ELC226 - Electro-Mechanical Devices I
Credit Hours: 4
Course Description
This course introduces basic electro-mechanical devices found in typical industrial systems. Industrial electrical symbols, ladder diagrams, contactors, motor starters, solenoids, transformers, relays and motors: DC, single-phase and three-phase will be covered.
Course Prerequisites
ELC134 or HVA205
Student Learning Outcomes
Upon completion of this course, students will be able to:
- Identify the differences between pictorial drawings, wiring diagrams, schematic diagrams, line diagrams, block diagrams, and flow charts
- Draw a circuit diagram that illustrates the five basic components of an electrical circuit using the appropriate schematic symbols
- Compare and contrast the characteristics of contactors, motor starters, and solenoids
Identify and operate common tools and test instruments used for troubleshooting in the electronics industry including: continuity tester, receptacle tester, volt meter, amp meter, ohm meter, digital and analog display, diode tester, oscilloscope, logic probe, and megohmmeter
- Apply basic rules for lockout/tagout to properly remove power from an electromechanical system
- Create ladder diagrams using standard line number references, numerical cross-references, wire reference numbers, and manufacturer’s terminal numbers
- Classify the components in an electrical circuit as being a part of the signal, decision, or action section of a control circuit
- Manipulate AND, OR, NOT, NAND and NOR logic, along with memory control circuits, to construct a relay ladder diagram that correctly represents the circuit operation
- Draw and interpret schematic diagrams for circuits with AC/DC and manual contactors and starters
- Identify differences between types of electrical switches such as SPST, SPDT, and DPST
- Describe the characteristics of common mechanical and automatic input devices, including temperature, flow, and level switches
- Compare and contrast the characteristics of electromechanical and solid-state relays
- Explain the operating principles for transformers and DC and AC generators and motors
- Apply the voltage and current relationships for delta- and wye-connected three-phase power
