Χαρακτηριστικά

This product is an industrial 8-channel relay module controlled via an Ethernet port, featuring 8-channel digital input. It supports Modbus RTU and Modbus TCP protocols, offers PoE power supply, and comes in an ABS rail-mount case. Designed for ease of use, it ensures fast communication, stability, reliability, and safety, making it an ideal choice for industrial control equipment or applications requiring high-speed communication.

Technical data

Power supply	PoE Ethernet Port, DC 5.5×2.1 Power Port or Power Supply Screw Terminal (7~36V)
Communication interface	PoE Ethernet Port, Support IEEE 802.3af Standard
Relay channels	8 Channels
Touch contact	1NO, 1NC
Touch contact load	≤10A 250V AC or ≤10A 30V DC
Digital input	8DI, 5~36V, Passive Input/Active Input (NPN or PNP) Built-in Bidirectional Optocoupler
Modbus protocol	Modbus RTU Protocol or Modbus TCP Protocol

Features

Supports reading digital inputs via Modbus RTU protocol commands and controlling relay output based on input signals.
Compatible with TCP Server, TCP Client, UDP Mode, UDP Multicast, HTTP, MQTT, Modbus RTU, and Modbus TCP protocols.
Allows software and web browser configuration, supports dynamic IP assignment via DHCP, and connects to domain name servers via the DNS protocol.
Includes a flash-on/flash-off function, enabling relays to turn on for a specified duration before automatically switching off.
Supports a wide input voltage range of DC 7–36V and PoE power supply.
Enables relay control through the MQTT protocol and includes an Alibaba Cloud MQTT application demo.
Utilizes a dedicated relay driver chip with built-in flyback diode protection for enhanced stability and driving capability.
Supports both passive and active digital input with bidirectional optocoupler isolation and an integrated debouncing algorithm. The relay allows digital input linkage or toggle control.
Features a reverse-proof circuit to prevent damage from incorrect wiring.
Housed in a rail-mounted ABS plastic enclosure for easy installation and safe operation.
Equipped with four LEDs and network indicators to display MCU status and signal transmission.

Indicator description

Indicator	Description
RUN	The network port operation indicator, when the network port is working normally, will output a square wave with a period of 2 seconds
STA	MCU indicator, blinks when MCU is working normally
TXD	Transmitting indicator, light on when transmitting data
RXD	Receiving indicator, light on when receiving data
Network port green indicator	Green indicator is on when TCP connection is established, used to determine if the module has established a communication link with the host computer software
Network port yellow indicator	Data transmission light, when there is data transmission on the network port, the yellow light transition state will change, which can be used to determine whether there is data transmission
