Providing various digital I/O functions, the tET/tPET series 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 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 tPET-P2A2 perfect integration with the HMI, SCADA, PLC, and other software systems.

The functionality of the tET/tPET series is almost the same as the ET-7000/PET-7000 series. The tET/tPET series tiny Ethernet I/O modules support various I/O types, like photo-isolated digital input, relay contact, photoMOS relay, and open-collector output. The module can be used to create DI to DO pair-connect through the Ethernet. Once the configuration is completed, the tET/tPET series module can poll the status of local DI channels and then use the Modbus/TCP protocol to continuously write to a remote DO device in the background.

The ICP DAS tPET-AD2  is an analog input module that includes 2 single-ended analog input channels and provides a programmable input range on all analog inputs (0 ~ 500 mV, 0 ~ 1 V, 0 ~ 2.5 V, 0 ~ 5 V, 0 ~ 10 V, 0 ~ 20 mA, 4 ~ 20 mA).

It provides high overvoltage protection of 120 VDC. The sampling rate of the tPET-AD2 is adjustable and is available in either fast or normal mode. It also provides 4 kV ESD protection as well as 3000 VDC intra-module isolation.
