Product Overview

The CC-TDIL11 (CCTDIL11) is a high-availability 24 VDC Digital Input Termination Assembly (IOTA) designed for the Honeywell Experion Series C platform. As a 12-inch redundant termination base, it supports two CC-PDIL01 Digital Input modules in a redundant configuration. This design ensures continuous field signal availability in oil and gas, power generation, and chemical plants. It enables bumpless transition during module failure and allows live replacement without disrupting field wiring or plant operations.

Technical Configuration

The CC-TDIL11 is engineered for high-density installation and stable field signal management in industrial environments.

• Redundancy Architecture: Supports two I/O modules on a single termination assembly for hardware-level redundancy without external wiring complexity.
• High-Density Termination: Provides up to 32 input circuits in a compact 12-inch (304 mm) footprint, optimizing cabinet space usage.
• Integrated Field Power: Distributes field power through the IOTA, removing the need for external marshalling panels.
• Thermal Design: Uses a tilted module layout to improve airflow and maintain stable operation in high-density cabinets.

Technical Specifications

Technical FAQs

How does CC-TDIL11 improve system availability?
It supports redundant I/O modules. If one module fails, the standby module takes over immediately without process interruption.

Can this IOTA be used for SOE applications?
It supports standard digital inputs. For high-speed SOE systems, dedicated SOE modules are required.

What is the benefit of detachable terminals?
They allow pre-wiring and fast module replacement without disturbing field cable terminations.

Engineering & Installation Guide

• Install vertically to support airflow and reduce mechanical stress on terminals.
• Maintain proper spacing around modules to prevent heat accumulation in dense cabinets.
• Verify active module status indicators before performing replacement in redundant setups.
