The RF I/O and RF 96 wireless modules are especially suitable for use on rotating, temporarily installed or accessible machine parts. The wireless universal transmitter can be directly mounted on machines and plants. The wiring of the »last metre« to the sensors is carried out radially in the conventional manner, for example by prewired M12 plug-in connectors. Up to 4 RF sensors can be connected to one RF I/O. Alternatively mechanical position or cam switches can also be connected. Wireless transmission is performed by the tried-and-tested sWave® wireless technology (SW868/SW915/SW922).
