Product Description
The IS215ACLAH1AL model is an Application Control Layer Module (ACLA) designed by General Electric as a microprocessor-based master controller that performs numerous duties over communication networks, including but not limited to ISBus and Ethernet networks. The ACLA model can be used in drive applications; when used in drive applications, the P1 connectors on this model will plug directly into the Control Assembly Backplane Board. The ACLA model is one of two ACL models; this ACL model has two serial communication ports labeled COM1 and COM2 and a 10BaseT Ethernet port.
The hardware features that are equipped on the IS215ACLAH1AL model are Ethernet, two serial ports, a bus target interface, a peripheral component interconnect (PCI) controller, up to 4 MB of flash memory on a basic input/output system, a level 2 cache with a byte level of 128 K, a central processing unit, and up to 8 MB of dynamic random access memory (DRAM). Another feature of this model is the Dual-Ported RAM (DPRAM); the DPRAM can only be used with models that do not use the ISBus. There are additional hardware features that can be used with the ACLA model; those hardware features are a serial cable labeled 336A3582P1 and a serial adapter cable labeled 336A4929G1.
All of the above information on the IS215ACLAH1AL is taken from the GEI-100434A Application Control Layer Module Instruction Manual. For more information on the ACLA model, refer to that manual and any available GE documentation.
