Series D1 fieldbus valve island with CoilVision technology

Flexible, Compact, and Modular Valve Control

The Series D1 valve islands are designed to deliver maximum pneumatic and electrical performance in compact applications. With support for multipole (25 or 44 pins) and fieldbus communication (PROFIBUS-DP, PROFINET, CANopen, EtherNET/IP, EtherCAT, IO-Link), the D1 series offers robust scalability for industrial automation.

Engineered for high density and flexibility, these valve islands support up to 128 coils across 64 valve positions, offering unmatched expandability and integration in a small footprint.

Key Benefits

• Compact footprint: Just 10.5 mm valve size with modular subbases in lightweight technopolymer.
• Flexible I/O expansion: Mix and match digital and analog I/Os; configure systems with or without fieldbus covers.
• Wireless-ready: Operational data transmission via WLAN is supported.
• COILVISION® technology: Continuous diagnostics of solenoid performance—monitor power draw, coil efficiency, and thermal changes.
• Easy Maintenance: Configure or expand without disconnecting from the machine.
• Visual Alerts: LED diagnostics indicate faults or anomalies via color and blink patterns.

Smart Performance with COILVISION®

The Series D1 integrates COILVISION®, a predictive maintenance system that ensures each solenoid operates within optimal parameters. Any deviation in power consumption, heat, or response time triggers LED alerts and notifies the PLC—helping avoid unplanned downtime and reducing maintenance efforts.

With its compact design, diagnostic intelligence, and plug-and-play modularity, the Series D1 valve island is a future-ready solution for industrial automation systems requiring both high-performance pneumatics and flexible electrical control. Whether you choose multipole or fieldbus integration, D1 guarantees exceptional reliability, monitoring, and ease of customization.
