The ABB YPQ202A YT204001-KB, also cataloged as the YPQ202A I/O Board, provides physical input and output interface circuitry for ABB Advant OCS/800xA control hardware, with status indication and resistive network elements.

Model Reference

The supplied identification combines the product model YPQ202A with spare model YT204001-KB. The available data does not provide an official decoding of either model designation, so no individual suffix function is assigned.

Hardware Specifications

I/O Circuit Characteristics

The YPQ202A YT204001-KB is identified as a PC-based I/O board with stand-off mounting, LED status indicators, and a resistive network. The supplied electrical data specifies an input voltage of 24 VDC or 110/230 VAC and a typical output voltage of 24 VDC.

The listed output current is 0.5 A per output channel. The number of output channels is not provided and should not be inferred from the model designation.

ABB Control System Interface

As an ABB control hardware component, the board is associated in the supplied information with the Advant OCS/800xA environment. I/O density, backplane communication method, terminal allocation, channel isolation, and firmware compatibility are not specified in the supplied data.

The board should therefore be matched against the target rack, controller configuration, wiring diagram, and applicable ABB documentation before replacement or commissioning.

Ordering Information

Installation and Wiring Guidelines

• Verify the complete YPQ202A YT204001-KB identification before installation.
• Confirm the required input supply type before applying power because the supplied data lists 24 VDC or 110/230 VAC.
• Check the actual terminal assignments against the applicable ABB wiring documentation.
• Confirm output loads remain within the specified 0.5 A per output channel.
• Do not infer the total board output capacity from the per-channel rating.
• Install the board using its specified stand-off mounting arrangement.
• Prevent conductive debris, loose hardware, and contamination from contacting exposed PCB circuitry.
• Keep power wiring separated from sensitive signal wiring where practical.
• Verify grounding and cabinet bonding according to the control system installation requirements.
• Check LED status indicators during commissioning against the applicable ABB system documentation.
• Do not connect or disconnect field wiring while energized unless the applicable ABB hardware documentation explicitly permits the operation.
• Verify rack and system compatibility before applying the board to an Advant OCS/800xA installation.
