Product Overview

The Honeywell 8C-TAID61, identified by engineering part number 51307069-175, is a high-performance Digital Input (DI) interface card specifically engineered for the Series 8 I/O hardware family within the Experion PKS environment. This module functions as a critical data acquisition point, capturing discrete binary signals from field-side equipment—such as limit switches, valve positioners, and motor starter contacts—and relaying them to the central control processor. Designed with the distinctive Series 8 vertical form factor, the 8C-TAID61 optimizes cabinet space and thermal airflow. It provides high-speed signal processing and robust electrical isolation, ensuring that transient noise from the plant floor does not compromise the integrity of the Distributed Control System (DCS) logic.

Industrial Deployment and Scenario-Specific Utility

The 8C-TAID61 is primarily utilized in sectors where high-speed discrete state monitoring is essential for safety and operational logic. In Petrochemical Refineries, it is often tasked with monitoring the open/closed feedback loops for safety isolation valves, where millisecond accuracy is required for Sequence of Events (SOE) recording. Within Automated Manufacturing Plants, the board processes signals from high-frequency proximity sensors on conveyor systems, ensuring synchronized movement across complex assembly lines. Furthermore, it is a staple in Thermal Power Generation facilities for tracking motor starter auxiliary contacts and emergency stop circuits. Its ruggedized design and wide operating temperature range allow it to be deployed in remote instrument buildings or locally mounted cabinets where environmental conditions fluctuate. The plug-and-play architecture of the Series 8 platform allows for rapid hot-swapping of the 8C-TAID61, significantly reducing the Mean Time to Repair (MTTR) during maintenance cycles.
