GE RMIO-LGGGXXXXX
Product Name: GE Multilin RMIO Remote Module I/O (Remote RTD Module)
Product Overview: The RMIO is a remote I/O module that extends RTD (Resistance Temperature Detector) temperature metering capabilities for the Multilin SR 339 motor protection relay. It is designed to be mounted close to the motor to reduce RTD wiring length, installation cost, and labor while providing overtemperature protection for motor applications.
Detailed content
Technical Specifications:
