MKS Measurex CDN494 Series: Comprehensive Module Range and Technical Overview

The MKS Measurex CDN494 series PCB assemblies are deployed across heavy industrial process control environments including paper mills, film manufacturing lines, chemical processing plants, and continuous web inspection systems. The C3352 board — cross-referenced as CDN494 W/ TYPE AB, part numbers 15049401, 118100053715, MC-31106A, 510000422, and 700009786 — represents a core signal processing and interface assembly within the Measurex scanner platform. These boards are embedded in systems that have operational lifespans exceeding 20 years, making reliable spare parts sourcing a critical operational requirement for plant maintenance teams globally.

The Evolution of CDN494 Architecture

The Measurex CDN494 board family was developed as part of Honeywell's acquisition and integration of Measurex Corporation's scanner control platform. Early revisions (TYPE AA) focused on analog signal conditioning for basis weight and moisture sensors. TYPE AB introduced enhanced noise immunity and revised backplane communication logic compatible with the Measurex 4000 and 8000 series scanner frames. Subsequent hardware revisions addressed EMI compliance requirements and expanded sensor head compatibility. As Honeywell consolidated the Measurex product line under its Performance Materials & Technologies division, the CDN494 platform entered a maintenance-only lifecycle phase. No direct drop-in replacement has been released; field engineers must source original boards or validated refurbished units to maintain scanner uptime. Compatibility spans the following Measurex controller generations: MX4000, MX8000, and select MX2000 configurations with appropriate backplane adapters.

Quality Control for the CDN494 Range

Each CDN494 / C3352 board processed by DriveKNMS undergoes a structured inspection and functional verification protocol specific to the Measurex scanner platform architecture. The procedure includes: visual inspection of backplane edge connector contacts for oxidation and mechanical wear; ESR measurement of electrolytic capacitors in the analog signal path; oscilloscope verification of clock signal integrity on the digital bus interface; functional power-on test with simulated backplane load; and comparison of EEPROM configuration data against known-good reference images for TYPE AB and TYPE AC revisions. Boards exhibiting marginal analog offset values are recalibrated using Measurex-specified trim procedures before release. All tested units are assigned a DriveKNMS inspection certificate with test date, technician ID, and measured parameters on file.
