Digital Input Assembly | 51308386-175 CC-TDIL01 | Honeywell

Product Description

The CC-TDIL01 (51308386-175) is a high-density Digital Input I/O Termination Assembly (IOTA) engineered for the Honeywell Experion PKS C300 controller environment. This module provides the critical physical interface for capturing discrete signals from field-mounted devices such as limit switches, push buttons, and motor status auxiliary contacts. By utilizing the CC-TDIL01 (51308386-175), the control system receives high-integrity ON/OFF status data, which is essential for safety interlocking, sequence control, and alarm management.

Designed for high-availability industrial applications, the CC-TDIL01 (51308386-175) features 11 isolated channels to prevent ground loops and field-side electrical interference from affecting the controller backplane. This unit is supplied as 100% brand new and factory-original, featuring a rugged construction that supports continuous operation in harsh G3-rated corrosive environments.

Engineering Advantages

• High Signal Integrity: The galvanic isolation ensures that a short circuit or surge on a single field contact does not propagate to adjacent channels or the central C300 processor.

• Redundancy Management: When installed on a redundant baseplate, the CC-TDIL01 (51308386-175) enables seamless signal tracking by both primary and backup controllers.

• Industrial Durability: The -175 suffix indicates the inclusion of Honeywell’s high-grade conformal coating, protecting the PWA against moisture, dust, and corrosive airborne contaminants typical in chemical or refining zones.

FAQ

• Can the CC-TDIL01 (51308386-175) handle 120V AC digital inputs?No, this specific IOTA is designed for 24 VDC nominal signals. For 120V AC field devices, you must utilize interposing relays or a high-voltage rated digital input module.

• Is the CC-TDIL01 (51308386-175) hot-swappable?Yes, in a redundant C300 configuration, the module can be replaced while the secondary partner maintains active signal monitoring, ensuring zero downtime for the process loop.

• What is the difference between CC-TDIL01 and CC-GDIL01?The CC-TDIL01 is the functional model designation for the termination assembly, while CC-GDIL01 often refers to the internal Printed Wire Assembly (PWA). They are components of the same I/O channel subsystem.
