ABB YPH108B Speed Measuring Board
The ABB YPH108B is a precision speed measuring board engineered for the ABB ACV 700 drive hardware family. It processes rotational speed feedback from incremental encoders to support closed-loop regulation and equipment protection in industrial drive systems.
This module accepts up to two incremental encoder inputs supporting single-ended or differential signals at frequencies up to 300 kHz. It accommodates selectable encoder supply voltages of 5 V, 12 V, or 24 V DC with a maximum current delivery of 500 mA.
Hardware Configurations and I/O
The board is manufactured in distinct hardware variants, including GP/GPC and SP/SPC configurations. The GP/GPC version features two synchronization inputs operating at 24 V DC and two analog outputs ranging from plus-minus 10 V DC with 12-bit resolution and plus-minus 1% accuracy.
Alternatively, the SP/SPC version replaces these analog interfaces with four binary inputs and four binary outputs rated at 30 V DC and 100 mA. Both variants communicate via a parallel backplane I/O connector within an ABB CDC board rack.
System Integration and Power
Internal timing is driven by a 32 MHz clock frequency to ensure precise signal processing and rapid feedback generation. The module operates on a primary internal power supply of +24 V DC.

Frequently Asked Questions
Q: How do I determine whether a specific YPH108B unit has analog or binary interfaces? A: Check the full type designation suffix on the module label; GP and GPC variants include analog outputs and synchronization inputs, while SP and SPC variants incorporate binary inputs and outputs.
Q: What are the compatible encoder channel signals for this board? A: The module processes standard incremental encoder channels A, B, and Z for each connected encoder.
