51305776-100 TDC 3000 OEP/IKB Interface Module | Honeywell

Product Overview

The Honeywell 51305776-100 serves as a high-integrity Operator Entry Panel (OEP) and Intelligent Keyboard (IKB) interface module within the Honeywell TDC 3000 and TotalPlant Control Network (TCN) architectures. This hardware processing unit establishes a direct, real-time command bridge between operator console inputs and the host system, translating keystroke matrices into instantaneous network instructions. We stock and distribute this critical control room module in 100% brand new, original factory condition to eliminate human-machine interface (HMI) latency and guarantee immediate system responsiveness.

Technical Specifications

Engineering Advantages

• Eliminates Input Processing Lag: The dedicated onboard microprocessor decodes multi-key input sequences simultaneously, delivering sub-millisecond command execution to the host DCS during critical plant upset conditions.

• Fits Ultra-Compact Console Cavities: The low-profile 1-inch thickness solves the engineering challenge of retrofitting older, cramped operator desks. It slips easily into tight structural chassis frames right behind the console faceplates.

• Rejects Intense Desktop EMI: Advanced multi-layer shielding protects the internal logic against electromagnetic interference (EMI) and radio frequency interference (RFI) caused by adjacent CRT/LCD monitors, communication radios, and desktop computing hardware.

• Simplifies Drop-In Maintenance: Standardized alignment spacing and direct plug-and-play pinouts allow technicians to mount the module onto the console frame quickly, reducing mean time to repair (MTTR) for critical operator stations.

FAQs

• Does this product come with a warranty despite being legacy system hardware?

  Yes. Because we supply this 51305776-100 module in 100% brand new, original condition, it includes a comprehensive 12-month operational warranty that covers all components and logic performance.

• What are the proper handling procedures to avoid damaging this card during installation?

  The module contains sensitive electrostatic-discharge (ESD) components. Always ground the operator console enclosure, isolate the power feeding the keyboard bus, and wear a verified, grounded ESD wrist strap before handling the unit or connecting the ribbon cables.

• Can this module handle inputs from both the Operator Entry Panel and the Intelligent Keyboard at the same time?

  Yes. The internal hardware architecture handles dual-channel arbitration, processing signals from both the OEP and the IKB concurrently without creating key-buffer collisions or dropping user commands.
