Honeywell TC-ODD321 Experion 32-Channel Digital DC Output Module
The Honeywell TC-ODD321 is a 32-channel, 24 VDC digital DC output module designed for Honeywell Experion systems, including Experion PKS and Experion LS platforms. Installed in Series A I/O chassis, it converts digital controller commands into discrete output signals to operate field actuators, solenoids, relays, and indicator lights.
Channel Grouping and Voltage Derating
The module features 32 output channels arranged into two isolated groups of 16 points per common. Operating across a nominal 24 VDC class, its allowable output voltage range spans 10 to 31.2 VDC at 50 deg C and derates to 10 to 28 VDC at 60 deg C. Output current per channel allows up to 0.5 A at 50 deg C (16 A total module limit) and 0.35 A at 60 deg C (10 A total module limit), requiring a minimum load current of 3.0 mA per point.
Electrical Performance and Protective Circuitry
Built to meet IEC 1131-2 switching standards, the module achieves fast response times with maximum OFF-to-ON and ON-to-OFF delays of 1 ms. It withstands repetitive surge currents up to 1 A for 10 ms every 2 seconds and provides group-to-group and user-to-system isolation tested at 2,546 VDC for 1 second. Output channels support configurable fault modes (hold last state, ON, or OFF), while external fused interface modules are recommended as internal output fusing and reverse polarity protection are not provided.

Frequently Asked Questions
Q: What terminal block model is used with the Honeywell TC-ODD321 output module?
A: Field connections connect to the module using the 36-position Honeywell TC-TBCH terminal block.
Q: What are the maximum current limits per point when operating at elevated temperatures?
A: At 50 deg C, each point supports up to 0.5 A (16 A max per module); at 60 deg C, output current derates to 0.35 A per point (10 A max per module).
Q: Does the TC-ODD321 include internal fused protection on its output channels?
A: No, the module does not provide internal output fusing or reverse polarity protection; using an external fused interface module is recommended.
