[Precautions for use]
This module is the core board of the DCS controller. When replacing it, it must be confirmed that the model is completely consistent (3BHE021887R0101) and cannot be mixed with safety CPUs (such as UFC721BE101) or ordinary I/O modules. When it comes to excitation control and high-voltage frequency converter applications, debugging requires qualified engineers to operate and complete control logic interlock verification. Due to the discontinuation of this model, the market is dominated by inventory and disassembled parts. It is recommended to prioritize confirming the reliability of spare parts sources and verifying system compatibility (AC 800M/AC 800M HI/800xA platforms) when purchasing.
