ICP Australia is proud to introduce ICP DAS’ ET-2261-16 Ethernet I/O Module with 16-ch Power Relay Output.

Providing a variety of digital I/O functions, the ET-2261-16 module is an IP-Based Ethernet I/O Monitoring and Control Module. The module can be remotely controlled through a 10/100 M Ethernet Network by using Modbus TCP/UDP Protocol. Modbus has become a standard communications protocol in industrial applications and is now the most commonly available means of connecting industrial electronic devices. This makes the ET-2261-16 module being perfectly integrated with the HMI, SCADA, PLC or other software systems.

The ET-2261-16 provides 16 Form A Electromechanical Relays Output Channels. With 2 Ethernet ports, the ET-2261-16 allows Daisy Chain Connection which enables flexibility in locating devices; easy installation and lower infrastructure costs. It features 8 kV ESD protection, 4 kV EFT protection, 3 kV surge and 3000 VDC I/O isolation to enhance noise protection capabilities in industrial environments.

The module can be used to create DI to DO pair-connection through the Ethernet. After configuration, the ET-2261-16 module can continuously poll the status of the local DI channels and then write to the remote DO devices via the Modbus/TCP protocol. It is equipped with removable terminal block connector for easy and robust wiring in industrial applications and features a powerful 32-bit ARM MCU to handle efficient network trafficking.
