Features

tET-PD2R1 Application ImageProviding networking ability and various digital I/O functions, the tET-PD2R1 models are IP-based Ethernet I/O monitoring and control modules. The module can be remotely controlled through a 10/100 M Ethernet network by using Modbus TCP/UDP 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-PD2R1 perfect for integration with the HMI, SCADA, PLC and other software systems.

The functionality of the tET-PD2R1 is almost the same as the PET-7000 series. The tET-PD2R1 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 modules 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. It's useful when connecting digital I/O devices that do not themselves have Ethernet capability.

The tET-PD2R1 provides dual watchdog: CPU watchdog and host watchdog. The CPU watchdog automatically resets it-self 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 predefined state (safe value) when the host fails.

For maximum space savings, the tET-PD2R1 is offered 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 efficient network trafficking. The tET-PD2R1 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 tET series accepts power input from DC adapter.
