The Honeywell TC-ODD321 is a 24 VDC digital output module for the Experion chassis I/O platform. It features 32 non-isolated output channels configured into two groups with 16 points per common ground. Designed to drive field devices such as solenoids, relays, and indicators, the device processes digital control signals from Experion C200/C200E controllers with fast, solid-state response.

Features

32 Output Points: Arranged into 2 distinct groups with 16 points per common connection.
Linear Derating: Supports full current loads up to 50 degC with controlled linear thermal derating up to 60 degC.
Fast Switching Response: On/off signal delay times are capped at 1.0 ms maximum.
Configurable Channel States: Individual channels can be configured to hold their last state or default to ON or OFF during fault conditions or program mode.
Hot-Swappable Operation: Supports Removal and Insertion Under Power (RIUP) in non-hazardous area installations.

Applications

Driving 24 VDC industrial solenoids and actuator coils
Operating interposing control relays and contactors
Controlling field indicator lights and annunciator panels
Interface automation outputs to external subsystem logic

Installation Guidelines

Polarity Warning: The module does not feature reverse polarity protection; ensure correct wiring polarity to avoid damaging internal output circuits.
External Circuit Protection: Outputs are not internally fused. Use fused Remote Terminal Panels (RTPs) or interface modules to guard individual channels against overcurrent conditions.
Thermal Management: Maintain appropriate chassis clearance inside enclosures to ensure proper natural convection cooling across specified operating temperature limits.
Hazardous Location RIUP: Do not remove or insert modules under power if the surrounding atmosphere is classified as a hazardous location.

FAQ

What happens to the outputs if communication is lost with the controller?

Each channel can be independently configured via software to either maintain its last known state, default to ON, or default to OFF when a fault occurs.

Does the module feature built-in electrical protection against short circuits?

No, the module does not have internal short-circuit protection or fuses. Using external fused terminal blocks or fused remote termination modules is recommended.

Can this module be replaced while the chassis power is turned on?

Removal and Insertion Under Power (RIUP) is permitted in ordinary, non-hazardous areas. However, hot-swapping is strictly prohibited in hazardous locations.
