Overview Manuals Chassis Layout Rack Matching Cabinet Fit Product Applications

Features:

  • Chassis format: Woodward identifies 5437-843 as a 12-slot-wide MicroNet Simplex chassis.
  • Module space: Six CPU/I/O positions normally support one CPU and five I/O modules.
  • Power bays: Two positions are reserved for separate power supplies.
The chassis establishes the module arrangement; the installed CPU, I/O cards and application determine the control functions.

Woodward identifies 5437-844 as a larger 18-slot-wide chassis with twelve CPU/I/O positions, so the two chassis numbers represent different layouts.

A rack-label photo and a list of fitted modules distinguish a chassis-only request from a populated assembly.

Apter Power can quote the Woodward 5437-843 chassis and provide its MicroNet installation reference.
Woodward 5437-843 MicroNet 12-Slot Chassis with 6 I/O Slots Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • CPU position: One of the six CPU/I/O positions normally houses the CPU module.
  • I/O positions: The remaining five positions accommodate the application’s I/O modules.
  • Power-supply bays: Two separate bays each occupy three chassis-width units within the 12-wide frame.
  • Exact frame: 5437-843 uses a 12-width-unit chassis with six CPU/I/O positions.
  • Larger variant: Woodward 5437-844 uses an 18-width-unit frame with twelve CPU/I/O positions; it is not the same layout.
  • Replacement scope: The rack label and occupied-position record distinguish the chassis from the modules fitted in it.
  • Airflow: Fit modules or the specified blanking plates in open positions so forced-air cooling follows the intended path.
  • Mounting: Woodward recommends bulkhead mounting for the MicroNet Simplex chassis rather than rack mounting.
  • Clearance: Keep 8 cm of free space above and below the chassis for ventilation.
  • Grounding: Connect protective earth at the chassis ground point below the left side.
  • Installed MicroNet systems: Use the exact 5437-843 chassis reference when the existing cabinet documentation specifies it.
  • Service spare: Replace a 12-width-unit Simplex chassis with six CPU/I/O positions without implying that fitted modules are included.
  • Separately specified assemblies: Quote the chassis, CPU, I/O cards and power supplies as distinct items when the project scope separates them.
Description
In a MicroNet Simplex control cabinet, 5437-843 is Woodward’s 12-slot-wide chassis with six CPU/I/O positions. The part identifies the chassis assembly, not a populated controller.

Woodward’s 5437-843 layout normally accommodates one CPU and five I/O modules. Separate power-supply positions and the chassis airflow arrangement shape how the assembly fits an existing cabinet; the fitted modules determine the actual control functions.

For a 5437-843 replacement, Apter Power can quote the chassis separately from requested modules and provide its installation reference. The existing rack label and populated-slot list help us match the supply scope without assuming that another MicroNet chassis is interchangeable.

Technical notes
Woodward 5437-843 has six CPU/I/O positions within a 12-width-unit MicroNet Simplex chassis. Two additional bays take the power supplies, with each supply occupying three width units. This distinction matters when checking a cabinet opening or counting installed cards: the chassis number does not specify the CPU, I/O modules, or supplies fitted at the site.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What should be checked before installing a replacement Woodward 5437-843?
Compare the 12-width-unit frame, six CPU/I/O positions and two power-supply bays with the installed cabinet layout.
Does a Woodward 5437-843 quote include the installed control and I/O cards?
Woodward identifies this part as a chassis. A quotation should state separately whether any fitted control or I/O modules are included.
Can the larger MicroNet chassis replace 5437-843 without cabinet changes?
No. Woodward lists 5437-844 as an 18-width-unit frame with twelve CPU/I/O positions, so it is not the same chassis layout.
Are blanking plates included with a 5437-843 chassis?
Woodward specifies 3799-301 blanking plates for unused positions, but the chassis part number alone does not establish whether they are included. Request them separately if needed.
What is useful in a Woodward 5437-843 spare-parts request?
A clear chassis-label photo, module population and rack configuration help match the exact assembly and quoted scope.
Can Apter Power provide documentation for Woodward 5437-843 before quotation?
Apter Power can provide the applicable Woodward MicroNet reference and review the requested chassis configuration before quotation.
