IAM 4030 - PLC System Interfacing

Clock Hours: 60

Prerequisites: IAM 4020

Course Description:
This course is designed to instruct students how components that are not designed to work together can function together as a system. PLC’s are low voltage, low power devices. The input and output modules are low-power contacts. PLC’s are not designed to handle high-power loads. When components must communicate with each other but have different voltage levels, or different voltage types, or different current amounts, interface devices must be used.

Student Learning Outcomes:
Students will be able to demonstrate knowledge of:

Define the types of primary systems used to produce work in a PLC.
Describe the functions of a system interface device.
List common input devices and output components found in network control systems.
Describe common interface devices used to control high-power loads.
Define control relay and identify terms used to describe a
Compare the characteristics of electrommechanical relays and solid-state relays.
Identify common uses of contactors.
Describe the function and operation of a magnetic motor starter.
Describe the function and operation of an electric motor drive.
Identify power supply issues to consider when installing PLC’s.
List considerations for wiring PLC’s.
Identify checks required for wiring PLC’s.
Identify checks required at PLC startup.
