Thermo Fisher Scientific Model 5030 i SHARP Instruction Manual 8-9
The I/O expansion board connects to the motherboard and adds the
capability to input external analog voltage signals and to output analog
currents via a connector located on the rear panel of the instrument. It
contains local power supplies, a DC/DC isolator supply, a sub-processor
and analog circuits. Eight analog voltage inputs are provided with an input
voltage range of 0V to10 VDC. Six current outputs are provided with a
normal operating range of 0 to 20 mA.
The front panel connector board interfaces between the motherboard and
the function key panel and graphics display. It serves as a central location to
tie the three connectors required for the function key panel, the graphics
display control lines, and the graphics display backlight to a single ribbon
cable extending back to the motherboard. This board also includes signal
buffers for the graphics display control signals and a high voltage power
supply for the graphics display backlight.
External I/O is driven from a generic bus that is capable of controlling the
following devices:
●
Analog output (voltage and current)
●
Analog input (voltage)
●
Digital output (TTL levels)
●
Digital input (TTL levels)
Note The instrument has spare solenoid valve drivers and I/O support for
future expansion. ▲
The instrument provides six analog voltage outputs. Each may be firmware
configured for any one of the following ranges, while maintaining a
minimum resolution of 12 bits:
●
0-100 mV
●
0-1 V
●
0-5 V
●
0-10 V
The user can calibrate each analog output zero and span point through the
firmware. At least 5% of full-scale over and under range are also supported,
but may be overridden in the firmware, if required.
