Turck FDN20-S0404G Distributed IO Station Module

The TURCK FDN20-S0404G Device-Net distributed I/O station is a compact bus stop that provides four digital inputs and four digital outputs for near-machine, decentralized control. Powered from 24 VDC (Device-Net powered, 18–26 VDC range), it uses PNP 24 VDC inputs and PNP transistor outputs up to 0.5 A per channel, supports Device-Net fieldbus speeds of 125/250/500 kbps, and offers screw-terminal fieldbus and I/O connections with rotary switch addressing (0–63); MPN FDN20-S0404G / F0220. The IP20-rated, industrial-grade polymer housing supports DIN-rail or panel mounting and operates from -40°C to +70°C, with LED diagnostics for network and channel status, enabling use in automotive assembly lines, packaging machinery, conveyor systems, material handling, and other machine-level automation requiring local I/O; common replacements include TURCK FDNQ-S0404G-MM Device-Net I/O Station.
