The GE Multilin 469‑P5‑HI‑A1‑E‑H is a microprocessor‑based motor protection system from the SR relay family, engineered for comprehensive protection, control, and monitoring of medium and large three‑phase motors. The GE 469‑P5‑HI‑A1‑E‑H combines an advanced thermal model with RTD biasing, customizable overload curves, and single‑CT differential protection. The drawout construction simplifies replacement, while the conformal coating (‑H suffix) ensures reliable operation in chemically corrosive or humid environments. With multiple communication ports and EnerVista software support, the GE 469‑P5‑HI‑A1‑E‑H integrates seamlessly into new and existing control networks.
Pumps, fans, and compressors – continuous duty in power generation, oil & gas, and water treatment
Mills, shredders, and extruders – heavy‑duty processing equipment in mining, recycling, and plastics
Cranes, conveyors, and hoists – material handling with high inertia and frequent starts
Crushers, blowers, and chillers – demanding industrial environments requiring robust protection
Two‑speed and reduced‑voltage start motors – special starting regimes
High‑inertia loads – where motor acceleration time exceeds safe stall time
Advanced thermal model with RTD biasing – dynamically adjusts thermal capacity based on stator RTD feedback; unbalance biasing (K‑factor) accounts for additional rotor heating
Customizable overload curves – 15 standard curves, voltage‑dependent curves, and user‑defined FlexCurves™ for high‑inertia starting
Single‑CT differential protection – supports 6‑CT summing or 3‑flux‑balancing CT configurations
12 programmable RTD inputs – monitors stator, bearing, and ambient temperatures with three alarm levels (alarm, high alarm, trip)
Comprehensive protection suite – overload, short circuit, ground fault, current unbalance, under/overvoltage, under/overfrequency, phase reversal, mechanical jam, acceleration timer, undercurrent, reverse power, power factor, overtorque
Drawout construction – minimizes replacement time without rewiring
Conformal coating (‑H suffix) – protects against humidity, chemicals, and corrosion
Motor Settings Auto‑Configurator – simplifies setup with guided parameter entry
Broken rotor bar detection – advanced Motor Current Signature Analysis (MCSA) for predictive maintenance
Simulation mode – tests relay functionality without external inputs, with pre‑fault and fault condition configuration
Event recorder and oscillography – captures 256 events and up to 64 cycles of waveform data (10 waveforms, 12 samples/cycle)
Data logger – trends up to 16 channels for long‑term monitoring
Flexible I/O – 4 analog inputs, 4 analog outputs, 9 digital inputs (5 predefined + 4 assignable), 6 Form‑C output relays
Field‑upgradeable firmware – supports future enhancements without hardware replacement
Voltage‑dependent overload curves – dynamically adjusts thermal protection during motor acceleration
Executes thermal protection – continuously calculates Thermal Capacity Used (TCU) based on current, unbalance, RTD feedback, and cooling time constants
Provides start supervision – enforces time‑between‑starts, starts‑per‑hour, and restart lockout to prevent excessive starting duty
Performs differential protection – compares phase currents across CTs to detect stator winding faults
Monitors ground fault current – via dedicated ground CT inputs (standard or sensitive 50:0.025 A)
Detects abnormal voltage and frequency – under/overvoltage, phase reversal, under/overfrequency
Captures fault data – records events, oscillography, and data logger trends for post‑fault analysis
Communicates with SCADA/DCS – transmits metering and status data via Modbus RTU, Modbus TCP/IP, or DeviceNet
Simulates operating conditions – tests relay response without external inputs
Q1: What does each suffix in the part number 469‑P5‑HI‑A1‑E‑H represent?
A1: P5 = 5A phase CT inputs; HI = high‑range control power (90–300 VDC / 70–265 VAC); A1 = 4 analog outputs (4–20 mA or 0–1 mA); E = enhanced 40‑character display; H = conformal coating for harsh environments.
Q2: Is the 469‑P5‑HI‑A1‑E‑H still in production?
A2: No. The Multilin 469 series has been discontinued. GE recommends the Multilin 859 or 869 as direct replacements.
Q3: What types of motors can the 469‑P5‑HI‑A1‑E‑H protect?
A3: The 469‑P5‑HI‑A1‑E‑H protects three‑phase medium and large horsepower motors, including high‑inertia, two‑speed, and reduced‑voltage start motors.
Q4: How does the 469‑P5‑HI‑A1‑E‑H handle RTD inputs?
A4: The 469‑P5‑HI‑A1‑E‑H supports 12 programmable RTD inputs (100Ω Pt, 100/120Ω Ni, 10Ω Cu) for monitoring stator, bearing, and ambient temperatures with alarm and trip levels.
Q5: What communication protocols does the 469‑P5‑HI‑A1‑E‑H support?
A5: The 469‑P5‑HI‑A1‑E‑H supports Modbus RTU (RS232/RS485), Modbus TCP/IP (optional Ethernet), and DeviceNet.
