Honeywell TC-IDD321 Digital Input Module
The TC-IDD321 is a high-density 32-point digital input module engineered by Honeywell for industrial automation and control applications. Operating at a nominal input voltage of 24 VDC, it reliably captures and processes binary status signals from field devices, switches, and sensors. This module delivers robust performance, secure data acquisition, and reliable signal integration for complex control architectures.
Signal Configuration and Input Characteristics
The module handles up to 32 discrete input points, structured into dual groups with 16 points per common terminal to support flexible field wiring arrangements. Designed for standard 24 VDC logic environments, each channel operates efficiently with a nominal input current of 5.5 mA, ensuring clear distinction of field states while maintaining low thermal output.
Electrical Isolation and Power Performance
To protect control electronics from transient voltage spikes and ground loops, the circuitry supports high-voltage isolation rated up to 1500 VDC for 1 second. Total power dissipation is maintained at a maximum of 6.1 W, providing an energy-efficient profile for high-density cabinet installations while ensuring steady operational stability.
