Woodward 8440-1878 Digital Synchronizer and Load Control Module

Description

The Woodward 8440-1878 is a microprocessor-based digital synchronizer and load control module designed for three-phase AC generators, integrating synchronizer, load control, and communication functions to enable precise paralleling of up to 32 generators.

Features

  • Combines synchronizer, load sensor, and process control in a single unit.
  • Supports phase match or slip frequency synchronization with voltage matching.
  • Enables automatic soft loading/unloading for bumpless load transfer.
  • Two Ethernet ports: one for unit-to-unit communication, another for remote control via Modbus TCP.
  • Additional RS-485 port for Modbus RTU communication.
  • Compatible with MSLC-2 controls for complex power system management.

Technical Specifications

  • Power Supply: 12/24 VDC (8–40 VDC operating range).
  • Power Consumption: Max. 15 W.
  • Temperature Range:
    • Storage: -40°C to 85°C (-40°F to 185°F).
    • Operation: -40°C to 70°C (-40°F to 158°F).
  • Humidity: 95% non-condensing.
  • AC Inputs:
    • Voltage: 120 VAC or 480 VAC true RMS (Accuracy Class 0.5).
    • Current: 1 A or 5 A true RMS (isolated, Accuracy Class 0.5).
  • Discrete Inputs: Isolated, 12/24 VDC (8–40 VDC range).
  • Relay Outputs: Dry contacts, 2 A resistive load (24 VDC/250 VAC).
  • Analog Inputs: 0–500 ohms, 0–20 mA.
  • Analog Outputs: Isolated ±10 V, ±20 mA, or PWM.
  • Communication:
    • Ethernet: Two ports (Modbus TCP for remote monitoring).
    • RS-485: Modbus RTU support.
  • Physical Specs:
    • Housing: Sheet metal, back panel mounting.
    • Dimensions: 250 x 227 x 84 mm (WxHxD).
    • Sealing: IP20.
    • Weight: Approx. 1,900 g.
