ET-2254
Ethernet I/O Module with 16-ch Universal DIO. Wide Operating Temperature Range: -25 ~ +75 °C. The ET-2254 provides Digital Output channel can drive 100 mA load, while the ET-2254P provides Digital Output channel can drive 400 mA load
Features
Providing a variety of digital I/O functions, the ET-2254 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-2254 module being perfectly integrated with the HMI, SCADA, PLC or other software systems.
The ET-2254 provides 16-channel Universal DIO. Each I/O port can be configured as DI or DO port. The ET-2254 provides Digital Output channel can drive 100 mA load, while the ET-2254 provides Digital Output channel can drive 400 mA load. There are configurable power-on and safe values for Digital Output. With 2 Ethernet ports, the ET-2254 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 3750 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-2254 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.
