Product Overview
The Honeywell TC-FOD161 is a protected 24 Vdc source digital output module. It offers 16 non-isolated channels in one group. The module fits DIN-rail mounting. It suits industrial control cabinets and legacy Honeywell systems. Each channel drives up to 500 mA. ON-state voltage ranges from 10 Vdc to 31.2 Vdc. Response is fast: 0.5 ms OFF to ON and 1.0 ms ON to OFF. The module is 100% dielectric tested at 850 Vdc for 1 s. It supports demanding switching loads with 1.5 A surge for 50 ms every 2 s. Use it for reliable discrete output control in process and factory automation.

Key Performance Highlights
- Fast switching: 0.5 ms OFF to ON and 1.0 ms ON to OFF support quick discrete control loops.
- Strong drive capability: 500 mA per channel handles relays, solenoids and lamps.
- Surge tolerance: 1.5 A for 50 ms every 2 s absorbs inrush current.
- Protected output stage: 850 Vdc dielectric test ensures user-to-system safety.
- Clear status view: 16 yellow indicators show channel state at a glance.
- Wide dc input range: 19.2 to 31.2 Vdc with 5% ac ripple tolerance.
- Rugged environment rating: 30 g shock and 5 g vibration per IEC 68-2-6.
- Compact DIN-rail form: 69 mm x 94 mm x 80 mm saves panel space.
Installation Guide
- Mount the TC-FOD161 on a standard DIN rail inside the control cabinet.
- Use 12 gauge stranded wire maximum. Keep insulation at 1.2 mm max and 90 C rated.
- Tighten terminal screws to 4 to 7 inch-pounds. Do not over-torque.
- Connect external dc power in the 19.2 to 31.2 Vdc range. Keep ripple below 5% ac.
- Confirm the Flexbus current draw stays at or below 80 mA.
- Check all 16 yellow indicators after power-up to verify channel state.
Commissioning and Maintenance
- Verify OFF-state leakage stays at or below 0.5 mA before connecting sensitive loads.
- Measure OFF-state voltage drop. Keep it at or below 0.5 Vdc.
- Watch power dissipation. It reaches 5 W at 31.2 Vdc. Provide adequate cabinet airflow.
- Keep ambient temperature between 0 and 55 C during operation.
- Inspect terminal torque and wire insulation during scheduled maintenance.
- Use the channel indicators to isolate faults quickly during troubleshooting.
Compatibility Notes
- Designed for Honeywell TC series control systems with Flexbus backplane support.
- Non-isolated channel group suits common return architectures. Plan grounding carefully.
- Works with 24 Vdc nominal loads. Confirm load current stays under 500 mA per channel.
- External dc supply must stay within 19.2 to 31.2 Vdc for stable output behavior.
- Contact our team to confirm compatibility with your existing Honeywell rack and CPU.
