TechCorner 29 - AutomationDirect Vs Allen Bradley PLC'sA Head To Head Comparison
Introduction:
AutomationDirect programmable controller products range from nano-sized fixed I/O Programmable Logic Controller (PLC) units to modular PLC and PAC systems with thousands of I/O. From simple machine sequencing to complex process control, you will find a quality industrial programmable controller to suit your application. This paper deals with comparing AutomationDirect Productivity3000 (PAC) and Do-more PLCs with Allen Bradley CompactLogix and ControlLogix PLCs.
