ABB | BRC-100 P-HC-BRC-10000000 | BRC100 Harmony Bridge Controller

Product Description:

The IEMMU11, IEMMU12, IEMMU21, and IEMMU22 are module mounting units used to house standard INFI 90 ® OPEN system modules and the BRC-100 Harmony Bridge Controller module of the Symphony™ Enterprise Management and Control System in system cabinets. The mounting units are available with a front or rear mount card chassis and are available with or without primary power distribution.

The backplane is a multilayer printed circuit board assembly containing electronic components, dipshunt sockets, connectors, and jumpers. In most cases, the mounting unit provides direct I/O cable coupling to the modules. The exception to this is when a BRC-100 Harmony Bridge Controller module is installed in the MMU. 

A processor bus adapter (PBA) must be installed on the back of the module mounting unit when a BRC-100 Harmony Bridge Controller module is used. The PBA is necessary to connect the controller module to Hnet for communication with a Harmony I/O system. The Hnet bus is the communication path between a BRC-100 module and Harmony I/O blocks.
