ICP Australia is proud to introduce ICP DAS’s tPET-P2C2, which is a tiny PoE ethernet module with 2-ch DI and 2-ch. 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.

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 modules also provide dual watchdog: CPU watchdog and host watchdog. The CPU watchdog automatically resets itself when the built-in firmware runs abnormally. The host watchdog monitors the host controller (PC or PLC), and the output of the module can go to a predefined state (safe value) when the host fails.

For maximum space savings, the tET/tPET series is offered in an amazing tiny form factor that makes it can be easily installed anywhere, even directly embedded into a machine. It is equipped with two removable terminal block connectors for easy wiring and features a powerful 32-bit ARM MCU to handle efficient network trafficking.
