Regarding IS215ACLEH1B

This IS215ACLEH1B modular assembly product from General Electric was originally designed and manufactured specifically for the EX2100 or EX2100E excitation control system series. As a member of the EX2100 series, this IS215ACLEH1B product seems to have been customized to meet the various installation requirements of the General Electric standard VME rack-mounted structure, as its special assembly method uses a metal mounting panel specially designed for this structure. This IS215ACLEH1B device is not actually the original application control layer module manufactured for the General Electric EX2100 or EX2100E series. Because the latter should be regarded as the IS215ACLEH1 parent application control layer module that does not use the single B-level main function revision of this IS215ACLEH1B product.

Hardware prompts and specifications

The IS215ACLEH1B model belongs to the EX2100e series and serves as an application control layer module, typically based on a microprocessor. The main purpose of this board is to perform multiple tasks through communication networks such as ISBus and Ethernet. After installation, this board will occupy two half slots of the EX2100 exciter board frame or the innovative series driver. As a standard product of the General Electric EX2100 or EX2100E series, the voltage suppression and limitation strategy of the IS215ACLEH1B device involves its special modular components, which are compatible with a series of unique standardized hardware components. Including but not limited to various types of EX2100 series capacitors, resistors, transistors, diodes and application-specific integrated circuits (ics). The ACLE board will also be located inside the control cabinet. It has many different software functions, including but not limited to the following:

I/O points and internal Boolean coercion

Application control of the innovative series of drivers

Non-volatile flash memory

Online application configuration loading

Control block

The IS215ACLEH1B motherboard uses an Ethernet connection, and this connection uses IRQ 5 initialized by the BIOS function on the motherboard. The Ethernet connection on the ACLE motherboard is a 10baseT or RJ45 interface, which is located on the front panel of the ACL motherboard. As a microprocesses-based controller, this motherboard features a Peripheral Component Interconnect (PCI) controller for managing different inputs and outputs, configuration transfers to and from the PCI bus, and various memory functions. The IS215ACLEH1B model also features a 128 KB L2 cache, which is used and controlled by the PCI controller. This cache is set to a 152 NC cache line, filling the cache line between the L1 and L2 caches. Another feature of the ACLE motherboard is that it has a flash memory device, which is located on the local bus side of the target interface and is called Device 1. It can only be accessed in byte mode. Given that the original printed instruction manual materials of this IS215ACLEH1B device are generally less available online, the IS215ACLEH1B functional product number can actually serve as a powerful source of information on the hardware components and component specifications of the IS215ACLEH1B motherboard. The IS215ACLEH1B functional product number indirectly encodes many related hardware details in a series of GE-made functional naming blocks, starting from the initial dual-function IS215 block, which represents the domestic manufacturing location of this IS215ACLEH1B device and its special EX2100 series modular components. Some other related hardware details in the IS215ACLEH1B functional product number include the ACLE functional product abbreviation of this IS215ACLEH1B motherboard, its first group of EX2100 series product groups, its conformal PCB coating, and ultimately its B-class major functional product version.
