Predictive Maintenance: In a UAE power plant, 269PLUS-100P-HI detected a stator winding fault via RTDs 72 hours before failure, saving $450,000 in repairs.
Space Efficiency: 12 RTD channels (vs. 8 industry avg.) reduce chassis slots by 33% in ExxonMobil refineries.
Voltage Resilience: Withstands 400V transients (IEC 61000-4-5), critical for mining crushers exposed to grid instability.
GE Multilin 269PLUS-100P-HI High-Integrity Motor Management Relay
The GE Multilin 269PLUS-100P-HI is a sophisticated motor protection relay engineered for industrial critical motors, delivering advanced thermal, electrical, and mechanical protection in power generation, oil & gas, and manufacturing. With 12 RTD inputs and FlexCurve™ overload customization, this relay prevents motor failures by 92% (GE 2024 field data), outperforming standard relays in harsh environments like offshore platforms and steel mills.
1. Product Overview
The269PLUS-100P-HIacts as a motor health guardian, combining 5A CT inputs for current monitoring with 3-wire RTDs (e.g., PT100) for stator/rotor temperature tracking. Its dual-layer isolation (2,500Vrms) and IP65-rated enclosure withstand voltage surges and dust, while 4 SPDT relays (5A) enable direct control of contactors. Unique SIL 3 certification makes it ideal for safety-critical systems, such as emergency pumps in nuclear plants.

Space Efficiency: 12 RTD channels (vs. 8 industry avg.) reduce chassis slots by 33% in ExxonMobil refineries.
Voltage Resilience: Withstands 400V transients (IEC 61000-4-5), critical for mining crushers exposed to grid instability.
4. Applications & Case Study
Power Generation: Protects GE 7HA turbines’ auxiliary motors at EDF, reducing unplanned stops by 65% through real-time temperature trending.
Oil & Gas: Monitors subsea pump motors for Shell, using locked rotor detection to prevent $2M repair costs in 2024.
Manufacturing: Optimizes BMW’s conveyor motors with load imbalance alerts, cutting downtime by 22% in assembly lines.
Case Study: A Saudi petrochemical plant deployed 50 units on centrifugal compressors. The relay’s thermal memory feature (stores 100 events) reduced troubleshooting time by 40%, achieving 99.99% uptime over 18 months.
5. Competitor Comparison
RTD Density: 12 vs. 8–10 channels, ideal for high-temperature motor fleets.
Safety Rating: SIL 3 vs. SIL 2 for most alternatives, critical for nuclear and offshore applications.
Flexibility: Customizable FlexCurve™ vs. fixed curves, reducing oversizing by 25% in GE’s 9FB turbine retrofits.

6. Selection Recommendations
High-Temp Environments: Opt for 269PLUS-100P-HI (RTD-ready) over 269PLUS-50P (no RTD) in steel mills.
Redundancy: Pair with GE’s 269PLUS-R for dual-channel setups in LNG facilities, meeting API 521 safety standards.
Budget: Choose refurbished units (GE-certified) for non-critical motors, saving 40% while retaining 12-month warranties.
7. Installation & Maintenance
Wiring: Use 18AWG shielded cables for RTDs; torque terminals to 2.0 N·m (GE-recommended).
Calibration: Annual CT tests with GE’s Multilin Toolkit—skip if using factory-calibrated PT100s.
Safety: Power off for 5 minutes before replacement; avoid touching circuit boards to prevent ESD damage.
