The t(P)ET-P2R2/tET-P2R2 is an IP-based tiny ethernet I/O monitoring and control module that can be remotely controlled through a 10/100M ethernet network by using Modbus TCP/UDP protocol. This makes the device suitable for integrating into the HMI, SCADA, PLC and other software systems.

The module contains two channels of photoisolated digital inputs and two channels of form-A power relay outputs and can be used to create a DI to DO pair-connection through the ethernet. Once the configuration is completed, it polls the status of the local DI channels and then writes to a remote DO device continuously in the background using the Modbus/TCP protocol.

The device features a 32-bit MCU to enable efficient handling of network traffic. It also has a built-in web server that provides an intuitive web management interface to allow users to modify the settings of the module including DHCP/static IP, gateway/mask.

It is designed for ultra-low power consumption offering IEEE 802.3af-compliant power over ethernet using a standard category 5 ethernet. The modules can also accept power input from a terminal block if no PoE is present.

The built-in dual watchdog timer (CPU watchdog and host watchdog) ensures continuous operation even in harsh environments and automatically resets the CPU if the built-in firmware is operating abnormally.
