GENERAL ELECTRIC 269PLUS-D/O-211-100P-120VAC MOTOR MANAGEMENT RELAY

269PLUS-D/O-211-100P-120VAC is a motor relay system that is a part of the 269 Plus Motor Management

Relay series, distributed by GE Multilin. The purpose of this motor relay system is to provide protection to

3-phase motor systems as they function near their operational limits. This device uses current transformers to

monitor electrical characteristics of the motor. This drive uses 100 Ohm platinum resistance thermal detectors

(RTD) for temperature monitoring. Key features of the drive include, but are not limited to, custom curve selectability, motor statistical

records, speed switch input, differential relay input, 10 RTD inputs, the single-shot emergency restart feature, an RS485

communications port, unbalance input to thermal memory, the start inhibiting feature, and the spare input.

There are four primary output relays on the motor relay system. The primary trip relay controls power to the external

device. There are also two auxiliary relays and a primary relay, which are designed for communication with external

devices. These outputs can be programmed to either have a latched or non-latched configuration. The motor relay

system also has analog outputs, which are designed to be able to communicate information such as motor current,

hottest stator RTD values, bearing RTD or, CT secondary current. The front panel of the system has a variety of indicators

for user interaction. It contains a 48 character alpha-numeric LCD display for critical information such as current values, alarms, and

programming. Additionally, the display has a total of five LED indicators. The first four correspond to

the relay output conditions. The fifth LED corresponds to self-test alarm conditions.
