• Industrial Modbus RTU 8-Ch Relay Module With RS485 Interface

Overview

This is an industrial 8-ch relay module  -8 input - 4 ADC - controlled via RS485 bus, utilizing Modbus RTU protocol. It features embedded protection circuits such as power isolation  TVS diode, etc. It also comes with an DIN Rail Mount enclosure.

The Modbus RTU Relay is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirement.

Features

  • 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 ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
  • Onboard Optocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
  • Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
  • High quality relay, contact rating: ≤10A 250VAC/30VDC
  • Rail-mounted enclosure, easy to install, safe to use
  • 3 LEDs for indicating the MCU status and signal transceiving status
