Wireless I/O, also known as radio telemetry, connect directly to sensor and control signals, and transmit the signal values by radio. The signals are either re-created as similar signals, or output as a data connection — Ethernet, Profibus, Modbus etc. Wireless I/O networks can be as simple as two units transferring a small number of signals from one point to another, or they can be complex data-acquisition networks with multiple “master” interfaces to external systems.
Download: Universal Wi‑Fi and I/O Modem — This Weidmuller flyer covers the WI‑I/O‑2‑E‑N‑GBL industrial Wi‑Fi modem and I/O gateway for connecting sensors and actuators in remote or hard‑to‑reach locations. It supports 802.11 b/g/n wireless networking, Modbus RTU/TCP communication, and built‑in digital and analog I/O with a web dashboard for real‑time monitoring and control across industrial environments.
