Includes digital number systems, gates, inverters, Boolean algebra, flip-flops, registers, timers and counters. Hands-on lab exercises include experiments building logic gate circuits and working with related digital circuits. Prerequisites: ELTRO 101 or instructor’s signature.
ELTRO 132 5 credits Intro to Computerized Controls and PLCs Introduction to principles of programmable logic controllers (PLCs). Includes practical lab work on industrial PLC controls. Basic ladder logic programming skills and installation methods will be introduced. Students experiment with a real 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 2002 edition of the National Electrical Code (NEC). Through classroom lecture and class discussion, the student develops knowledge and comprehension of the code sections and relevant industrial electronics and electricity applications.
ELTRO 210 5 credits Programming Software for PLC’s Course focuses on the 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. Prerequisite: ELTRO 138.
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 PLC’s 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 powerful 32-bit 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
