Woodward|8440-1878|Digital Synchronizer and Load Control Module
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.
