Product Overview

The Honeywell CC-TDOR11 (PN: 51308375-175) is a 16-channel Redundant Digital Output Relay IOTA for Experion PKS Series C. It uses electromechanical relays to switch high-energy field loads or provide dry-contact signals to third-party equipment.

The 12-inch vertical baseplate supports redundant DO modules (typically CC-PDOB01) for high-availability systems. G3 conformal coating ensures reliable operation in corrosive industrial environments.

Technical Data

Key Features:

• High-Current Switching: Up to 5 A per channel; can drive solenoids or motor starters directly.

• Redundant Configuration: Secondary module takes over if primary fails.

• Galvanic Isolation: Physical air gap when relay is open protects hardware.

• Configurable Safe State: Channels can Hold Last State or Shed to Safe State on communication loss.

Typical Applications

• Motor Control Centers (MCC): Start/stop signals for heavy-duty motor contactors (120/230 VAC).

• Emergency Shutdown (ESD): Hardwired interlocks for safety-critical valves and machinery.

• Third-Party Integration: Dry-contact signals to external PLCs or SCADA.

• Process Alarms: Drive high-power sirens, beacons, or horns.

FAQ

Q1: Difference between CC-TDOR01 and CC-TDOR11?
A1: CC-TDOR01 is a 6-inch non-redundant version; CC-TDOR11 is 12-inch redundant supporting two DO modules.

Q2: Can I use CC-TDOR11 with CC-PAON01 Analog Output module?
A2: No. The IOTA is specifically keyed for DO modules; installing an AO module will cause a physical mismatch.

Q3: Do the relays require external power?
A3: Relay coils are powered via Series C I/O Link; switched AC/DC voltage (“wetting voltage”) is supplied via terminal blocks.

Q4: Are the relays replaceable?
A4: Relays are usually soldered; a failed relay requires replacing the IOTA board or specific channel if repair is available.
