Description
Waveshare 16-Channel Ethernet Relay Module
Industrial-grade relay module featuring Modbus RTU/Modbus TCP, dual Ethernet ports for communication/cascade, and PoE (802.3af) or 7–36 V DC power. Perfect for PLC/SCADA, building and plant control.
Key Features
- 16 relays, contact rating ≤ 10 A @ 250 VAC / 30 VDC
- Modbus RTU & Modbus TCP; plus TCP server/client, UDP (unicast/multicast), HTTP, MQTT (demo)
- Dual-LAN for cascade/forwarding; PoE cascade supported*
- PoE (802.3af) or DC 7–36 V (PSU optional, 12 V recommended)
- Industrial protections: optocoupler isolation, driver IC with flyback diode, reverse-polarity protection
- Status LEDs: RUN, STA, TXD, RXD; per-port link/activity
- DIN-rail ABS enclosure for fast cabinet installation
*Each module needs its own power or PoE cascade; mind total PoE budget. Max. power ≈ 7 W.
