Turck FDNL-CSG88-T DeviceNet IO Module

The TURCK FDNL-CSG88-T DeviceNet Bus Stop / Compact I/O Module is a compact distributed I/O node designed for DeviceNet automation networks, providing local sensor and actuator I/O close to the machine or process. It offers 8 PNP digital inputs and 8 24 VDC digital outputs (0.5 A per channel) powered from a 24 VDC DeviceNet supply, and supports 125, 250, or 500 kbps fieldbus transmission rates via M12 signal connectors plus a DeviceNet trunk connection. Node addressing is set with a rotary switch (0–63). Diagnostics include short-circuit monitoring and module-level fault indication, with galvanic isolation between fieldbus and I/O to help protect against transients. The enclosure carries IP67 protection and uses glass-fiber reinforced PA6-GF30 housing material, suitable for dirty, wet, or dusty industrial environments. Mounting options include four-hole panel or machine mounting, and the operating temperature range spans -40°C to +70°C. Typical applications include automotive assembly lines, packaging equipment, material handling systems, and conveyor automation where decentralized I/O and real-time DeviceNet communication are required. Common replacements cited include TURCK FDNL-CSG88-W and TURCK FDNL-S0808I-MM, with similar DeviceNet I/O functionality.
