Honeywell 8C-TDODA1 51307149-175 Digital Output Module

High-Density Discrete Actuation for Experion PKS

The Honeywell 8C-TDODA1 51307149-175 functions as a high-density digital output module within the Experion PKS distributed control system. This module provides 32 discrete output channels, each delivering 24 V DC at 0.5 A for driving field actuators. Its robust housing measures 130 mm in height, 45 mm in width, and 120 mm in depth, fitting standard Series C termination assemblies. The total weight reaches approximately 0.5 kg, offering durability without adding unnecessary bulk to control cabinets.

Each output channel includes short-circuit protection and thermal shutdown for reliable performance. The following table details the complete technical specifications for this digital output solution:

Channel Architecture and Load Driving Capability

The 32 output channels operate independently, allowing flexible control of multiple field devices. Each channel handles continuous loads up to 0.5 A for driving relays and indicator lamps. The total module capacity of 16 A supports simultaneous operation of all channels. Engineers can therefore connect diverse loads without additional interposing relays.

Protection Mechanisms and Diagnostic Features

Electronic short-circuit protection immediately disables affected channels during fault conditions. Thermal shutdown safeguards the module during sustained high-load operation. LED indicators provide real-time status for each individual output channel. Maintenance teams can therefore identify faulty channels quickly during inspections.

System Integration and Experion PKS Compatibility

The 8C-TDODA1 51307149-175 interfaces with the Experion PKS controller through the Series C backplane. The module supports online replacement without interrupting the control system. This feature enables maintenance while production continues uninterrupted. System integrators can therefore maintain high system availability.
