16-Channel Ethernet Relay Module
Ethernet communication, support network port cascading, Modbus protocol and PoE power supply
Product Features
This product is a 16-channel relay module with dual Ethernet interface control designed specifically for industrial environment applications. It adopts Modbus RTU / Modbus TCP protocol, supports PoE network port power supply, and has ABS shell design. This product is easy to operate and has the characteristics of fast, stable, reliable and safe communication. It can be applied to various industrial control equipment or applications with high communication requirements.
- Dual Ethernet port design, supporting communication and PoE power supply cascading
- With flash-on/flash-off function, the relay can be set to delay closing after opening or delay opening after closing
- Supports DC 7V~36V wide voltage power supply and PoE Ethernet power supply
- Supports controlling relays via MQTT protocol and provides Alibaba Cloud MQTT application examples
- Onboard optocoupler isolation to avoid interference from relay high voltage circuits
- Adopting special relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable
- Onboard anti-reverse connection circuit to prevent the positive and negative poles from being reversed and burning the circuit
- Use high-quality relays to allow access to loads: ≤10A 250V AC or ≤10A 30V DC
- Rail-type ABS protective housing, easy to install and use, safer with housing
- Four external LED indicators and a network port indicator light make it easy to check the MCU status and signal receiving and sending status
Basic Functions
Supports sending Modbus RTU/TCP protocol commands to control relays via Ethernet, thus controlling various devices
Support multiple communication modes
Using Modbus protocol
Supports TCP server, TCP client, UDP mode, UDP multicast, HTTP and MQTT, Modbus RTU protocol and Modbus TCP protocol
Multiple configuration methods
Support software configuration, Web browser configuration,
Support DHCP to dynamically obtain IP, DNS protocol to connect to domain name server address
Multiple power supply methods, wide voltage input
Power plug type: directly use the power plug for power supply;
Terminal power supply: DC 7V~36V wide voltage range input;
Ethernet PoE power supply: applicable to IEEE 802.3af PoE standard
This product does not have an external power supply by default. If necessary, you can choose: 12V power supply
Ports and indicators
With a variety of indicator lights, it is convenient to check the working status of the module
| RUN light | The network port operation indicator light flashes when the chip is working normally |
|---|---|
| STA Light | MCU indicator light, flashes when MCU is working normally |
| TXD lamp | Sending indicator light, flashes when sending data |
| RXD Light | Receiving indicator light, flashes when receiving data |
| Left network port green light | Network port 1 flashes after connecting to Ethernet |
| Right network port green light | Network port 2 flashes after connecting to Ethernet |
| Left network port yellow light | Lights up after the module TCP connection is established |
| Right network port yellow light | Data activity light, when the module has data transmission, the yellow light status will change |
Supports network port cascade communication and PoE cascade power supply
There are 2 onboard network ports, both of which can be used for network communication and cascading.
One port can be used for dual serial port server network communication, and the other port can be used for cascading or networking other devices.
Note: Each module in the cascade can be powered individually or with PoE cascade power supply.
The maximum power consumption of a single module is about 7W. When using PoE cascade power supply, pay attention to the output power.
Relay Wiring
The device has a relay with a contact rating of 10A 250V AC or 10A 30V DC
Guide rail housing design
Rail-type ABS protective housing, easy to install and use, safer with housing
