UCD-DPC1B-1216-HRY0-H3P Profibus Absolute Encoder, 16-bit

We developed a custom solution for model UCD-DPC1B-1216-HRY0-H3P. Selected when multi-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 6.35 mm shaft, without battery replacement in long-cycle positioning systems. Typical production lead time: 15 working days. The referenced configuration combines 16-bit single-turn resolution, 12-bit multi-turn resolution, binary code, and a self-powered magnetic counter without battery or gear train.

Key Specifications

• Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
• Resolution: 16-bit single-turn + 12-bit multi-turn
• Code: Binary
• Multi-turn: self-powered magnetic counter, no battery, no gear train
• Supply: 10–30 VDC
• Protection: IP65 shaft side, IP66/IP67 housing
• Structure: 58 mm blind hollow, 6.35 mm shaft, 28 mm depth
• Connection: radial, 3 cable glands
• Speed: up to 12000 rpm
• Sensing: magnetic

Decision Snapshot

• Best for: Profibus absolute positioning systems needing battery-free multi-turn retention
• Key fit: 16-bit
• Avoid if: the system only needs incremental feedback or is standardized on another motion-bus architecture, because this version is built around Profibus Class 2 communication with switch-based addressing and connection-box topology.

Bus Configuration & Communication

The interface supports transmission up to 12 Mbaud, cycle time from 1 ms, and programmable functions including resolution, scaling, speed filter, preset, counting direction, limit switch, node number, teach mode, and diagnostics. The page also lists manual address selection 0–99 and termination resistor DIP switching in the connection box.

Primary integration value: bus-based multi-turn absolute transmission without parallel bit mapping.
Primary risk: address duplication, termination-switch errors, or bus continuity faults.
Best practice is address → termination → bus continuity → power, because this hardware uses switch-based addressing and dedicated bus in/out wiring.

Mechanical & Installation Focus

This version uses a 58 mm blind hollow flange, 6.35 mm shaft, 28 mm insertion depth, and published static/dynamic misalignment limits of ±0.3/±0.5 mm and ±0.1/±0.2 mm. Maximum speed is 12000 rpm.

Primary mechanical constraint: blind-hollow alignment at high shaft speed.
At this shaft size, shaft tolerance, insertion depth, and concentricity matter more than nominal flange size. Poor alignment will usually appear first as vibration, bearing stress, and unstable field behavior rather than instant startup failure. This is an engineering judgment grounded in the published speed and misalignment data.

Wiring & Bus Topology

The electrical layout uses radial connection with 3 cable glands. The connection plan separates Bus line A / B for bus in and bus out, plus Power Supply and GND on both sides of the bus path.

Primary commissioning issue: bus topology setup, not sensing stability.
Most startup problems on this structure come from address, termination, or continuity errors rather than from the encoder core itself.

Integration & Compatibility

• Designed for Profibus absolute encoder systems
• Matches 58 mm blind hollow installations with 6.35 mm shaft
• Suitable for multi-turn feedback where battery-free retention is preferred
• Not suitable for incremental-only systems or non-Profibus architectures

Lead Time

Typical production lead time: 15 working days. Custom adaptation can be developed around shaft fit, connection-box layout, and bus commissioning requirements.
