Technical Specifications

The GE IS215ACLEH1A is a master controller powered by a microprocessor. It handles numerous tasks across Ethernet and other communication networks. This module completely replaces the older IS215ACLAH1A (ACLA) in EX2100 applications.

General Specifications

Hardware Architecture

The IS215ACLEH1A consists of two printed circuit boards assembled as one unit.

Note: This module is not designed for user disassembly. Do not attempt to separate the carrier board from the PC/104-Plus board.

Processor Board Specifications

Memory Configuration

Communication Interfaces

Compatible Backplanes and Racks

The IS215ACLEH1A works with these EX2100 control racks.

DPRAM Arbitration

The IS215ACLEH1A communicates with the IS200DSPXH1_ Digital Signal Processor board through 32-bit DPRAM. Hardware automatically resolves contention when both boards access the same address simultaneously. The maximum wait condition is 100 ns.

Installation Guidelines

Follow these steps to install your General Electric IS215ACLEH1A module correctly.

1. Power Down System – De-energize all EX2100 rack power sources.

2. Identify Slots – Locate two adjacent slots for the IS215ACLEH1A.

3. Insert Module – Slide module into slots until fully seated.

4. Secure Board – Tighten faceplate screws firmly.

5. Connect Ethernet – Attach 10BaseT cables to ENET1 and ENET2 ports.

6. Connect Serial – Attach COM1 or COM2 cables as needed.

7. Apply Power – Energize system and monitor LED indicators.

8. Download Code – Use Toolbox to download runtime code via ENET1.

Do not exceed 45°C operating temperature. The IS215ACLEH1A requires proper ventilation in the control cabinet.

Frequently Asked Questions (FAQ)

1. What is the difference between IS215ACLEH1A and IS215ACLAH1A?
The IS215ACLEH1A (ACLE) completely replaces the older ACLA module in EX2100 applications. However, it does not replace ACLA in Innovation Series applications.

2. What operating system does the IS215ACLEH1A use?
The IS215ACLEH1A runs the QNX operating system. This real-time OS is optimized for industrial control applications.

3. How many slots does the IS215ACLEH1A occupy?
This module occupies two complete slots in standard EX2100 control racks. Plan rack space accordingly.

4. Can I disassemble the IS215ACLEH1A to access individual components?
No. The IS215ACLEH1A is supplied as an assembled unit. It is not designed for user disassembly of the carrier board or PC/104 board.

5. What manuals cover the IS215ACLEH1A?
Refer to GEI-100434 (Application Control Layer Module Manual) and GEH-6632 (EX2100 Excitation Control User’s Guide) for complete documentation.

6. What is the purpose of the RESET button on the faceplate?
The RESET button cures potentially fatal fault conditions. It performs necessary resets of the application control layer module.

Why Choose This Model?

The General Electric IS215ACLEH1A offers powerful application control for EX2100 excitation systems. Its 486 100MHz processor handles complex control algorithms efficiently. The QNX operating system provides real time performance for critical excitation tasks. The two 10BaseT Ethernet ports support redundant network connections. The two RS-232 serial ports connect to configuration and debugging tools. The 128 MB DRAM and non-volatile compact flash store application code and data reliably. The Phoenix BIOS ensures industry standard boot and hardware initialization. The DPRAM interface communicates directly with DSPX digital signal processor boards. The comprehensive LED indicators provide clear module status at a glance. Choose this IS215ACLEH1A for EX2100 simplex or redundant regulator control, thyristor control, and excitation applications requiring a powerful application control layer module.
