load
Any component that draws current from a module and is typically switched on
and off with outputs. Examples include bulbs, solenoids, motors, etc.
logic power
Power pins for the microprocessor and logic peripherals.
low-side output
An output that provides a switched ground voltage to an external load.
multiplexing
Transmitting multiple messages simultaneously over one channel in a local area
network.
open load
The disconnection of a load from an output, often because of a broken or worn
wire or connector pin.
overcurrent
A fault state that occurs when a load draws more current than specified for an
output, which results in the output shutting down to protect the circuitry of the
product.
overvoltage
A situation in which the voltage in a circuit rises above its upper design limit.
power control input
A digital input that is used to turn on the product. When the input is active, the
product turns on and operates in normal mode; when the input is inactive, the
product powers down and will not operate.
procurement drawing
A mechanical drawing showing the dimensions, pinouts, and implemented
configuration options for a Parker Vansco product.
proportional-integral-differential (PID) controller
A system or device controller that, through constant feedback about differences
between the desired state and the current state, adjusts inputs accordingly. An
example of such a controller is one that prevents a vehicle from traveling faster
than a specified speed, regardless of the amount of pressure on the gas pedal.
