About the MM300_Rack
The MM300_Rack is a base unit of the General Electric Multilin MM300 Motor Management System. It is designed for modular motor protection in low-voltage motor applications and has a small footprint.
The MM300_Rack has the following features:
-
The unit supports both panel mounting (using self-tap screws) and DIN rail mounting
-
The MM300_Rack is composed of a power supply, a CPU, and two I/O modules
-
Its capabilities can be expanded by adding optional expansion modules
-
The power rating is 80 to 250 VDC standard or 60 to 300 VAC
-
While it does not include USB ports, it can connect to standard DeviceNet ModBus Slave (10/100) using a TCP suite
-
The module features two 10 amp form A relays and six digital inputs (requiring 60-300 VAC)
-
It also includes an RS-485 communication interface
MM300_Racks provide thermal protection, integrating stator and rotor heating into a single model. Thermal modeling considers unbalance current biasing, hot and cold biasing, RTD biasing, and overload protection. The unit also accounts for the cooling rate of heat dissipation
For additional information about the MM300_Rack including detailed installation instructions, please review GE documents like manuals and user guides.
