9
Hexadecimal
System of representing numbers in base 16 with the digits 0... 9, and further
with the letters A, B, C, D, E and F.
Hysteresis
A sensor can get caught up at a certain point, and then "waver" at this position.
This condition results in the counter content fluctuating around a given value.
Should a reference value be within this fluctuating range, then the relevant
output would be turned on and off in rhythm with the fluctuating signal.
I/O
Input/output.
Impedance
Total effective resistance that a component or circuit has for an alternating
current at a specific frequency.
Inactive metal components
Conductive components that cannot be touched and are electrically isolated
from active metal components by insulation, but can adopt voltage in the event
of a fault.
Inductive coupling
Magnetic inductive couplings occur between two cables through which an
electrical current is flowing. The magnetic effect caused by the electrical
currents induces an interference voltage. Typical sources of interference are for
example, transformers, motors, parallel-routed network and HF signal cables.
Instance
An Instance is defined as being an Object that is actually set up in a device.
Load value
Predefined value for the counter module with which the count process begins.
Lightning protection
All measures taken to protect a system from damage due to overvoltages
caused by lightning strike.
