Industrial Automation Control Products & Systems
            Automation control products are mechanical,
electromechanical, and solid-state devices that monitor, control, or
actuate power utilization apparatus, including motor regulation. 
Automation
and control products and solutions cover the breadth of the
manufacturing, transportation, and building sectors—from logic devices
to complex process systems, including:
    - Communications devices, networks, and software for industrial automation control products and systems
 
    - Machine
    logic control, systems, hardware, and associated software used in
    monitoring, and control of industrial processes, including programmable
    logic controllers, process controllers, and distributed control systems
 
    - Motor
    controls and accessories that start, stop, protect, accelerate,
    decelerate, reverse, and control the speed of motors, including AC and
    DC brakes and clutches, adjustable speed and variable frequency drives,
    and motor controllers
 
    - Man/machine interface devices that require
    human intervention to control and communicate the status of machines or
    manufacturing processes
 
    - Systems integration services to plan, develop, implement, and manage integrated manufacturing and process control systems
 
    - System
    elements that include analog-digital convertors and transducers,
    autotransformers and reactors, digital display devices,
    electromechanical and solid-state contactors, indicating lights, medium
    voltage controllers, motion control, overload devices, photoelectric
    relays, register and synchronizing controls, rheostats and resistors,
    solenoids, starters, terminal blocks, and timers
 
NEMA
Industrial Systems Standards are used throughout North America and the
world to specify industrial automation and control products and to aid
in the selection and application of these products. NEMA expands the
reach of automation in manufacturing, which saves labor, electricity,
and material costs, and improves quality, accuracy, and precision.
