1. Product Description
The IS200EDCFG1A acts as a bridge between the SCR bridge and the control panel, measuring field current and voltage to enable real-time adjustment of excitation systems. Key features include:
- Dual Feedback Measurement: Simultaneously monitors field current (via DC shunts) and field voltage (across bridge terminals), providing accurate data for excitation control.
- Fiber-Optic Isolation: Uses high-speed fiber-optic links (plastic or hard-clad silica) to transmit signals to the EISB board, ensuring voltage isolation and immunity to electromagnetic interference.
- Flexible Voltage Scaling: Seven selectable settings for field voltage feedback, allowing adaptation to different bridge configurations.
- Built-in Power Management: Converts external 24V DC power to +15V, -15V, and +5V outputs for board operation, with a green LED indicator for power status.
