• Isolation Voltage – Channel to Channel: 100% tested at 1500 VDC for 1 second
• Isolation Voltage – User to System: 100% tested at 1500 VDC for 1 second
• Connection Terminal Blocks: TC-TBCH, 36-position terminal block

Input Delay Time Settings

• Off-to-on delay offers programmable filter options of 0 ms, 1 ms, or 2 ms.
• On-to-off delay offers programmable filter options of 0 ms, 1 ms, 2 ms, 9 ms, or 18 ms.
• Hardware delay stays at 1 ms maximum plus filter time for both directions.
• Shorter filter times suit high-speed registration and position sensing.
• Longer filter times suppress contact bounce and electrical noise on long cable runs.

Installation Guide

• Mount the TC-IDD321 on a compatible Honeywell backplane or chassis.
• Use the TC-TBCH 36-position terminal block for all field wiring connections.
• Group sixteen input points per common terminal to match the module layout.
• Confirm the on-state voltage range of 10–31.2 VDC at 60°C before powering field devices.
• Keep the off-state voltage below 5 V to prevent unintended channel activation.
• Set the programmable filter times to match your control loop response needs.
• Verify isolation integrity with a 1500 VDC test after installation if required.
