The ABB AIBP-51 68257913 is an I/O unit power card, mainly used for the interface module of the 3500 frame. It supports Bentley's proprietary protocol for frame configuration and calling up information from the unit, and must be placed in a slot in the frame (close to the power supply). AIBP-51 has an RS-232 serial interface on the front panel, which can be connected to the host for data acquisition and frame configuration. The baud rate is 38.4K and the cable length requirement is 30 meters. There is an RS-232/RS-422 serial interface on the rear I/O module, which can also be connected to the host for data acquisition and frame configuration. The baud rate is 38.4K and the cable length is: 30 meters for RS232 and 1200 meters for RS422. The RS422 interface also enables multiple 3500 frames to communicate with the 3500 host software in a chain connection.

In addition, AIBP-51 plays an important role in the frame interface module. Although it is not an important part of the monitoring path, it has an auxiliary role in the normal operation of the entire monitoring system.
