CHAPTER 1 - SYSTEM CONCEPT
In a system where the field wiring is required to be connected to the
rear of the system, the rack is centrally divided into front and rear
sections by a printed circuit board backplane which provides common
power and signal routeing between individual Channel Control Cards.
Channel Control Cards are fitted at the front of the rack while Interface/
Relay cards are fitted directly behind the Channel Control Cards at the
rear of the rack. The Channel Control Cards and their respective
Interface/Relay Cards are interconnected by a plug and socket
arrangement.
In a system where the field wiring is required to be connected to the
front of a system, the Channel Control Cards and Interface/Relay
Cards are mounted one above the other in a 6U rack. The backplane
printed circuit board still provides the common power and signal
routeing between the individual Channel Control Cards while short
cables at the rear of the cards connect each Channel Control Card to
their respective Interface/Relay Card.
Simple calibration and checking of the system is carried out using
push buttons on the Engineering Card fitted to each rack. More
complex configuration can be carried out using the RS232 link between
the Engineering Card and an external IBM compatible personal
computer running the engineering interface software.
Additional functions can be provided by the Engineering Card using
optional modules that plug into the Engineering Card. See the following
module operating instruction manuals:
