Description
The GE IS200EPMCH1 is a high-performance expansion module for GE’s Mark VIe turbine control platform. It extends I/O capacity and computational power for critical monitoring/control tasks, featuring dual-redundant Ethernet communication, SIL 3-certified logic processing, and isolated signal conditioning. Designed for harsh industrial environments, it integrates seamlessly with Mark VIe controllers via high-speed backplane links.
Features
- Enhanced Processing: Dual-core PowerPC @ 1.2 GHz with 512 MB DDR3 RAM.
- I/O Scalability: Supports up to 96 channels (mix of analog/digital/RTD via expansion carriers).
- Redundant Ethernet: Dual 1 GbE ports (IEEE 1588 PTPv2 time-sync enabled).
- Functional Safety: SIL 3 (IEC 61508) certified for safety-critical applications.
- Extreme Environment: Operates at -40°C to +70°C (-40°F to +158°F) with 5–95% non-condensing humidity.
- Secure Firmware: Hardware-enforced secure boot + encrypted firmware updates.
- Diagnostics: Real-time health monitoring (voltage, temperature, memory CRC).

Key Applications
- Turbine Control: Real-time monitoring of vibration, temperature, pressure.
- Power Grid Stability: PMU (Phasor Measurement Unit) data acquisition.
- Process Safety Systems: SIL 3 shutdown logic for refineries/chemical plants.
- Renewable Energy: Wind turbine pitch control and condition monitoring.
⚠️ Integration Notes:
- Requires Mark VIe controller (IS200/IS215) as host—cannot operate standalone.
- Firmware must match controller version (ToolboxST v8.0+ recommended).
- Expansion carriers must use CAT6 shielded Ethernet for noise immunity.
- Channel overload protection: Max 40mA per analog input.
