ET-2268 CR ICP DAS Relay Module

Providing a variety of digital I/O functions, the ET-2268 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 industrial application, and is now the most commonly available means of connecting industrial electronic devices. This makes the ET-2268 module being perfectly integrated with the HMI, SCADA, PLC or other software systems.
The ET-2268 provides 4 Form A signal Relay output and 4 Form C signal Relay Output channels. With 2 Ethernet ports, the ET-2268 allows daisy chain connection which enables flexibility in locating devices; easy installation and lower infrastructure costs. This module includes 8 LED indicators that can be used to monitor the Relay Output status, and options are provided that allow power-on and safe Digital Output values to be configured. It features 8 kV ESD, 4 kV EFT and 3 kV surge protection to enhance noise protection capabilities in industrial environments. The ET-2268 is the ideal solution for small signal switching.
The module can be used to create DI to DO pair-connect through the Ethernet. After configuration, the ET-2268 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.
