THEORY OF OPERATION

INTRODUCTION

This section expands on the description of the internal operation of the EX7000 and explains how to best use them. A full understanding of this operation is not required to operate and use the EX7000. A functional block diagram is provided below.

SYSTEM OVERVIEW

Using the drivers provided with the EX7000, commands are issued from the host PC to the Digital Controller Board (DCB). The DCB, in turn, controls the operation of the RDBs. Up to eight RDBs can be controlled by one DCB, making the EX7000 capable of providing up to 576 high-current relay control drivers, 96 very high-current drivers, and 256 parallel I/O ports. This is illustrated in Figure 5-1.When multiple RDBs exist in an EX7000 system, a rotary switch on the RDB is used to set a unique address for each RDB.
