Product Description Industrial 8/30-Channel Ethernet Relay Module Modbus RTU/TCP Protocol Poe Ethernet Communication

8-Way Ethernet Relay Module:
Description:
This product is an 8-way relay module controlled by Ethernet interface specially designed for industrial environment applications. It adopts Modbus RTU/Modbus TCP protocol, supports PoE network port power supply, and ABS rail housing design. This product is easy to operate, with the characteristics of fast communication speed, stability, reliability and safety, and can be applied to various industrial control equipment or applications with high communication requirements.

Features:
It has flash-on and flash-off functions, and can control the relay to open for a period of time and automatically close through instructions
Support DC 7~36V wide voltage power supply, support PoE Ethernet power supply
Support control of relays through MQTT protocol, and provide Alibaba Cloud MQTT application routines
Onboard optical coupler isolation to avoid interference from relay high-voltage circuit
Onboard anti-reverse connection circuit to avoid reverse connection of positive and negative poles and burnout of circuit
Use high-quality relays, allowing access to loads: ≤10A 250V AC or ≤10A 30V DC
Rail-type ABS protective housing, easy to install and use, safer with housing
External 4 LED indicators and network port indicators, you can easily view the MCU status and signal receiving and sending supply: PoE network port, DC 5.5*2.1 power interface or terminal block (7~36V)
Communication interface: PoE network port, support IEEE 802.3af standard
Number of relays: 8
Contact type: one normally open, one normally closed
Contact load: ≤10A 250V AC or ≤10A 30V DC
Modbus protocol: Modbus RTU protocol or Modbus TCP protocol
Indicator:
