Honeywell CC-PDOB01 51405043-175 Digital Output 24V Module

Overview

The Honeywell CC-PDOB01 51405043-175 is a 32-channel Bussed Digital Output (DO) module designed for the Experion Series C I/O platform. It provides 24 V DC sourcing outputs to drive field loads such as solenoids, relays, and indicator lights, utilizing a high-density bussed power distribution architecture via the IOTA.

• On-board Diagnostics: Extensive module self-diagnostics with fault discrepancy reporting
• Conformal Coating: Yes (Standard ISA-S71.04 Class G3 environmental coating protection)
• Redundancy Support: Optional (via specific Redundant Bussed DO IOTA blocks)

Compatible Module Termination Assemblies (IOTA Models)

• CC-TDOB01: Series C Digital Output Bussed Non-Redundant 6” IOTA assembly
• CC-TDOB11: Series C Digital Output Bussed Redundant 12” IOTA assembly
• CC-GDOB11: Series C Digital Output Bussed Redundant 12” IOTA assembly (Conformally Coated)
• CC-GDOB21: Series C Digital Output Bussed Non-Redundant 6” IOTA assembly (Conformally Coated)

Key Operational Features

• Bussed Power Distribution: Features a group-bussed power design through the IOTA backplane, simplifying field wiring by routing a common 24 V DC supply across channel clusters.
• FAILOPT Configuration: Supports configurable fail-option parameters defined per channel. If the controller communication drops, channels can be independent set to HOLD LAST VALUE or SHED TO SAFE VALUE (OFF).
• Output Read-back Verification: Onboard logic continuously reads back the actual electrical state of the output switches and triggers a system alarm if a discrepancy with the commanded logic state is detected.
• Electronic Short-Circuit Safeguards: Protects internal card components against field wiring faults and shorted solenoids without requiring external inline glass fuses.

Installation Notes

• Seat the CC-PDOB01 module onto its designated 6-inch non-redundant (CC-TDOB01/GDOB21) or 12-inch redundant (CC-TDOB11/GDOB11) IOTA terminal block.
• Ensure that the aggregate current draw of all active field devices connected to the common bus does not exceed the maximum thermal and current load capacity specified for the IOTA board.
• Tighten the integrated module mounting fasteners to ensure robust mechanical grounding and electrical backplane continuity.
• Define specific channel-level FAILOPT parameters and initial state variables in the Experion Control Builder utility prior to downloading the active control strategies to the C300 controller.
