Expert Buying Guide

• Verify your generator type: This module works with synchronous generators from 1 MW to 500 MW.
• Check your field current range: The module measures up to 10 A. Use an external shunt for higher currents.
• Communication planning: Use PROFIBUS DP for fast control loops. Use Modbus RTU for monitoring only.
• Installation tip: Keep field wiring separate from signal wiring. This prevents noise interference.
