ET-2261-16 Modbus TCP/UDP & MQTT Remote I/O Module. Ethernet Data Acquisition Module with 16 Channels of Form A Power Relay Output.

The ET-2261-16 module is an 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 industry, and is now the most commonly available means of connecting industrial electronic devices. This makes the ET-2261-16 module perfect for integration with HMI, SCADA, PLC and other software systems. The ET-2261-16 supports 16 Form A electromechanical Relays Output channels. With 2 Ethernet ports, the ET-2261-16 allows daisy chain connection which permits the flexibility in locating devices, eases installation and lowers 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-connect through the Ethernet. After configuration, the ET-2261-16 module can poll the status of remote DI channels via the Modbus TCP protocol and write data to local DO channels. It is equipped with removable terminal block connector for easy and robust wiring in industrial situations, and features a powerful 32-bit ARM MCU to handle efficient network trafficking.
