MSX-E1701: Digital I/O
Appendix
transfer data without electrical continuity, to eliminate high-
potential differences and transients.
Output voltage
The nominal voltage output reading when shaft is rotated to full
range, expressed in volts DC /Vo DC).
Parameter
The parameters of a control comprise all for the control process
required numeric values, e.g. for limit values and technological
number.
Reference voltage
Reference voltages are stable voltages that are used as reference
unit. From them voltages can be derived that are required for
example in current supplies and in other electronic circuitries.
Resolution
The smallest significant number to which a measurement can be
determined. For example a converter with 12-bit resolution can
resolve 1 part in 4096.
Sensor
A device that responds to physical stimuli (heat, light, sound,
pressure, motion, etc.) and produces a corresponding electrical
output.
Throughput rate
The maximum repetitive rate at which data conversion system can
operate with a specified accuracy. It is determined by summing
the various times required for each part of the system and then by
taking the inverse of this time.
Trigger Internal
trigger:
A software generated event that starts an operation.
External trigger:
An analog or digital hardware event from an external source that
starts an operation.
Digital trigger:
An event that occurs at a user-selected point on a digital input
signal. The polarity and sensitivity of the digital trigger can often
be programmed.
