Allen-Bradley 1336-BDB-SP21C

The Allen-Bradley 1336-BDB-SP21C gate drive board is engineered for use with 1336 Plus, Plus II, Force, and Impact adjustable frequency drives, providing reliable performance at 575 Volts AC with a robust 30 Horsepower output across a frequency range of 50 to 60 Hertz. Strategically positioned between the main control board and chassis, this component facilitates power connections through terminal block TB1, supporting drives rated from 1 to 30 Horsepower across various voltage levels. For seamless transitions, it can be replaced by the 1336-BDB-SP21D board. It is essential for users to ensure the bus voltage is zero and the power is disconnected before replacement, especially when troubleshooting EE INIT READ 53 errors or resolving issues with absent bus voltage despite power being applied.
