The Honeywell CC-TDIL01 is commonly used in industrial automation environments where reliable digital input monitoring is critical. It is widely deployed in process control settings such as chemical production, power generation, oil and gas refining, and manufacturing lines, where monitoring discrete signals from sensors, switches, and other devices is essential for process safety and control. This digital input module is applicable in control systems requiring high channel density and fast, accurate input processing for fault detection, state monitoring, and control logic execution.
Industries favor the CC-TDIL01 for its ability to provide galvanic isolation and extensive self-diagnostics, which protect the system from electrical noise and faults, thus ensuring signal integrity and operational robustness.
Product Introduction and Positioning
The Honeywell CC-TDIL01 is a 24 V DC digital input module equipped with 32 input channels, designed for seamless integration within Honeywell’s Experion PKS and Series C300 Distributed Control Systems (DCS). It functions as an Input Output Termination Assembly (IOTA), facilitating direct connection and isolation of multiple field input signals.
It is positioned as a high-density digital input solution that enhances system scalability and reliability. The module supports key features such as open-wire detection, optional redundancy for increased availability, and selection between internal or external field power. This makes it an essential component in critical automation architectures where dependable discrete input monitoring drives safe operations.
Key Technical Features and Functional Benefits
The CC-TDIL01 supports 32 discrete input channels accepting standard 24 V DC signals, with an ON sense voltage between 13 V and 30 V and an OFF sense voltage up to 5 V. It employs galvanic isolation rated at 1500 VAC RMS to isolate input terminals from common reference, reducing interference impact and protecting downstream control electronics.
The module includes extensive built-in diagnostics such as open-wire detection, allowing it to identify disconnected or faulty field wiring and report invalid data signals. Configurable input indication modes support both direct and reverse logic, ensuring versatile application across varied control schemes.
Designed for rugged industrial environments, the module operates reliably across a wide temperature range (-40 to +85 °C) and fits compactly within control panel assemblies. Its internal excitation power supply eliminates the need for additional marshalling power sources, simplifying system wiring.
