ELT2150 Electronic Controls

Intermediate · 1 credit · TMT - Trades, Manufacturing and Transportation

Description: Students demonstrate the fundamentals of ladder/relay logic programming and how the programmable logic controller (PLC) system operates.
Prerequisite: ELT2130: Magnetic Control Devices
Parameters: Access to a programmable logic controller, a soldering station, hand tools and related resources. Note: The student must have access to instruction from an individual with journeyman qualifications when projects are hardwired to main power supply and intended for permanent usage.
