Product Overview

The CC-TDOR11 is a Honeywell digital output relay IOTA designed for Series C / Experion PKS I/O architectures. It provides a reliable relay-based interface between a controller’s digital output commands and connected field loads. As an IOTA (Input/Output Terminal Adapter), it supports structured field wiring and termination practices while maintaining clear separation between the control layer and plant-side circuits.

This relay IOTA is typically selected where galvanic isolation and relay switching behavior are preferred over transistor outputs, such as for interposing relay logic, alarm devices, solenoid actuation circuits, or permissive/control signaling in process automation systems.

Electrical & Mechanical Characteristics

Key characteristics are summarized below for panel design, spare parts planning, and maintenance preparation.

• Output form: Relay-based digital output termination (IOTA function)

• Integration: Designed to work as part of an I/O termination assembly, supporting controller-to-field wiring organization

• Installation: Panel/cabinet mounting using standard Honeywell termination and chassis practices (depends on the installed Series C I/O build)

• Serviceability: Suited for maintenance workflows where clear field termination and modular replacement are required

Industrial Applications

• Relay-commanded outputs for solenoids, alarms, beacons, horns, and interposing circuits

• Discrete output termination in Experion PKS / Series C cabinets

• Control and permissive signaling for petrochemical, refining, chemical, and utilities plants

• Projects where relay isolation is needed to reduce electrical noise coupling or to separate field power domains
