ELEC-139A Hard Contact and TTL Device Logic

Credits 2 / 2.75 Contact Hours
Prerequisite: Placement into RDNG-016 (ACSR-016). Prerequisite: ELEC-133 and ELEC-131
The foundations of logical control systems are the switches safety relays and an integrated logic family called TTL. This module will cover all aspects of switch types from toggles to heavy industrial types such as NEMA rated limit switches. Simple relay controllers will be wired and de-bugged. Fundamental industrial print reading will be covered and an introduction to binary based number systems. The TTL family of logic devices will be used to master basic logic structures and circuit reduction techniques such as Boolean algebra and Karnaugh mapping.

Course Outcomes
1. Identifying and wiring basic switch connections 2. Identifying residential and industrial switches 3. Wiring simple relay controllers from prints and de-bugging them 4. Wiring, testing and de-bugging logical controls using TTL logic devices 5. Mastering basic binary number systems 6. Reducing circuit hardware by using Boolean algebra and Karnaugh mapping techniques
