Digital IO module

Versatile I/O acquisition modules equipped with ModBus for digital communication

The NXT I/O module family is compatible with ModBus RTU (RS485) and ModBus TCP (Ethernet) protocols.
The various models are equipped with RS485 serial, Ethernet, and WiFi, making them compact and ideal for interfacing with any device and for acquiring signals from different types of probes.

The inputs, outputs, and communication ports are galvanically isolated to protect the entire circuit.
The inputs are configurable, so each module is versatile and can be used for different types of probes.

ModBus I/O modules are designed and developed for applications in industrial environments. NXTs come with a DIN rail mount and are easy to install.
