Product Introduction
ABB YPT111A 61205055 Extended I/O Terminal Board is a field terminal interface used with the ABB YPQ111A Extended I/O Board, mainly for connecting field instruments to the I/O system through two 40-pin flat cables. For plants running legacy ABB control cabinets, this board is usually purchased during planned maintenance, urgent troubleshooting, or terminal-side replacement when wiring reliability and part-number accuracy directly affect restart time.
Before ordering, please check the installed board label, cabinet drawings, and spare parts list carefully. The codes YPT111A, 61205055, 3AFE61205055, and 3AFE61208976 may appear in different maintenance records or BOM files, and the configuration with or without the UM108 profile module should also be confirmed. If your site is under shutdown pressure, send us the board photo, required quantity, and destination country so we can verify stock and packing details before shipment.

Technical Notes
The YPT111A terminal board has two separate 24 VDC power supply inputs:
| Power Input | Function |
|---|---|
| +24V IN / BI | For binary inputs |
| +24V IN | For YPQ111A when used as remote I/O |
The original terminal assignment includes X1 pins 1, 3, 5, and 7 for the binary input supply and X1 pins 9, 11, 13, and 15 for YPQ111A remote I/O supply. When voltage inputs are chained from one YPT111A to another YPT111A or YPT111B, the available 24 VDC inputs can be used as outputs depending on the wiring arrangement.
Important wiring check:
Pins 9, 11, 13, and 15 of connector X1 should not be used when the YPQ111A board is installed as local I/O. In that configuration, the YPQ111A is connected to the YPP110A Application Controller through the parallel backplane I/O connector instead of the serial bus.
