SV9 - Terminal Board
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.
