The Base Control Module is the controller of the C445 Motor
Management Relay system. It provides motor protection and
control algorithms and various motor data for monitoring.
This module is equipped with native digital inputs for field
wire control and outputs for motor control and protection.
It also provides communication card options and USB
connectivity for real-time data on the health and status of
the motor.
Base Control Module provides the slot for optional
communication cards, the connectors for digital inputs and
outputs, the optional RS-485 Modbus connector, the
connector for powering the system, the USB port and the
DIP switches (see
