#1 GAGNANT

  • This product is an industrial 16-ch relay module controlled via RS485 bus, adopts Modbus RTU protocol, built-in protection circuits such as power supply isolation, ADI magnetical isolation, resettable fuse, and TVS diode, etc. It also comes with an ABS case.
  • The Modbus RTU 16-Ch Relay is an extremely user-friendly device. With its fast communication, stability, reliability, and safety features, it stands out as an excellent option for industrial control equipment and applications that demand high communication capabilities.Rail-mounted ABS case, easy to install, safe to use.
  • Configurable device address (1~255), multi devices can be cascaded on RS485 bus.High quality relay, contact rating: ≤10A 250VAC/30VDC.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 ADI 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.Onboard dedicated relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable.Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection.3 LEDs for indicating the MCU status and signal transceiving status.

  • Adresse d'appareil configurable (1 ~ 255), plusieurs appareils peuvent être montés sur le bus RS485. Caractéristiques : fonction flash-on, flash-off, en passant l'argument au commun, il est possible de tourner le relais pendant un moment et ensuite de le fermer automatiquement
  • Isolation de l'alimentation unibody intégrée, offre une tension isolée stable, ne nécessite pas d'alimentation supplémentaire pour le terminal isolé. Isolation magnétique intégrée unibody, permet une isolation du signal, une haute fiabilité, une forte anti-interférence, une faible consommation d'énergie
  • Fusibles et TVS intégrés (transformateur de tension transitoire), supprime efficacement la tension de surge et la tension de pointe transitoire dans le circuit, offre une protection contre les surintensités et les surtensions, résistant à la lumière et anti-électrostatique
  • Isolation optocoupleur intégrée, empêche le relais d'être interféré par le circuit à haute tension. Adopte la puce de pilote de relais dédiée, avec protection de diode anti-vol intégrée, pour une conduite plus solide et plus stable
  • Circuit anti-inverse, empêche le circuit d'être endommagé accidentellement par une connexion incorrecte. Relais de haute qualité, indice de contact : ≤ 10 A 250 VAC/30 VDC. Fermeture en plastique ABS monté sur rail, facile à installer, sûr à utiliser. 3 LED pour indiquer le statut du MCU et le statut de transmission du signal
