HARDWARE DESCRIPTION

OVERVIEW

An EX7000-OEM consists of the following, constituent parts:

• Digital Controller Board, or DCB

• Relay Driver Board, or RDB (may be one to eight boards depending on the model)

• A ribbon cable to connect the DCB to the RDB

• If multiple RDBs are used, a special ribbon cable with multiple connectors is required

The DCB provides the user interface to the host PC, via a LAN connection, and controls the action

of the associated RDB cards. It is connected to the RDB cards via ribbon cables which run from its

J1 connector to the J1 or J1A connector of the RDB. Also available on the DCB are the LXI

trigger bus connectors, the Digital I/O connectors, and the LXI LAN Reset button.

The RDB is primarily responsible for providing control for the relays attached to the

EX7000-OEM. The board contains connectors for relays, communication to the DCB, power

supply inputs, optional LEDs, and parallel IOs. The remainder of this section will discuss, in

detail, the constituent parts of the EX7000-OEM.
