Product Summary

The IS215ACLEH1B is a microprocessor-based Application Control Layer Module for the EX2100e series. This board executes critical control duties over ISBus and Ethernet networks. It occupies two half-slots in the EX2100 exciter rack. The B-rated revision delivers a specific functional upgrade for demanding applications. This module manages I/O points, internal Booleans, and non-volatile flash memory for Innovation Series drives.

Expert Technical Evaluation & Performance Review

Microprocessor and Memory Architecture

The IS215ACLEH1B uses a PCI controller to manage all inputs and outputs. This controller handles configuration transfers to the PCI bus. It also manages a variety of memory functions effectively. The board includes a 128 KB L2 Cache for performance. This cache operates with a 152 NC cache line setting. It fills the line between the L1 and L2 cache efficiently. The board also features a flash memory device for data storage. This device is known as Device 1 on the local bus. Access to this memory occurs only in byte mode.

Communication and Network Interfaces

This module uses an Ethernet connection for network communication. The BIOS function on the board initializes this connection via IRQ 5. The physical Ethernet port is a 10baseT RJ45 jack. You will find this jack on the front panel of the board. This setup allows for standard network integration. The board also communicates over the ISBus network. This dual-network capability makes the module very versatile.

Hardware Design and Component Strategy

The IS215ACLEH1B follows the standard EX2100 series voltage suppression strategy. The modular assembly accepts a unique series of components. These include various capacitors, resistors, and transistors. The design also uses diodes and specialized integrated circuits. This component strategy ensures reliable voltage management. The board receives a conformal PCB coating for protection. The product number confirms this coating and the B-rated revision.

Procurement and Application Alignment

The functional product number provides key hardware details. The “ACLE” acronym identifies it as an Application Control Layer Module. The “IS215” prefix indicates domestic manufacture and EX2100 series assembly. This grouping helps you select the correct replacement part. The IS215ACLEH1B is not the original H1 parent module. It uses a singular B-rated primary functional revision. This revision makes it distinct for specific system upgrades. Use this module for applications requiring enhanced control logic.
