Product Description

Description

The Honeywell CC-TDOR11 (Part Number 51308378-175 Rev A1) is a 12-inch Redundant Digital Output Relay Input Output Termination Assembly (IOTA) designed for the Honeywell Experion Series C process automation system. Functioning as an integral field termination platform for the C300 Controller architecture, it provides the physical termination point, signal routing, and power distribution for 32-channel digital output relay operations. By combining field wiring connections and electronic module mounting into a single chassis-less footprint, the CC-TDOR11 eliminates the requirement for separate card cages or rack chassis in cabinet layouts.

Engineered with conformally coated printed wiring boards (indicated by the CC prefix), the Honeywell CC-TDOR11 offers high environmental protection against harsh, corrosive, or industrial atmosphere contaminants. The IOTA operates with the CC-PDOB01 digital output module to drive up to 32 isolated dry contacts (Form A SPST/NO or Form B SPST/NC, jumper selectable per channel). Designed for high-reliability process control applications, it supports dual-channel redundant configurations to ensure uninterrupted switching execution across critical final control elements.

Features

Redundant Architecture: Serves as a 12-inch redundant IOTA assembly enabling high-availability digital output operations paired with Series C control hardware.
Chassis-less Series C Form Factor: Direct mount design combines field termination and module interface in one compact layout, eliminating extra rack chassis hardware.
32-Channel Relay Interface: Designed to support 32 field-isolated digital outputs using Form A (Normally Open) or Form B (Normally Closed) dry contacts selectable via channel jumpers.
Conformal Coating Protection: Features factory conformally coated circuit assemblies for enhanced durability in harsh chemical and industrial environments.
Wide Load Voltage & Switching Capability: Accommodates switching control for loads up to 250 VAC (RMS) or 125 VDC across both resistive and inductive industrial field loops.
High Galvanic Isolation: Provides 1500 VAC RMS or ±1500 VDC electrical isolation between field circuitry and system internal logic.

Applications

Process Final Control Element Switching: Interfacing C300 control systems to interposing relays, solenoid valves, motor starters, and field annunciator panels.
Emergency Shutdown (ESD) & Safety Interlocks: Executing discrete power contact separation and fail-safe relay switching in critical safety shutdown loops.
High-Voltage Load Isolation: Galvanically separating sensitive 24 VDC control system electronics from high-voltage AC/DC field equipment.
Industrial Plant Automation: Deployed across continuous process plants including chemical refining, power generation, oil and gas processing, and industrial utilities.

Installation Guidelines

Pre-Installation Inspection: Verify the part number (51308378-175 Rev A1) and check the assembly for physical damage before mounting into the cabinet assembly.
Mounting: Secure the 12-inch CC-TDOR11 IOTA onto the standard Series C carrier channel within the control cabinet. Ensure adequate clearance for module plug-in and field wiring routing.
Contact Form Selection: Configure channel jumpers on the IOTA prior to field connection to select either Form A (Normally Open) or Form B (Normally Closed) operation for each individual output channel.
Field Wiring Connection: Connect field switching wires to designated IOTA terminals. Ensure field supply voltages do not exceed 250 VAC RMS or 125 VDC.
Grounding & Isolation Verification: Confirm field wiring maintains galvanic isolation requirements (up to 1500 VAC RMS / ±1500 VDC) between external power sources and system common.
Module Insertion: Carefully seat the digital output module onto the IOTA connector header until fully latched.

Commissioning & Replacement Recommendations

Parameter & Configuration Backup: Save control strategy configurations in Experion PKS prior to replacing or upgrading IOTA hardware.
Low-Level Contact Switching Note: If a relay contact channel has previously switched high-voltage or high-current loads, do not reuse that specific channel for low-level switching (5 VDC / 10 mA) due to potential contact surface alterations.
Redundant Switchover Testing: Verify smooth redundant switchover capability across both module slots under nominal 24 VDC power conditions prior to placing output channels online.
Maintenance Checks: Periodically perform operational contact tests to track mechanical contact life cycles under high inductive load operations.

The Honeywell CC-TDOR11 51308378-175 Rev A1 is a 12-inch redundant Input Output Termination Assembly (IOTA) for Experion Series C control systems. It provides physical field wiring terminations and mounting interfaces for 32 isolated digital output relay channels, routing signal control from the C300 Controller to external devices.

How are contact output types configured on the Honeywell CC-TDOR11 module?

Each of the 32 channels on the Honeywell CC-TDOR11 IOTA can be individually configured as Form A (SPST Normally Open) or Form B (SPST Normally Closed) dry contacts using physical jumpers located directly on the termination assembly.

What load switching ratings are supported by the Honeywell CC-TDOR11 digital output relay assembly?

The Honeywell CC-TDOR11 assembly supports maximum load voltages up to 250 VAC RMS and 125 VDC. It handles steady-state resistive currents up to 3 A at 250 VAC / 125 VAC / 30 VDC, and inductive loads up to 2 A at 250 VAC.

Can low-voltage low-current loads be switched on the Honeywell CC-TDOR11 relay channels?

The Honeywell CC-TDOR11 supports minimum load conditions down to 5 VDC and 10 mA, provided the output contact channel has not been previously used for high-current or high-voltage load switching.

What is the difference between CC-TDOR11 and CU-TDOR11 model numbers?

The CC prefix in CC-TDOR11 indicates that the printed circuit boards are conformally coated for corrosion and environmental protection, whereas the CU prefix denotes an uncoated assembly.
