UCD-DPC1B-1416-HBY0-H72 Profibus Address and Ø11 Hollow Shaft

UCD-DPC1B-1416-HBY0-H72 can be supported by EncoderWorks with a custom compatible replacement focused on Profibus DP node identity, 30-bit position mapping, and ø11 mm blind hollow-shaft fit. This model should not be treated as a simple multiturn encoder exchange. The encoder may power up correctly, while the controller still rejects the node or reads the wrong position because the address, terminal resistor, DP profile settings, preset value, or shaft seating was not reproduced.

The UCD-DPC1B-1416-HBY0-H72 is a POSITAL IXARC multiturn absolute encoder with Profibus DP interface, DPV0 / DPV1 / DPV2 Class 2 support, magnetic sensing, binary code, 16-bit singleturn resolution, 14-bit multiturn resolution, self-powered magnetic pulse counter multiturn technology, steel housing, ø58 mm blind hollow flange, radial three-M12 connection cap, and ø11 mm blind hollow shaft.

The first failure boundary is Profibus node setup. This encoder uses visible address selector switches from 0 to 99 and a terminal-resistor switch in the connection cap. If the node address, Bus In / Bus Out direction, or termination state is wrong, the master can lose Data Exchange even though the encoder and supply voltage are healthy.

This replacement fails when the Profibus device is powered, but the PLC receives no valid position because the node number, terminal resistor, Bus In / Bus Out wiring, or DP profile configuration does not match the original encoder. That is a bus-setup failure, not a magnetic sensing failure.

The second boundary is parameter agreement. Resolution, gearing factor, velocity scaling and filter, preset, counting direction, limit switches, teach-in, diagnosis, and node number can all affect the value seen by the controller. A replacement may communicate normally and still report the wrong absolute position if the Class 2 configuration is not copied.

Mechanically, the ø11 mm blind hollow shaft has defined static and dynamic misalignment limits. The clamping ring, shaft seating depth, radial connector clearance, and shield grounding must be checked before startup. IP65 shaft protection and IP66/IP67 housing protection do not correct poor hollow-shaft fit or cable strain at the M12 cap.

The replacement decision should first confirm Profibus DP profile compatibility, node address, terminal-resistor state, Bus In / Bus Out M12 mapping, 10–30 VDC supply, 16-bit singleturn and 14-bit multiturn mapping, preset value, counting direction, velocity settings, diagnosis behavior, ø11 mm hollow-shaft fit, clamping-ring condition, misalignment limits, and shield grounding. EncoderWorks treats UCD-DPC1B-1416-HBY0-H72 as an industrial encoder custom compatible solution where Profibus node identity and hollow-shaft mechanics decide field reliability.

Typical production lead time: 15 working days.
