ANALOG SCREW
TERMINAL BOARD.
Introduction.
____________
This manual explains the functions and features of the
Analog Screw Terminal Board. Apart from bringing the AD1200
cards i/o lines out to easily accessible terminals the Analog
Terminal Board is designed to take several user fitted
components. Which components are fitted is determined by the
users application and by how the AD1200 card has been
configured.
The user applications covered include voltage, current and
thermocouple inputs. Whilst the ATB has features to deal with
the AD1200 card configured for 16 Single Ended, 8 Differential
Input or 16 Pseudo Differential Input channels.
Details are given on how to configure the card to deal with
all these options. Instructions of how to add the optional LEDs
and pullup resistors to the digital port lines are also included.
The Analog Screw Terminal Board
_______________________________
The Analog Screw Terminal Board is the easiest and tidiest
way to connect PC AD1200 cards to the users own rig.
The Analog Screw Terminal Board converts from the 50
IDC ribbon cable to screw terminals, making all the AD1200
pinouts easily accessible. The screw terminals can take wire up
to 2.5mm, 0.1 inch, in diameter. The 50IDC entry is a latching
connector. The four plastic mounting feet may be removed and
the terminal board used as a screw mounted panel.
The ATB has been designed to provide the following
features:-
a)
Clearly labelled, accessible port lines.
b)
Provision for necessary DI return resistors.
c)
Fuses for the +/-12 Volt lines.
d)
Provision for user fitted 4-20mA current shunts in 8 DI
mode (and exceptionally in 16 SE mode).
