Description

The GE Multilin SR489-P5-LO-A20-E is a compact, cost-effective draw-out protection system designed for small to medium-sized synchronous/induction generators (25–60 Hz). It integrates advanced protection, monitoring, and metering with a 5A phase CT input (P5), low-range control power (LO: 24–60V DC/20–48V AC), 4–20mA analog outputs (A20), and an enhanced display/keypad (E module). Ideal for primary/backup protection in cogeneration and industrial applications, it ensures reliable generator operation while minimizing downtime.

Features

  • Comprehensive Protection:
    • Stator differential (dual-slope CT saturation immune), 100% stator ground fault (third harmonic adaptive), loss of excitation (negative mho), reverse power, and breaker failure detection.
    • Backup phase distance protection with transformer compensation.
  • Advanced Monitoring:
    • 12 RTD inputs for stator/bearing temperature (voting feature for redundancy).
    • 4 analog inputs for vibration monitoring (0–20mA/4–20mA configurable).
    • Real-time metering: current, voltage, power, energy, frequency, and power factor.
  • Flexible Communications:
    • RS232, 2x RS485 (Modbus RTU/DNP 3.0), and optional 10BaseT Ethernet (Modbus TCP/IP).
    • IRIG-B time synchronization for event logging (1ms accuracy).
  • User-Friendly Interface:
    • 40-character sunlight-readable LCD with keypad for local configuration.
    • 22 LED indicators for relay status, generator health, and output relay states.
  • Rugged Design:
    • Draw-out construction for quick maintenance (minimized downtime).
    • Harsh environment conformal coating option for chemical resistance.

Technical Specifications

  • Current Inputs (P5):
    • 5A CT secondary, 0.02–20x CT range, ±0.5% accuracy at <2x CT, ±1% at >2x CT.
    • CT withstand: 80x rated current (1s), 40x (2s), 3x continuous.
  • Voltage Inputs:
    • VT ratio 1.00–240.00:1, 200V AC (phase), 100V AC (neutral), ±0.5% accuracy.
    • Max continuous voltage: 280V AC.
  • Power Supply (LO):
    • 24–60V DC / 20–48V AC (48–62Hz), 25VA typical, 45VA max.
  • Analog Outputs (A20):
    • 4–20mA, ±1% accuracy, 1200Ω max load.
  • Output Relays:
    • 6 Form C contacts (10A/30VDC resistive, 10A/120VAC resistive), 10ms operate time.
  • Communications:
    • RS485: 300–19,200 baud, isolated at 36Vpk.
    • Ethernet (optional): 10Mbps copper, Modbus TCP/IP.
  • Environmental:
    • Operating temp: -40°C to +60°C.
    • Humidity: 95% non-condensing.
    • Altitude: ≤2000m.
  • Certifications:
    • UL508, UL1053, CE, CSA, ISO9001 compliant.
