169PLUS-120N-125VDC

Product Description

The 169PLUS-120N-125VDC is a highly configurable Motor Protection System produced by General Electric Multilin. The relay comes with basic setpoints programmed for a large motor system, and users can further adjust these setpoints upon receiving the relay or as they become more familiar with the data produced by the relay. 

While users can manage their motor system with fairly few connections to GE Multilin’s 169PLUS-120N-125VDC, the unit does offer a wide array of ports to diversify and customize the relay’s functions. Some of these connections include:

• Auxiliary Relay Contacts: These two contacts provide additional sets of NO/NC connection and work independently of other contacts. The relays can be configured as non-fail safe or fail safe and as latched or unlatched. They can be used to active alarms or trip functions, and can trip devices that aren’t simply the motor.

• RTD Sensor Connections: Users can connect up to six resistance temperature detectors for monitoring values such as stator motor temperature, hottest historical temperature, and ambient air temperature. The data gained from these connections is then used by the relay to schedule optimal cooling processes.

• Analog Output Terminals: These two terminals can be configured using the relay’s setpoint system. It enables connection to chart recorders, remote meters, programmable recorders, and/or computer loads.

• Emergency Restart Terminals: This connection type can override trips within the system and forcibly restart the motor. 

These connections increase the overall versatility of the system and can further shield motor components from harm during operation.
