Honeywell 51304467-100 Circuit Board

The 51304467-100 circuit board supports signal processing inside Honeywell TDC 3000 control systems. This board links field wiring to the backplane through a compact single-slot layout. Plant engineers value its steady performance across continuous production cycles.

Component Count and Circuit Layout

The 51304467-100 carries 40 discrete components on a multilayer circuit assembly. Among these parts, 12 filter capacitors suppress electrical noise from adjacent equipment. Additionally, 8 precision resistors maintain stable signal levels across the board. The layout keeps trace lengths short for consistent electrical behavior.

Physical Dimensions and Weight

This board measures 12.5 inches in length and 7.5 inches in width. Board thickness reaches 1.2 inches, while the unit weighs approximately 2.0 pounds. These dimensions match standard TDC 3000 card file slots exactly. Consequently, technicians swap boards without rack modifications during shutdowns.

Interface and Isolation Parameters

Two 50-pin edge connectors handle backplane communication and field termination. The 51304467-100 delivers 250 VDC isolation between signal circuits and logic ground. Signal conversion achieves 12-bit resolution across the full operating range. Therefore, the board preserves data integrity in electrically noisy plant environments.

Power Requirements and Energy Storage

The board draws 0.70 A from the +5 VDC backplane supply rail. An onboard lithium cell protects configuration data during power interruptions. This energy storage element retains parameter settings for roughly 90 days. Meanwhile, total consumption stays below 3.8 watts under normal operation.
