Interfaces & Indicators
With Multiple LED Indicators, Easy To Monitor The Operating Status
| RUN | Ethernet port indicator, blinking when Ethernet port is normally working |
| STA | MCU indicator, blinking when the MCU is normally working |
| TXD | TX indicator, lights up when sending data |
| RXD | RX indicator, lights up when receiving data |
| Left Ethernet Port Green Indicator | Lights up when the connection of Ethernet Port 1 is established |
| Right Ethernet Port Green Indicator | Lights up when the connection of Ethernet Port 2 is established |
| Left Ethernet Port Yellow Indicator | Lights up when the TCP connection is established |
| Right Ethernet Port Yellow Indicator | Data activity indicator, blinking when transmitting data |
Multiple Modes for Various Automation Scenarios
Supports multiple relay control modes, each channel supports independent
control mode setting
Note: Except for linkage mode, all other modes also support relay control via commands.
Support Ethernet Port Cascade and PoE Cascade Power Supply
Onboard 2-ch Ethernet Ports for communication and cascade
Either one can be used for dual serial server network communication, while the other one can be used for cascading or communication with other devices
* Note: Each module in the cascade needs to be powered individually or using PoE cascade power supply. The maximum power consumption of a single module is 7W, please pay attention to the output power of Router when using PoE cascade power supply.
Relay Connection
Contact rating of the onboard relay up to 10A 250VAC/30VDC
