Process Control Solution – Honeywell 2MLQ-TR1C | TDC 3000 / TotalPlant Series
The Honeywell 2MLQ-TR1C is a relay-type Digital Output Module engineered for Honeywell’s TDC 3000 and TotalPlant Distributed Control System (DCS) platforms. It delivers reliable discrete output switching for final control elements in demanding continuous-process environments — from refinery control rooms to pharmaceutical batch systems.
Where This Product Is Used
- Oil & Gas Refineries – Actuating solenoid valves, motor starters, and emergency shutdown relays in SIS and BPCS loops.
- Chemical & Petrochemical Plants – Discrete output control for agitators, pumps, and interlock circuits requiring relay isolation.
- Power Generation – Switching auxiliary equipment and alarm annunciators in turbine and boiler control systems.
- Pharmaceutical Manufacturing – Batch process control for clean-room equipment and CIP/SIP valve actuation under 21 CFR Part 11 environments.
- Pulp & Paper / Water Treatment – Remote on/off control of field devices via TDC 3000 I/O racks in distributed plant architectures.

Application-Specific FAQ
Q: Is the 2MLQ-TR1C compatible with both TDC 3000 and TotalPlant DCS?
A: Yes. The 2MLQ-TR1C is designed for Honeywell’s TDC 3000 platform and is compatible with TotalPlant Series I/O racks sharing the same card form factor. Always verify slot compatibility with your rack revision.
Q: Can this module be used in a Safety Instrumented System (SIS)?
A: The 2MLQ-TR1C is a BPCS-grade output module. For SIL-rated SIS applications, consult Honeywell’s Safety Manager product line. It is widely used in non-safety discrete output loops adjacent to SIS architectures.
Q: Do you supply the matching Field Terminal Assembly (FTA)?
A: Yes — contact us with your FTA part number and we will check availability alongside the 2MLQ-TR1C.
Q: What is the lead time for this module?
A: In-stock units ship within 1–2 business days. Out-of-stock lead time is typically 2–4 weeks depending on sourcing. Contact us for current status.
Q: Can you provide a certificate of conformance or test report?
A: Yes, a basic inspection report is available on request. Third-party testing certificates can be arranged for large orders.
