Compatible Replacement & Equivalent Models
When the 900H32-0001 is unavailable or end-of-life, the following models may serve as direct or functional replacements depending on your system configuration:
- 900H16-0001 – Honeywell HC900 16-Channel Digital Output Module (half-density alternative)
- 900H08-0001 – Honeywell HC900 8-Channel Digital Output Module (lower channel count)
- 900H32-0101 – HC900 32-Channel DO Module, relay output variant (verify output type compatibility)
- Siemens ET 200SP DQ 32×24VDC/0.5A HF – Cross-brand functional equivalent for 32-ch 24VDC DO (requires gateway/re-engineering)
- Allen-Bradley 1756-OB32 – ControlLogix 32-channel 24VDC output module (cross-brand, requires system migration)
Note: Cross-brand replacements require engineering evaluation. Always verify backplane compatibility, firmware version, and I/O addressing before substitution.

Replacement & Compatibility FAQ
Q: Is the 900H32-0001 still in production?
A: Honeywell periodically updates HC900 I/O module availability. Contact us to confirm current stock and lead time.
Q: Can I mix 900H32-0001 with older HC900 I/O modules in the same rack?
A: Yes, HC900 racks support mixed I/O module types. Slot assignment is configured in HC900 Designer software.
Q: What is the difference between 900H32-0001 and 900H32-0101?
A: The -0001 suffix indicates transistor (solid-state) outputs; -0101 indicates relay outputs. Choose based on your field device requirements.
Q: Do you offer a warranty on used/refurbished units?
A: Yes — all refurbished units carry a 90-day functional warranty. New units carry the standard Honeywell warranty.
Q: Can this module be used with Honeywell Experion PKS?
A: The 900H32-0001 is designed for the HC900 platform, not Experion PKS. For Experion, refer to the HC900-to-Experion integration guide or contact us.
