Installation Guidance

• Mount the Honeywell TC-FOD321 on a standard DIN rail in a dry, clean enclosure.
• Ensure external DC power stays within 10–31.2 Vdc with less than 5% ripple.
• Use 12 AWG stranded copper wires with 75 °C insulation for field connections.
• Follow group wiring rules: channels 0–15 share a common return; channels 16–31 share another.
• Keep field wiring separate from system power to maintain the 2121 Vdc isolation.
