1000 Metern des 850 Meters des 2 x 1,5 Kabels testen, wird empfohlen, innerhalb von 800 Metern zu verwenden, mehr als 800 Meter, bitte fügen Sie Repeater hinzu).
  • 【Einfache Bedienung】 Berücksichtigen Sie das 485-Bus-Lightning-Schutz-Design und das Anti-Jamming-Design, die Fernübertragung im Feld, der "Erd" -Seitenzugang des Moduls zur Erde, kann einen sehr guten Anti-Jamming- und Blitz-Effekt spielen, 485-Bus sicherer; Indoor-Kurzstreckenübertragung kann nicht auf die Erde zugreifen.
  • Die Verwendung von Standard 2,54 Pitch Design, um Ihre sekundäre Entwicklung zu erleichtern. Mit 120 Ohm Matching-Widerstand, kurzgeschlossen R0, um passenden Widerstand zu ermöglichen, Fernübertragung des vorgeschlagenen Kurzschlusses.
