System Compatibility
The WOODWARD 5437-843 chassis is designed for use within the Micronet control system platform. It is compatible with the following module families when installed in the correct slot configuration:
- Micronet analog input/output modules
- Micronet digital I/O modules
- Micronet communication interface modules (serial, Ethernet variants)
- Micronet power supply modules (5437-series PSU)
- Micronet processor/controller cards
Confirm slot assignments and module addressing with your system’s engineering drawings before installation.
Selection Guide
Use the following criteria to determine whether the WOODWARD 5437-843 is the correct chassis for your application:
- I/O count: Requires exactly 6 I/O module slots → 5437-843 is the correct choice
- Redundancy: If hot-standby redundancy is required, consider the 5437-845 or consult WOODWARD documentation
- Expansion: If future I/O expansion is anticipated, evaluate the 8-slot 5437-844 chassis
- Space constraints: For compact panel installations, the 4-slot 5437-842 may be preferable
- Retrofit projects: Match the chassis slot count to existing I/O module inventory to minimize reconfiguration

Replacement & Compatibility FAQ
Q: Can I use a 5437-844 (8-slot) chassis as a direct replacement for the 5437-843 (6-slot)?
A: Physically, the 8-slot chassis is larger. It can host the same I/O modules but requires verification of panel space and backplane addressing. Not a direct drop-in without engineering review.
Q: Is the 5437-843 still in production?
A: WOODWARD periodically updates its Micronet product line. Contact Konmask to confirm current production status and available stock.
Q: Can I mix I/O modules from different Micronet generations in this chassis?
A: Cross-generation compatibility depends on firmware and backplane revision. Always consult WOODWARD’s Micronet compatibility matrix or contact our technical team.
Q: Do you provide a warranty on refurbished units?
A: Yes. Refurbished units carry a 90-day functional warranty. Extended warranty options are available upon request.
Q: Can you source this part if it’s not currently in stock?
A: Yes. Konmask operates an active sourcing network for legacy and hard-to-find industrial automation components. Submit an inquiry and we will respond within 24 hours.
