Expert Purchasing Guide & FAQ

• How do I define the input range for each channel on the MLF-AD04C?
• Input ranges are software-configurable. You must select the specific voltage or current mode in the PLC parameters before wiring.
• Why is 14-bit resolution significant for my operation?
• It allows the module to detect increments as small as 0.625mV (on 10V range), ensuring superior precision in chemical or pharmaceutical dosing.
• Does the MLF-AD04C provide channel-to-channel isolation?
• The module features isolation between the field inputs and the PLC power, but the 4 channels share a common ground potential.
• How can I simplify scaling in my PLC code with this module?
• Utilize the "Precise Value" output format. It scales the raw data directly to engineering units, saving significant programming time.
• What is the best way to prevent signal noise on long cable runs?
• Always use twisted-pair shielded cables and ensure the MLF-AD04C is properly grounded via the terminal block.
