8 channel Digital input (Wet/Dry), 8 channel Digital output, Ethernet, 2 x LAN Daisy-Chain. Modbus TCP/IP, MQTT, -25 - +75°C

With digital DI and DO function, the 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 using Modbus TCP/UDP protocol. Modbus has become a de facto standard communication protocol in industry and is now the most widely available means of connecting industrial electronic devices. This makes the module perfect for integration with HMI, SCADA, PLC and other software systems.

Has 16 digital input channels for wet contact and dry contact. With 2 Ethernet ports, the module allows daisy chain connection, which allows flexibility in locating devices, eases installation and lowers infrastructure costs. It has 8 kV ESD protection, 4 kV EFT protection. Each input channel can be used as a 32-bit counter.

The module can be used together with a DO module to create a DI to DO pair connection through Ethernet. After configuration, the module can poll the status of the local DI channels and then use the Modbus/TCP protocol to continuously write to the external DO devices.

It is equipped with a removable terminal block connector for easy and robust wiring in industrial situations and has a powerful 32-bit ARM MCU to handle efficient network traffic.
