Performance and Thermal Derating

• The module supports an output range from 10 VDC to 31.2 VDC at 50°C with linear derating.
• At 60°C, the output range narrows to 10 VDC to 28 VDC for safe operation.
• Each point handles 0.5 A at 50°C with linear derating and 0.35 A at 60°C.
• The full module handles 16 A at 50°C with linear derating and 10 A at 60°C.
• Surge current reaches 1 A for 10 ms, and it repeats every 2 seconds at 60°C.
• Flash on time targets 100 µs with a 150 µs maximum for fast switching.
• Minimum on-state load current stays at 3.0 mA per output.
• Off-state leakage remains below 0.5 mA per point for clean channel separation.
• Group-to-group isolation holds 250 VAC maximum continuous voltage between groups.
• Both group-to-group and user-to-system isolation pass 2546 VDC testing for 1 second.

Installation Guide

• Mount the TC-ODD321 in a compatible Honeywell I/O rack or control panel slot.
• Use the TC-TBCH 36-position terminal block for field wiring connections.
• Add a fused IFM to protect outputs because the module has no internal fusing.
• Check wiring polarity carefully because the module lacks reverse polarity protection.
• Apply linear derating for current and voltage when panel temperature exceeds 50°C.
• Set fault states and program mode states per point before system commissioning.
• Confirm the 1.0 ms delay times fit your control loop timing requirements.
• Review power dissipation of 6.1 W when planning panel thermal management.
• Test group-to-group and user-to-system isolation before applying full field power.
