features and benefits
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 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 tET/tPET series provides a 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.
The tPET series offers true IEEE 802.3af-compliant (classification, 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 the DC adapter.
