Description

The GE 269PLUS-D/O-100P-125VDC is a microprocessor-based digital relay engineered by GE Multilin to deliver complete protection, monitoring, and control for three‑phase AC industrial motors. The 269PLUS-D/O-100P-125VDC integrates advanced thermal modeling, programmable RTD temperature sensing, and customizable overload curves into a single compact unit. The 125 VDC control power input makes this 269PLUS-D/O-100P-125VDC particularly suitable for retrofit projects and legacy DC‑powered substations or industrial plants without requiring voltage conversion. With its drawout (removable) case design, the 269PLUS-D/O-100P-125VDC allows operators to remove the relay for bench testing or replacement without de‑energizing the motor circuit, significantly reducing maintenance‑related downtime. The 100 Ω platinum RTD sensor configuration (100P) provides precise stator temperature monitoring, ensuring thermal protection aligns with actual motor heating conditions. Programming is accomplished via a 12‑key keypad and clear LCD display, eliminating the need for external devices during initial setup or field adjustments.

Applications

Pumping stations – centrifugal pumps, booster pumps, deep‑well pumps, boiler feed pump motors
HVAC systems – chiller compressors, cooling tower fans, air handling unit motors, condenser fans
Conveyor systems – bulk material handling, assembly line conveyors, mining overland conveyors
Compressor stations – air compressors, refrigeration compressors, natural gas pipeline compressors
Fan and blower systems – induced draft (ID) fans, forced draft (FD) fans, ventilation fans
Crushing and milling equipment – rock crushers, grinding mills, pulverizers, shredders
Mixers and agitators – chemical reactors, food processing mixers, slurry agitators
Power generation auxiliary systems – cooling water pumps, coal handling conveyors, ash handling motors
Variable frequency drive (VFD) fed motors – tested with frequencies from 15 to 300 Hz

Features

Drawout case construction – removable chassis allows relay extraction and bench testing without disconnecting power to motor circuit
125 VDC control power – natively accepts 125 VDC supply, ideal for DC‑powered industrial plants and substations without external conversion
100 Ω platinum RTD (Pt100) temperature sensing – direct stator temperature measurement with display accuracy of ±2°C and programmable alarm/trip setpoints from 0–200°C
FlexCurve™ custom overload curve – creates smooth, application‑specific current‑time profiles that match non‑standard motor damage curves
MotorMatch adaptive learning – automatically measures and learns actual inrush currents, acceleration times, cooldown periods, and negative‑sequence current contribution (K‑factor) for site‑optimized protection
Enhanced thermal modeling – combines I²t calculation with RTD temperature feedback; thermal capacity reflects the higher of the two values
Exponential cooldown characteristic – mimics actual motor cooling rates with FLC reduction and running cool time settings
Emergency restart capability – permits single restart after overload trip by clearing thermal memory, essential for production or safety‑critical situations
Comprehensive fault protection suite – includes overload (8 standard curves), locked rotor, rapid trip/mechanical jam, unbalance/single‑phasing, short circuit, ground fault, undercurrent, and stator overtemperature
RS-485 Modbus RTU communication – cost‑effective integration with SCADA, DCS, or PLC systems for remote monitoring and data retrieval

Functions

Continuously measures average and individual phase currents, ground leakage current, RTD temperatures, unbalance ratio, and thermal capacity remaining
Compares measured values against user‑programmed protection setpoints (overload, ground fault, undercurrent, temperature, unbalance, etc.)
Issues alarm or trip commands to the main latched relay, alarm relay, or auxiliary relays when conditions exceed thresholds
Logs last trip cause and pre‑trip values for post‑event fault diagnosis
Records statistical motor data (StatTrac) including running hours, number of starts since commissioning, total trips by type, and total megawatt‑hours
Runs continuous self‑diagnostic checks regardless of motor operational status

FAQ

Q1: What does the model designation 269PLUS-D/O-100P-125VDC mean?
A1: D/O stands for drawout (removable case) version; 100P indicates 100 Ω platinum RTD temperature sensors; 125VDC is the control power supply rating.

Q2: Can the 269PLUS-D/O-100P-125VDC protect motors fed from variable frequency drives?
A2: Yes. The 269PLUS-D/O-100P-125VDC has been tested with VFD and PWM drive currents and frequencies ranging from 15 to 300 Hz.

Q3: What is the advantage of the drawout case design?
A3: The drawout case allows removal of the 269PLUS-D/O-100P-125VDC relay for bench testing or replacement without shutting down the motor or de‑energizing high‑current circuits, thanks to shorting contacts on CT inputs and trip relay outputs.

Q4: Does the 269PLUS-D/O-100P-125VDC require separate programming software?
A4: No. Basic configuration is completed directly via the front panel 12‑key keypad and LCD display. Advanced configuration and firmware upgrades can be performed using EnerVista 269 Setup software via RS-485.

Q5: What is the Emergency Restart feature?
A5: When enabled, Emergency Restart allows the 269PLUS-D/O-100P-125VDC to manually reset and restart the motor following an overload trip by clearing the accumulated I²t thermal memory, useful for production‑critical or safety‑situational restarts.
