Χαρακτηριστικά

This product is an 8-ch relay module designed for industrial environments, featuring dual Ethernet interfaces control and 8 digital inputs. It adopts Modbus RTU / Modbus TCP protocols, supports Ethernet port cascade and PoE power supply, also comes with an ABS rail-mount case. The Modbus POE ETH Relay (C) 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 requirements.

Features

Dual Ethernet ports design, supports Ethernet port communication cascade and PoE power supply cascade
Features flash-on, flash-off function, by passing arguments to the command, it is possible to turn on the relay for a while and then close it automatically
Supports DC 7V–36V wide range power input and PoE power supply
Supports relay control through MQTT protocol, comes with Alibaba Cloud MQTT application demo
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
4 LEDs and Network indicators for indicating the MCU status and signal transceiving status
