The ICP DAS tET/tPET series is an IP-based Ethernet I/O monitoring and control module. The ICP DAS tET/tPET module can be remotely controlled through a 10/100 M Ethernet network by using Modbus TCP protocol which makes the ICP DAS tET/tPET series perfect integration with the HMI, SCADA, PLC and other software systems.

The ICP DAS tET/tPET tiny Ethernet I/O modules support various I/O types such as photo-isolated digital input, relay contact, photoMOS relay, and open-collector output. This module can be used to create DI to DO pair-connect through the Ethernet. Once the configuration is completed, the ICP DAS tET/tPET series module can poll the status of the local DI channels and then use the Modbus/TCP protocol to continuously write to a remote DO device in the background.
