Product Description

Description

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.

Features

  • 8 Voltage Input Channels: High-density processing in a single module footprint to minimize rack space.
  • Fast Conversion Speed: Achieves a digital conversion rate of 250 microseconds per channel.
  • Electrical Protection: Photo-coupler isolation between input terminals and PLC power supply protects sensitive control logic.
  • Flexible Addressing: Supports both fixed I/O mapping (64 points) and variable mapping (16 points) to optimize backplane data exchange.
  • Secure Field Wiring: Equipped with an 18-point detachable terminal block for straightforward field maintenance.

Applications

  • Power plant auxiliary process monitoring
  • Water and wastewater flow and pressure telemetry
  • Factory automation assembly and testing lines
  • Oil and gas storage tank level monitoring

Empirical Engineering Insights

Alternative Models & Compatibility

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.

Application Pitfalls & Engineering Notes

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.

Commissioning & Wiring Tips

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.

Installation Guidelines

CRITICAL WARNING

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.

1

Ensure the MasterLogic PLC backplane is completely de-energized.

2

Align the module guides with the targeted slot on the backplane, slide the module firmly into place, and engage the locking mechanisms.

3

Wire the analog voltage inputs to the 18-point terminal block according to your system wiring diagram, ensuring correct polarity.

4

Attach the pre-wired terminal block to the front of the module and tighten the retaining screws to prevent vibration displacement.

FAQ
Can the Honeywell 2MLF-AV8A accept 4-20mA current signals?
No. The 2MLF-AV8A is designed specifically for voltage input signals. For current applications, you should use the 2MLF-AC8A module to avoid performance degradation and loop errors.
Does this module have channel-to-channel isolation?
No. The 2MLF-AV8A features photo-coupler isolation between the input terminal block and the PLC internal power supply, but there is no isolation between the 8 analog channels. External isolators should be used if ground potentials differ.
What is the maximum voltage the inputs can withstand?
The absolute maximum voltage input rate for the 2MLF-AV8A is +/-15V. Exceeding this limit will cause damage to the internal signal conditioning circuitry.
What is the physical conversion speed of the 2MLF-AV8A?
The module operates at a maximum conversion speed of 250 microseconds per channel.
