for the measurement and control of process
variables. Particular emphasis is placed on the
theory and appli cation of pressure, flow, level,
and tempera ture measurements. Processes
will be analyzed in terms of process dead time
and capacity to determine optimum loop turning
parameters. Selected labs using Foxboro instrumentation
will be used throughout to create real
and simulated process control systems. Prerequisite:
ELT 112.
ELT 123 Electrical Controls I
3 Credits (2 lecture 1 Lab 0 Shop)
4 Hrs/Wk (2 Hrs. Lecture 2 Hrs. Lab) *15 wks
This course is a study of the functioning of electrical
devices that are primarily used for manual
switching of circuits such as piloted single-pole
switches, Eagle three-way switches, four-way
switches, momentary relays, and latching relays.
Emphasis is placed on methods of wiring
these devices into a system following N.E.C.
procedures and interpreting blueprints and
schematics. Applications include wiring switches
to con trol lights and receptacles. Complete
switching systems are formed by wiring together
electrical equipment such as time-clocks, photoeyes,
and relays. Single-phase transformers
are used to step-up, step-down, and buck/boost
voltages. DC motors are tested and connected
for spe cifi c direction of rotation and speed. Corequisite:
ELT 111.

circuits, and oil burner controls. Particular
emphasis is on: three phase principles and calculations,
single & 3 phase motor connections,
basic motor and heating control circuits and
article 430 of the NEC. Interpreting blueprints
and schematics. Applications include: testing 3
phase motors and connecting them to basic motor
control circuits. Testing and troubleshooting
single phase motors. Connecting and troubleshooting
oil burner control circuits. Interpreting
motor control catalogs. Prerequisite: ELT 123.

transistors. These devices are analyzed by the
use of ‘r’ parameters, Load-Line analysis, and
the Ebers-Moll Model. Equivalent circuits are
derived using Thevenin’s and Nortons’s theorems.
Particular emphasis is placed on I/V characteristics,
methods of biasing, and selec tion of
replacement devices. Diode applications include
filtered rectifiers, lim iters, clampers, and Zener
voltage regula tion. Bipolar transistor applications
include current sources, transistor switch,
and the CE amplifier. Co-requisite: ELT 112.

TTL integrated circuits, and their applications in
digital systems. This includes the use of logic
gates, flip-flops, counters, shift registers, decoders,
multi plexers and demultiplexers. In addition,
we will cover IC terminology, specifications,
circuits and troubleshooting. Other logic families
besides TTL will be introduced. Electronic Workbench

are created using PLC instructions that are
categorized by function: Relay logic, timers,
counters, data-manipulation, arithmetic, datacom
parison, data-transfer, and program control.
Students set up hardware addressing on PLC
racks/modules and verify physical wiring of realworld
devices. They establish communications
between a computer and a PLC processor using
Rockwell’s RSLinx software. Ladder logic
programs are written for Allen Bradley’s PLC5
