Introduction

Providing various digital I/O functions, the ET-2251 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 industry, and is now the most commonly available means of connecting industrial electronic devices. This makes the ET-2251 module perfect integration with the HMI, SCADA, PLC and other software systems.

The ET-2251 provides 16 wet contact & dry contact Digital Input channels. With 2 Ethernet ports, the ET-2251 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 are also provided to enhance noise protection capabilities in industrial environments. Each input channel can be used as a 32-bit counter.

The module can be used to create DI to DO pair-connect through the Ethernet. After configuration, the ET-2251 module can poll the status of the local DI channels and then use the Modbus/TCP protocol to continuously write to the remote DO devices.

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.
