The NSL-HC04 is a dedicated stand-alone hoist controller designed for direct-controlled chain hoists. This unit supports connections to up to 4 motor hoists simultaneously. Its primary feature is the link option for up/down and E-STOP buttons, enabling centralized control of multiple hoists with synchronized operation. The controller includes MPA (Manual Phase Align) circuit breakers that protect all outputs, disconnecting all three phases and neutral in emergency situations. It features a 3x32A, 5-wire mains input with CEE (3P+N+E) 32A inlet plug. Multiple units can be linked in master/slave configuration via the link in/out ports on the rear panel for expanded control capabilities across larger rigging systems.
