Hysteresis
For a system with an analog input, the output tends to maintain it's current value until the
input level changes past the point that set the current output value. The difference in response
of a system to an increasing input signal versus a decreasing input signal.
I/O
Input/Output. The reception and transmission of information between control devices. In
modern control systems, I/O has two distinct forms: switches, relays, etc., which are in either
an on or off state, or analog signals that are continuous in nature generally depicting values
for speed, temperature, flow, etc.
Inertia
The property of an object to resist changes in rotary velocity unless acted upon by an outside
force. Higher inertia objects require larger torque to accelerate and decelerate. Inertia is
dependent upon the mass and shape of the object.
Input Function
A function (i.e., Stop, Preset) that may be attached to an input line.
Input Line
The actual electrical input, a screw terminal.
Least Significant Bit
The bit in a binary number that is the least important or having the least weight.
LED
Light Emitting Diode.
mA
Milliamp.
MB
Mega-byte.
Most Significant Bit
The bit in a binary number that is the most important or that has the most weight.
ms
Millisecond.
