Product Overview

The Honeywell MU-TDID12 (Part Number: 51304441-125) is a Digital Input (DI) processor card used in Honeywell TDC 3000 and High-Performance Process Manager (HPM) systems. It is responsible for acquiring discrete status signals from field devices such as pressure switches, motor contactors, and push buttons, and transmitting these signals to the control system for monitoring, interlocking, and sequence-of-events (SOE) processing.

We supply this unit as 100% brand new and original factory equipment, ensuring high reliability, fast signal detection, and robust operation in industrial automation environments.

Technical Specifications

Engineering Advantages

High-Speed Logic Scanning
Rapid internal scanning ensures that input state changes are detected within milliseconds, supporting safety interlocks and accurate SOE timestamping.

Superior Noise Immunity
Built-in filtering circuitry mitigates EMI and RFI effects commonly found in industrial environments, reducing the risk of false triggering and signal corruption.

Optimized Form Factor
The compact 2.8 cm width allows high-density installation within standard card files, maximizing I/O capacity without increasing cabinet size.

Onboard Diagnostics
LED indicators and self-test functions provide immediate status visibility, enabling faster troubleshooting and reduced maintenance downtime.

USA Manufacturing Quality
Manufactured to strict U.S. industrial standards, ensuring durability and consistent performance under thermal stress and vibration typical of heavy industry.

FAQs

What is the difference between the -100 and the -125 revision?
The -125 revision represents a specific hardware update within the TDID12 series. While generally compatible with existing systems, compatibility with your specific TDC 3000 configuration should be verified before deployment.

Is this a brand new or refurbished digital input board?
It is 100% brand new, original equipment, supplied in factory-sealed anti-static packaging with full manufacturer markings and traceability.

Does this module require a specific Field Termination Assembly (FTA)?
Yes. The MU-TDID12 must be used with a compatible Digital Input FTA such as MC-TDID12 or MC-TDIY22, where all field wiring connections are terminated.

Can this module handle 120 VAC inputs directly?
No. It is designed for 24 VDC discrete inputs only. For AC signals, an appropriate AC-compatible FTA or interposing relay must be used to condition the input before it reaches the processor card.
