IS215 Full Catalog & Functionalities (SKU List)

The following SKUs represent verified, commonly stocked modules within the GE IS215 series, classified by functional category. Each module is compatible with the Mark VIe control system unless otherwise noted.

Controller & Processor Modules

• IS215UCUEH2AB: Universal Controller Unit, Ethernet, Mark VIe TMR/Simplex CPU board with dual IONet ports and real-time OS.
• IS215UCUEH2A: Earlier revision of the UCUEH controller; functionally equivalent to H2AB with minor firmware differences.
• IS215UCVEH2A: Universal Controller Unit variant with enhanced voltage regulation circuitry for high-ambient installations.
• IS215ACLEH1A: Analog Control Logic board; handles closed-loop PID control execution within the Mark VIe R-type rack.

Digital Input (DI) Modules

• IS215DSVOH1A: Digital Servo Output board; provides 4-channel servo valve drive outputs for turbine fuel control.
• IS215DSCBH1A: Digital Signal Conditioning board; conditions discrete contact inputs from field devices.
• IS215DSCAH1A: Digital Signal Conditioning board, alternate revision; used in simplex Mark VIe configurations.
• IS215TRLYH1B: Relay Output board; 16-channel dry-contact relay outputs for trip and alarm circuits.

Analog Input (AI) / Mixed I/O Modules

• IS215AEPAH1A: Analog & Ethernet Processor board; integrates analog signal acquisition with IONet communication.
• IS215VTURH1B: Vibration and Speed Monitoring board; processes proximity probe and accelerometer inputs for turbine shaft monitoring.
• IS215VTURH2B: Vibration Monitoring board, revision 2; expanded channel count and improved noise rejection.
• IS215PTURH1B: Protection and Trip board for turbine overspeed and vibration trip logic.

Communication & Network Modules
