Compatible Replacement & Equivalent Models
When the MLETN16A is unavailable or end-of-life, the following models may serve as functional replacements depending on your system configuration. Always verify compatibility with your system integrator before substitution.
- Honeywell MLETN16B – Revised revision of the same series; pin-compatible in most chassis
- Honeywell CC-TDID01 – ControlEdge 16-ch DI module; compatible in ControlEdge UOC rack
- Honeywell CC-TDOD01 – ControlEdge 16-ch DO module; use for output-only replacement
- Honeywell 51304485-150 – Legacy DI module; suitable for older Experion C200/C300 chassis
- Siemens 6ES7321-1BL00-0AA0 – Third-party 32-ch DI (requires adapter); cross-platform alternative
- ABB AI810 – Cross-brand alternative for mixed-vendor DCS environments
Note: Cross-brand replacements require engineering validation. Contact Konmask for compatibility assessment.

- Building management and HVAC control systems
System Compatibility
- DCS Platform: Honeywell Experion PKS (C200, C300, C300E controllers)
- Chassis: Experion I/O Link chassis; ControlEdge UOC rack
- Engineering Tool: Honeywell Control Builder, Experion Configuration Studio
- Firmware: Compatible with Experion R400 and above (verify with release notes)
- Network: FTE (Fault Tolerant Ethernet) and standard Ethernet backplane
Selection Guide
Use the table below to select the correct I/O module for your application:
- Need 16-ch DI only? → MLETN16A (input-configured) or CC-TDID01
- Need 16-ch DO only? → MLETN16A (output-configured) or CC-TDOD01
- Need mixed DI/DO? → MLETN16A (mixed mode) — confirm channel allocation in Control Builder
- Replacing a failed module in C200 chassis? → MLETN16A is direct replacement; no re-engineering needed
- Upgrading from legacy TDC 3000? → Consult Honeywell migration guide; MLETN16A may require I/O Link adapter
- Budget-constrained project? → Contact Konmask for refurbished/tested MLETN16A units with warranty

Replacement & Compatibility FAQ
Q: Can MLETN16A replace an older Honeywell 51304485-xxx module?
A: In most C200/C300 chassis, yes — but verify the I/O Link revision and firmware version. Contact us for a compatibility check.
Q: Is the MLETN16A compatible with Safety Manager (SM)?
A: No. Safety-rated I/O requires dedicated SIL-certified modules. The MLETN16A is for standard (non-safety) process I/O.
Q: Can I use a refurbished MLETN16A in a production environment?
A: Yes, provided it passes functional testing and firmware verification. Konmask supplies tested units with 12-month warranty.
Q: What is the lead time for new MLETN16A units?
A: In-stock units ship within 1–3 business days. For new OEM orders, lead time is typically 8–16 weeks. Contact us for current availability.
Q: Does Konmask provide installation support?
A: We provide documentation and remote technical guidance. On-site commissioning is available via our partner network.
