8-Channel Relay PoE Ethernet RTU/Modbus TCP Protocol

The PoE ETH 8-CH relay module is an industrially deployable 8-channel relay that is controlled via Ethernet and uses the Modbus RTU protocol. It offers numerous protection circuits, easy handling, and reliable performance for industrial control applications. With a contact rating of ≤10A 250VAC/30VDC, it is ideal for controlling household appliances and devices under 30VDC. The rail-mounted ABS housing allows for easy and safe installation.
