Frequently Asked Questions
Q1: What types of devices connect to the AC inputs?
A1: You can connect limit switches, push buttons, selector switches, and other 120V AC field devices.
Q2: What is the advantage of AC inputs?
A2: AC inputs are less sensitive to electrical noise and work well in industrial environments with long wire runs.
Q3: How do the trim potentiometers work?
A3: They allow manual adjustment of values that can be read by the program for calibration or operator control.
Q4: What is the maximum load per output group?
A4: Each output group common can handle up to 8A – do not exceed this rating to prevent damage.
Q5: Can I expand this controller with more I/O?
A5: Yes, you can add up to 6 expansion modules for additional input and output capabilities.
