Description

The Honeywell CC-TDOB01 (51308371-175) is a high-density Digital Output module designed for integration within the Experion PKS control architecture. This module provides 32 output channels, engineered to manage 24V DC field devices with source-type switching. It is designed to mount onto a dedicated IOTA (Input/Output Termination Assembly), facilitating efficient field wiring and signal distribution in process automation environments.

Features

  • 32-channel digital output capacity for high-density signal control.
  • Source-type output configuration compatible with standard 24V DC field instrumentation.
  • Robust galvanic isolation rated at 1500 VAC RMS or ±1500 VDC to protect control logic from field-side transients.
  • Optimized for low leakage current (5.0 µA max) to ensure reliable off-state performance.
  • Integrated design for seamless operation with Honeywell IOTA backplanes.
