The Honeywell TC-ODD321 is a 24 VDC digital output module for the Experion chassis I/O platform. It features 32 non-isolated output channels configured into two groups with 16 points per common ground. Designed to drive field devices such as solenoids, relays, and indicators, the device processes digital control signals from Experion C200/C200E controllers with fast, solid-state response.
