Description
Product Overview
ABB 1SFB536068D1011 is a soft starter control board, and its alternative marking is PSPCB-LV/T. This board matches ABB PST and PSTB series low voltage soft starters, and it commonly works with PST105-600-70 and PSTB105 units. It runs core control logic for soft start and soft stop, and it sends optical isolation trigger signals to thyristors. Besides, it connects the local keypad and optional communication plug-in modules, so it acts as the central signal and control core of the soft starter.
