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 tET/tPET series 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 confi guration is completed, the 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.
The tET/tPET series provides dual watchdog: CPU watchdog and host watchdog. The CPU watchdog automatically resets it-self when the built-in fi rmware runs
abnormally. The host watchdog monitors the host controller (PC or PLC), and the output of the module can go to predefi ned state (safe value) when the host
fails.
For maximum space savings, the tET/tPET series is off ered in an amazing tiny form-factor that makes it can be easily installed in 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
effi cient network traffi cking. The tPET series off ers true IEEE 802.3af-compliant (classifi cation, Class 1) Power over Ethernet (PoE) using a standard category
5 Ethernet cable to receive power from a PoE switch like the NS-205PSE. When there is no PoE switch on site, the tPET series accepts power input from DC
adapter.
