The WAGO 750 series Fieldbus coupler, also known as a remote I/O (RIO) controller unit, features PROFIBUS communication capability and supports up to 64 connections per node and 96 fieldbus nodes on the master connection. It operates on a 24Vdc supply voltage via system wiring and power jumper, and includes a 9-pin D-sub female connector for fieldbus, spring CAGE CLAMP for power supply connections, and a 4-pin male connector for device configuration. Designed for DIN-35 rail mounting with a width of 50.5mm, it is rated for IP20 protection and suitable for ambient temperatures ranging from 0°C to +55°C, equivalent to model 750303.
