16-Channel Ethernet Relay Module – Modbus, PoE Support, Isolation Protection
The Waveshare Modbus POE ETH Relay 16CH is an industrial-grade 16-channel relay module controlled over Ethernet using Modbus RTU or Modbus TCP protocol. It features dual Ethernet ports for cascading, Power over Ethernet (PoE) support to IEEE 802.3af, and optocoupler-isolated relay drivers with flyback diode protection.
Each of the 16 relay channels provides both normally open (NO) and normally closed (NC) contacts rated at up to 10A @ 250VAC or 30VDC. The module supports configuration via software, web browser, or DHCP, and is also compatible with HTTP and MQTT protocols (including Alibaba Cloud MQTT). Housed in a DIN rail-mountable ABS enclosure for industrial installations.
Key Features
- 16 Relay Channels – Each with 1NO + 1NC contacts, rated ≤10A @ 250VAC / 30VDC
- Dual Ethernet Ports – Communication cascading for multi-device setups
- PoE Support – IEEE 802.3af Power over Ethernet, reducing cabling requirements
- Modbus RTU/TCP – Industry-standard protocol support via TCP and UDP
- HTTP & MQTT – Additional protocol support for IoT and cloud integration
- Optocoupler Isolation – Protects control circuitry from high-voltage relay switching
- Flyback Diode Protection – Dedicated relay driver chip with built-in protection
- LED Indicators – Power, Ethernet activity (RUN/STA), and data transmission (TXD/RXD)
- DIN Rail Mountable – ABS plastic enclosure with snap-on DIN rail installation
Specifications

- Contact Rating – ≤10A @ 250VAC or ≤10A @ 30VDC
- Power Input – DC 7–36V (terminal block or 5.5 × 2.1 mm barrel jack) or PoE (IEEE 802.3af)
- Power Consumption – ~0.6W (no load), ~6.5W (all relays energised)
- Communication – Dual Ethernet ports (Modbus RTU/TCP, HTTP, MQTT)
- Configuration – Software, web browser, or DHCP/DNS
- Operating Temperature – -15°C to 70°C
- Enclosure – ABS plastic, DIN rail mount
- Weight – 473g
Ideal For
- Industrial automation and remote relay control
- Smart home and building management systems
