Honeywell DC-TDOD51 Digital Output IOTA

The DC-TDOD51 (part number 51307611-176) is a 32-channel digital output module and Input Output Termination Assembly (IOTA) manufactured by Honeywell for Experion and Series-C control systems. Operating on a 24 VDC bussed output, it provides high-density discrete signal switching to drive field actuators, solenoid valves, and indicator lamps. Each channel delivers up to 0.5 A of output current, ensuring reliable load control across automated process environments.

Channel Architecture and Electrical Ratings

The module features 32 independent output channels configured for 24 VDC operation. Power distribution is handled via a bussed 24 VDC output design, with each channel rated to supply a maximum current of 0.5 A. This high-density architecture minimizes cabinet footprint while supporting extensive discrete output requirements within control system chassis.

Physical Dimensions and Mounting

Engineered for compact installation in industrial control panels, the module measures 50.8 × 177.8 × 127 mm and has a net weight of 0.45 kg. Its robust construction and standardized form factor facilitate secure mounting and structured wiring termination within Series-C system enclosures.
