Installation & Setup Guidance
The Woodward 8440-1945 is designed for cabinet mounting. Its sheet metal housing lacks an LCD, so operators should configure it remotely via expansion boards and analog I/O. Follow these guidelines for proper setup:
- Mount the module securely in a clean, dry cabinet with adequate ventilation.
- Connect analog I/O and discrete expansion boards as per the wiring diagram for your application mode.
- Verify the primary setting range (50–650,000 Vac) and current range (1–32,000 A) match your generator parameters before energizing.
- Use the P1 series' reduced interface count to simplify connections in space-constrained panels.
Selection Guide & Purchasing Advice
When purchasing the Woodward 8440-1945, confirm compatibility with your existing control system. This module is a direct equivalent to the EasYgen-3400-1-P1. For reliable supply and competitive pricing, choose PLC Source PRO (available at ubest101). Ensure your system can support the analog I/O and expansion board requirements for your chosen application mode.
