SV9
 New
accessory for easy connecting of detectors and digital inputs/outputs.
SV9 is a successor of SV8 terminal board. The new accessory contains
replacable screw contacts for even easier acces to the wiring. The
onboard LED diodes indicate the state of the digital inputs and outputs.
This feature will help with troubleshooting of the connections.
The board is strongly recommneded for connecting the General Purpose
Fraction Collector (FC GP) control module.
The connection between the Clarity Chromatography Station’s
A/D converters and the instruments is usually made using the standard
INT7 compatible cable supplied with the station. The leads in the
cable are soldered to a D-SUB 37 pin (CANNON) connector. Any change
in the wiring then requires skills with soldering.
The SV9 Terminal board with easily accessible screw contacts and LED
status indication is very suitable for users who will need to change
the configuration of their instrument connections often or plan to
use the additional digital inputs and outputs for instrument control,
for example to use the digital output lines for controlling gradient,
fraction collector, detector program start, detector autozero or valves
switching.
This boxed printed board has the pins of the INT7 compatible connector
conveniently available as detachable screw contacts.
For convenient access, the box is connected to the A/D Board with
a 60 cm flat cable. The state of logical inputs and outputs is indicated
by corresponding Light Emitting Diodes (LED). The state of logical
inputs IN1 to IN4 is indicated inside the box using green LEDs and
digital outputs OUT1 to OUT8 are indicated using red LEDs.
Some interferences induced in the unshielded flat cable cannot be
excluded, however none were observed during thorough testing. |
