ABB / M10x Intelligent Motor Management
ABB M102-M Motor Control and Protection Unit
Modbus RTU motor control and protection unit with current and voltage measurement for 0.24-63 A applications.
Product Overview
Integrated motor control, protection and measurement
ABB M102-M is the Modbus RTU version of the M102 motor control and protection unit. It combines current and voltage measurement with control, protection, alarm, trip and operating-statistics functions.
The integrated current-transformer range is 0.24-63 A. Official ordering options include 24 Vdc, 110 Vac and 240 Vac supply variants, so the supply must be selected from the complete order number rather than inferred from M102-M alone.
