Introduction:
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 de facto 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.
