The ABB 3BHE021887R0101 UBCC717BE101 serves as the"brain"of ABB ACS 800 high-voltage variable frequency drives(VFDs),integrating logic control,parameter storage,and multi-protocol communication in a single industrial-grade board.Designed exclusively for ACS 800 series VFDs(500kW to 5000kW),it ensures seamless operation in demanding environments like steel mills and power plants,where reliability and compatibility are critical.
Its robust EMC(Electromagnetic Compatibility)design resists RFI and EFT interference,preventing parameter loss even amid grid fluctuations or high-voltage equipment proximity.The board supports three key communication protocols—PROFIBUS DP,Modbus,and ABB DrivesLink—enabling direct integration with DCS systems(e.g.,ABB AC 800M,Siemens PCS7)without additional gateways,simplifying setup and reducing integration time.
Built-in diagnostics(power,communication,I/O fault indicators)and non-volatile EEPROM(100,000 write cycles)enhance maintainability:parameter transfer between old and new boards takes minutes,eliminating the need for tedious reconfiguration.With an MTBF of 200,000 hours and industrial-grade temperature/humidity tolerance(0°C to 60°C,5%to 95%RH),the 3BHE021887R0101 UBCC717BE101 delivers long-term reliability,making it the preferred replacement for aging ACS 800 VFD control boards.
