IS200RCSAG1ABB RC Snubber Board – GE EX2100 Series
The IS200RCSAG1ABB is a passive RC snubber board from GE Industrial Systems. It belongs to the EX2100 Excitation Control System. This board protects SCR and diode modules from high-voltage transients. It absorbs excess energy through resistor-capacitor networks. It also reduces EMI and prevents component stress. This board is a modified version of the parent IS200RCSAG1. It carries three revisions: A, B, and B grades. It fits 1800A and 1000A frame Innovation Series nonregenerative drives.

Key Features & Protection Capability
- Snubber Circuits: Two identical RC networks per board – one for SCR, one for diode.
- Transient Suppression: Limits dv/dt and dampens voltage spikes from inductive loads.
- EMI Reduction: Minimizes electromagnetic interference for system stability.
- Passive Design: No active components, fuses, test points, or LEDs. No user adjustments.
- Mechanical Support: Mounts directly on SCR/diode modules for compact assembly.
- Fixed Configuration: No movable jumpers; factory drilled holes for installation.
Application Data & Typical Use
- Primary Role: Protects power semiconductors in high-power excitation bridges.
- Compatible Frames: 1800A and 1000A Innovation Series nonregenerative sources.
- Noise Isolation: Provides noise isolation for gate drive circuits.
- System Integration: Works within GE EX2100 excitation control systems.
- Passive Support: Dedicated snubber interface, not a diagnostic or control module.
Installation, Maintenance & Compatibility
- Mounting: Four factory-drilled holes for secure installation.
- No Calibration: Fixed parameters – no field adjustments needed.
- Maintenance: Minimal; periodic visual inspection recommended.
- Compatibility: Direct replacement for IS200RCSAG1 variants. Fully compatible with GE EX2100 and Mark VI systems.
Environmental & EMC Performance
- Temperature Range: -35°C to +65°C, suitable for harsh industrial environments.
- Coating: Normal PCB coating protects against dust and moisture.
- EMC Compliance: Minimizes conducted and radiated emissions.
- Reliability: Reduces electrical overstress and extends component life.
