Honeywell 2MLR-DBSH – Expansion Driver Module | TDC 3000 DCS Platform
Engineering Background
The Honeywell TDC 3000 (Total Distributed Control) platform has been the backbone of process automation in refining, petrochemical, and power generation facilities for decades. The 2MLR-DBSH is a dedicated Expansion Driver Module designed to extend the I/O and communication capacity of TDC 3000 control nodes, enabling seamless integration of additional field devices without architectural redesign.
Product Positioning
Targeted at maintenance engineers and procurement specialists managing legacy TDC 3000 installations, the 2MLR-DBSH provides a direct, drop-in replacement path that preserves existing wiring infrastructure and control logic. Sourced through Konmask’s verified industrial supply chain, each unit undergoes functional inspection prior to dispatch.

- Water treatment and utility automation systems
Engineering Advantages
- Drop-in compatibility: Designed for direct replacement in existing TDC 3000 cabinets — no rewiring or firmware changes required.
- Expanded I/O capacity: Enables additional field device connections without modifying the control node architecture.
- Proven reliability: Honeywell TDC 3000 modules are engineered for 24/7 continuous operation in harsh industrial environments.
- Long lifecycle support: Critical for facilities maintaining TDC 3000 systems beyond OEM active production cycles.
- Reduced downtime risk: In-stock availability at Konmask minimizes lead time for emergency replacements.
System Architecture & Signal Flow
The 2MLR-DBSH interfaces directly with the TDC 3000 backplane bus, receiving power and communication signals from the host control node. It extends the driver capacity of the local control network (LCN) or basic controller (BC) segment, routing expanded I/O signals to field termination assemblies (FTAs) via standard Honeywell cabling. The module operates transparently within the TDC 3000 configuration environment — no additional software licensing is required for integration.

Technical FAQ
Q: Is the 2MLR-DBSH compatible with TPS (TotalPlant Solution) as well as TDC 3000?
A: Yes. The TPS platform is the evolved successor to TDC 3000 and maintains backward compatibility with 2MLR-series modules.
Q: Can this module be used as a hot-standby redundant driver?
A: The 2MLR-DBSH is a standard expansion driver; redundancy configuration depends on the host node architecture. Consult Honeywell documentation PM12-200 for redundancy options.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Contact Konmask for real-time availability.
Q: Do you provide a certificate of conformance?
A: Yes, a functional test report and certificate of conformance are available upon request for quality-critical procurement.
Q: What if the module fails within the warranty period?
A: Konmask offers a 90-day replacement warranty. Contact [email protected] with your order reference and fault description.
