The KEYENCE DL-PD1 is a compact PROFIBUS DP communication module from the DL series that aggregates D-bus sensor amplifiers into a single, PLC-ready node. Designed for factory automation, it streamlines multi-sensor integration on PROFIBUS networks for machine builders, OEMs, and maintenance teams seeking reliable, high-throughput fieldbus connectivity.

As a DP-V1 slave with a D-sub 9-pin interface (1 port), the DL-PD1 supports communication speeds from 9.6 kbit/s up to 12 Mbit/s, enabling flexible deployment across diverse PROFIBUS topologies. It connects up to 15 D-bus sensor amplifier units, operates on 20 to 30 VDC (with ripple tolerance), and consumes 1600 mW or less (65 mA max at 24 V). Engineered for industrial environments, it delivers stable performance from -20 to +55 °C with 35 to 85% RH, and withstands vibration and shock per the rated specifications. A durable polycarbonate housing and robust connector construction further enhance long-term reliability.

Whether upgrading legacy lines or commissioning new machines, the DL-PD1 reduces wiring effort, simplifies diagnostics, and accelerates commissioning while maintaining consistent data integrity across the PROFIBUS DP network; it’s a smart, scalable choice for sensor-level integration and comes backed by a 1-year warranty for added peace of mind.
