Installation Guide

• Insert the TC-IAH161 module into a compatible Honeywell backplane slot.
• Use the TC-TBCH 36-position terminal block for all field wiring.
• Keep voltage and current input wires separated to reduce cross-talk.
• Confirm the internal 250 Ω sense resistor for current loops before wiring.
• Allow 250 milliseconds for the module to publish updated channel data.
• Test open circuit detection by removing one input lead and checking the reading.
