Industrial Electronics

Course Descriptions

ELTRO 101                     5 credits
Basic DC-1

Fundamental theory, multi-meter usage, Ohm's Law, series and parallel circuits, voltage and current laws, series/parallel combination circuits, DC motors, generators, semi-conductors, and instrumentation. A lab section provides hands-on exercises to reinforce principles and applications to test and troubleshoot circuits. Prerequisites: MATH 093 or 096 or instructor's signature.

ELTRO 121                     5 credits
Digital Electronics

A comprehensive focus on the concepts, terminology, components and circuits that combine to form the basic digital electronic system. Includes digital number systems, gates, inverters, Boolean algebra, flip-flops, registers, timers and counters. Hands-on lab exercises include building logic gate circuits and working with 7400 series digital components. Prerequisites: ELTRO 101 or instructor's signature.

ELTRO 132                     5 credits
Intro to Computerized Controls and PLCs

Introduction to programmable logic controllers (PLCs). Includes practical lab work on industrial PLC controls. Basic ladder logic programming skills and installation methods will be introduced. Experiment with a PLC controller/simulator and mechanically controlled systems with physical inputs and outputs to reinforce concepts. Prerequisites: ELTRO 121 or instructor's signature.

ELTRO 202                     2 credits
Intro to National Electric Code (NEC)

Covers the current edition of the National Electric Code (NEC). Through classroom lecture and discussion, develops comprehension of the NEC sections and relevant industrial electronics and electricity applications.

ELTRO 210                     5 credits
Programming Software for PLCs

Course focuses on development, design and implementation of advanced programming ladder logic software and subroutines to perform industrial control processes and applications. Data organization, file management, relay instructions, comparisons, sequencers and PID control will be introduced and applied through hands-on exercises. Prerequisites: ELTRO 132.

ELTRO 220                     3 credits
Control Devices and Motor Drives

The theory of operation, calibration and troubleshooting of common control valves, actuators and motor drives, including electronic variable frequency drives (VFDs) and variable speed drives (VSDs). Prerequisite: ELTRO 210.

ELTRO 221                     5 credits
Graphic Interface Programs for PLCs

Covers elements of drag-and-drop, relaxed editor, programming and using graphics for touch-screen technology, and how to program symbolically for reusable ladder development. Includes use of software to create human machine interface (HMI/MMI) technologies, object-oriented animated graphics, and enhanced trending, alarming, derived tag creation and event detection. Prerequisite: ELTRO 210

ELTRO 223                     3 credits
Programming Software for Tag-Based PLCs

Focuses on the development, design and implementation of advanced programming ladder logic using tag-based data organization. Class focuses on the useful "tag-naming" of PLC outputs, inputs and their use in PLC logic. Tag-naming enables students to construct PLC programs that are readable and understandable by tradespersons across industry. Prerequisites: ELTRO 132.

ELTRO 230                     5 credits
Programmable Logic Controller Networks

Introduces the many networks for online communications, including Serial, ControlNet, DeviceNet, Profibus and Ethernet networks. Also use network technology to multicast input devices, share data between controllers and control remote I/O. Prerequisite: ELTRO 220.

ELTRO 231                     5 credits
Troubleshooting Electronic PLC Control Systems

Learn procedures for isolating and safely correcting problems in an industrial electricity/electronics system. Includes editing, uploading, downloading, saving and restoring PLC programs, and interpreting basic ladder logic instructions. Hands-on practice uses actual electronic controls and PLC system workstations. Prerequisites: ELTRO 210.

ELTRO 240                     5 credits
Industrial Hydraulics and Pneumatics

Introduction to hydraulic and pneumatic systems, fluids, pumps, sensors, control devices, control valves, hydraulic cylinders, and receiver controllers. Includes system energy requirements, hydraulic and pneumatic logic, and the requirements and examples for interfacing into electronic Programmable Logic Controllers (PLC) automation controllers.

ELTRO 196/296           1-5 credits
Cooperative Work Experience
