PRODUCT INFORMATION
Product Overview
The General Electric 269PLUS-100P-HI is a Multilin motor management relay designed for industrial motor protection. This hardware unit incorporates inputs for 100 Ohm platinum RTDs to track critical machine thermal conditions. It provides dedicated monitoring across connected stator windings, bearing points, and driven equipment. The system receives current signals directly from phase and ground fault CT assemblies.
The integrated front keypad contains dedicated controls for system operation. Pressing the Actual Values key switches the unit into Actual Values mode. Operators inspect all live motor operating parameters directly through this display interface. Pressing the Setpoints key accesses Setpoints mode. Technicians examine and configure alarm limits, trip thresholds, and system parameters.
