Honeywell 51405043-175 (CC-PDOB01) Digital Output Module
https://example.com/image-cc-pdob01.jpg Product Overview The Honeywell 51405043-175, commercially designated as the CC-PDOB01, is a high-density, 32-point Digital Output (DO) module for the Experion® PKS (Process Knowledge System) and older TPS (Total Plant Solution) platforms. This module functions as a critical interface between the digital control system and the plant floor, executing commands from the controller to switch DC loads on or off. Designed for high reliability and diagnostics, the CC-PDOB01 is used to control a wide array of devices such as solenoid valves, motor starters, relays, indicator lamps, and other two-state field equipment. Its high channel density makes it ideal for applications requiring a large number of discrete outputs while optimizing control cabinet space. Key Features
- High-Density Design: Provides 32 independent digital output channels on a single module, maximizing I/O count and minimizing footprint.
- Positive/Negative Logic Configuration: Each channel can be individually configured by the user for positive (sourcing) or negative (sinking) logic operation via jumper blocks or software, offering wiring flexibility.
- Advanced Diagnostics: Features comprehensive self-diagnostics and per-channel status monitoring, including fault detection for short-circuit and open-load conditions.
- Hot Swappable: Supports online insertion and removal, allowing for maintenance or replacement without a process shutdown, thereby maximizing system availability.
- Fused Outputs: Each output channel is individually fused to protect the module and field wiring from overcurrent conditions.
- LED Status Indicators: Each channel has a dedicated LED to provide instant visual confirmation of its output state (ON/OFF) and health.

Typical Applications This digital output module is used for discrete control applications across various industries:
- Manufacturing: Controlling solenoid valves for pneumatic actuators, starting and stopping conveyors.
- Oil & Gas: Operating shutdown valves, initiating blowdown sequences, and controlling pump motors.
- Power Generation: Sequencing equipment, controlling auxiliary systems, and activating alarms.
- Water Treatment: Switching pumps on/off, controlling chemical dosing solenoid valves, and operating diverters.
Installation and Wiring
- The CC-PDOB01 module installs into a Honeywell Series A or C I/O Module Assembly (carrier).
- It requires an external, user-supplied DC power source for the output loads.
- Field wiring is connected to the module’s front-terminal unit.
- The sourcing or sinking behavior for the entire module or in groups is configured via physical jumpers on the module and/or within the Control Builder software.
