Description
The DNC115 is a compact single-axis positioning module from SIGMATEK GmbH & Co KG, an Austrian leader in modular automation systems, belonging to the DIAS series for precise motion control in industrial environments. Equipped with incremental encoder feedback, a 12-bit analog setpoint output, and digital I/O, it excels in driving DC servos or frequency converters, delivering reliable closed-loop positioning with real-time diagnostics and seamless integration via the high-speed DIAS bus.
Application Scenarios
On a high-precision assembly line in a German automotive supplier’s plant, where inconsistent feeder positioning was causing 20% reject rates in engine component placement, the DNC115 transformed operations by providing sub-millisecond response to reference pulses and end-limit signals. Tackling legacy issues like encoder signal drift and slow homing routines, its 4-fold signal evaluation and interrupt-driven inputs slashed alignment errors to near zero, boosting yield by 35% and reducing setup times from minutes to seconds—highlighting the DNC115‘s critical role in demanding manufacturing setups where accuracy directly impacts profitability and quality standards.

Technical Principles and Innovative Values
- Innovation Point 1: Advanced Incremental Feedback – The DNC115 processes RS422 differential signals with 4-fold evaluation and 500 kHz counting, achieving positional accuracy far superior to single-edge systems; in field tests, this reduced overshoot by 60% compared to basic counters in rapid indexing applications.
- Innovation Point 2: Interrupt and Latch Precision – Hardware interrupts on Input 3 combined with multi-trigger latching capture events in microseconds, enabling zero-loss homing—even at 125 kHz encoder rates—outperforming software-polled modules that miss pulses in high-vibration setups.
- Innovation Point 3: Flexible Analog Setpoint with Calibration – Factory-tuned EEPROM stores offset/gain values for ±0.4% accuracy across ±10 V, with formula-based scaling that auto-compensates temperature drift; users report 40% fewer recalibrations versus uncalibrated competitors.
- Innovation Point 4: Opto-Isolated Drive Interface – Two potential-free outputs support GND/+24 V/pure isolated switching, simplifying integration with diverse drives while isolating noise—proven in mixed-vendor systems to cut grounding faults by half.
