Experion DC Output Module | Honeywell TC-ODD321
The Honeywell TC-ODD321 is a 32-channel digital output module designed for the Experion Process Knowledge System (PKS) C200 and C300 controller platforms. It provides 24 VDC solid-state switching for field actuators, indication lamps, relays, and solenoids in continuous industrial control applications. The module features two isolated groups of 16 output channels, reducing field wiring complexity while providing structured common connections.
Output Performance and Voltage Derating
The TC-ODD321 operates across a voltage range of 10 VDC to 31.2 VDC at ambient temperatures up to 50 deg C, with linear derating to 28 VDC at 60 deg C. Each output point supports a minimum load current of 3.0 mA, ensuring stable switching for high-impedance control loads. Maximum on-state voltage drop is restricted to 1.0 VDC at rated current, minimizing signal loss across field loops.
Circuit Protection and Wiring Interface
To handle inductive inrush loads, each output channel supports repeatable surge currents up to 1.0 A for 10 ms at 60 deg C. The module interfaces with field cabling using the dedicated TC-TBCH 36-position removable terminal block. Total thermal dissipation is rated at 6.1 W under full operating conditions.

Frequently Asked Questions
Q: What removable terminal block is required for wiring the TC-ODD321? A: The module requires the Honeywell TC-TBCH 36-position terminal block for field wiring connection and signal isolation between the two 16-point groups.
Q: How does temperature affect the output voltage range of this module? A: The module operates at full output rating up to 31.2 VDC at 50 deg C. Above 50 deg C, the maximum allowable voltage derates linearly to 28 VDC at 60 deg C.
