ELEC 254 - Intermediate Allen Bradley Programmable Logic Controllers

2 Credit: (1 lecture, 1 lab, 0 clinical) 2 Contact Hours: [ELEC 253 ]

This course will emphasize programmable logic controllers (PLC), their use, selection, setup, and servicing. This course is designed to give the industrial technician/electrician an intermediate understanding of the Allen Bradley PLC using RSLogix software, its logic functions, its installation, and troubleshooting.
OFFERED: fall and spring semesters
