Glossary
inductive load
A load that produces a magnetic field when energized. Inductors are electrical
components that store energy and are characterized by the following equation:
E
stored
LI

inrush current
The peak instantaneous input current drawn by an electrical device when first
turned on.
keyed
Notches, slots, or other mechanical devices added to connectors so that they are
connected to their mates with the proper orientation.
ladder logic
A programming language often used in industrial-control settings to control
electromechanical devices in a relay. Programs written in this language resemble
ladders: two vertical rails with a series of horizontal rungs—each representing a
logical rule—between them. Ladder programs for Parker Vansco products are
written using Vansco Multiplexing Module Software (VMMS).
leakage current
Current that flows when the ideal current is zero.
LIM16H
A light indicator module with 16 inputs that are hardwired to telltales.
load
Any component that draws current from a module and is typically switched on
and off with outputs. Examples include bulbs, solenoids, motors, etc.
load dump
A surge in the power line caused by the disconnection of a vehicle battery from
the alternator while the battery is being charged. The peak voltage of this surge
may be as high as 120 V and may, unless precautions are taken, affect other loads
connected to the alternator.
logic ground
Ground pins for the microprocessor and logic peripherals.
logic power
Power pins for the microprocessor and logic peripherals.
