Engineered for high-density voltage acquisition within the Honeywell MasterLogic PLC platform, the Honeywell 2MLF-AV8A analog input module provides robust signal processing for industrial automation environments. This module interfaces seamlessly with field-level voltage instrumentation, converting analog signals into highly precise digital registers for the controller. With its high-speed conversions and dense channel packaging, it is ideal for systems demanding fast response times and compact panel space.

The 2MLF-AV8A is specifically designed for voltage signals. If your field loops utilize 4-20mA or 0-20mA current signals, you must use the 2MLF-AC8A current input module instead. Using inline shunt resistors on the 2MLF-AV8A to measure current signals is not recommended as it bypasses the design specifications and degrades overall loop accuracy.
Note that while there is strong photo-coupler isolation between the field terminals and the PLC backplane, there is no isolation between individual channels. If your analog inputs come from different physical locations with different ground potentials, you will experience ground loops. These loops will corrupt your measurement data and potentially damage the module. Use external signal isolators for loops with distinct ground potentials.
To minimize high-frequency noise from nearby variable frequency drives (VFDs) or motor contactors, always run analog input cables inside dedicated, grounded metal conduits separated from high-voltage AC cables. Connect the cable shield to the cabinet’s single-point ground system on the PLC end only, leaving the field end ungrounded to prevent circulating shield currents.
Disconnect all power sources to the PLC rack and field wiring terminals before installing, removing, or servicing this module. Hot-swapping the 2MLF-AV8A may cause backplane communications faults, damage internal components, or disrupt active processes.
Ensure the MasterLogic PLC backplane is completely de-energized.
Align the module guides with the targeted slot on the backplane, slide the module firmly into place, and engage the locking mechanisms.
Wire the analog voltage inputs to the 18-point terminal block according to your system wiring diagram, ensuring correct polarity.
Attach the pre-wired terminal block to the front of the module and tighten the retaining screws to prevent vibration displacement.
