GE IS215ACLEH1B ACLE Module Mark VI EX2100 Control

Product Overview

The GE Energy IS215ACLEH1B (Functional Acronym: ACLE) is a high-performance Application Control Layer Module designed for General Electric's Mark VI Speedtronic Gas Turbine Control Systems and EX2100 / EX2100e Excitation Control Systems. Engineered for critical industrial control applications, this microprocessor-based controller manages real-time turbine control logic, subsystem coordination, complex communication protocols, and system diagnostics.

Featuring an "IS215" domestic special modular assembly prefix, the IS215ACLEH1B is built with a dual-slot metal faceplate tailored for standard GE VME rack structures and control cabinets. Operating with a 125 V DC input voltage and 24 V DC output, it incorporates a high-speed PCI controller, 128 KB L2 cache, 10BaseT RJ45 Ethernet communication, non-volatile flash memory, and an array of front-panel LED status indicators. Weighing approximately 0.57 kg (1.25 lbs), this Grade B functional revision module delivers robust online application loading and real-time control block processing across demanding energy environments.

Core Technical Advantages

• Advanced Microprocessor & PCI Controller Architecture: Equipped with an onboard CPU, PCI controller, and 128 KB Level 2 cache to optimize data transfers and high-speed input/output processing.
• Comprehensive Network & Bus Connectivity: Features 10BaseT RJ45 Ethernet (IRQ 5 initialization via BIOS) for seamless communication over ISBus networks, SCADA systems, and central control hubs.
• Flexible Software & Logic Capabilities: Supports online application configuration loading, non-volatile flash memory storage, control block execution, and real-time forcing of I/O points and internal booleans.
• VME Rack & Dual-Slot Integration: Engineered with a specialized installation faceplate that occupies two half-slots in standard EX2100 exciter board racks or Innovation Series drives.

Technical Specifications

Installation & Handling Guidelines

• ESD Protection & Static Safety: Always handle the ACLE board using a grounded wrist strap and static-safe equipment to avoid damaging onboard microprocessors and flash memory ICs.
• VME Rack Slot Insertion: Align the metal faceplate guide rails carefully into the two half-slots of the EX2100 exciter rack or Innovation drive cabinet before securing the faceplate retaining screws.
• Ethernet & Cable Connection: Connect standard RJ45 Ethernet cabling directly to the front-panel 10BaseT port, ensuring correct pin alignment and cable strain relief within the cabinet.
