Honeywell CC-PDOB01 – Digital Output Bussed 24VDC

Overview

The Honeywell CC-PDOB01 is a 24V digital output module that provides reliable signal control for process equipment. It supports high energy outputs and minimizes the need for external components.

Key Features

• 32 output channels with source-type configuration
• Extensive self-diagnostics for signal integrity
• Optional redundancy support
• Fuse-less short circuit protection
• Latched, pulsed, or pulse-width modulated output per channel
• Supports user-defined safe-state (FAILOPT) behaviors
• Galvanic isolation up to 1500 VAC RMS

Output Capabilities

• Output Type: Sourcing digital outputs
• Load Voltage Range: 15–30 VDC
• Load Current Limits:
  • Per Channel: 0.5 A
  • Per 8 Channels (No Short): 4 A
  • Per 8 Channels (One Short): 3 A
  • Per 8 Channels (Two Shorts): 1.5 A
  • Per Module (Max): 6 A

Fail-Safe & Diagnostics

• FAILOPT Support: Configurable to hold last value or shed to safe value
• Short Circuit Protection: Auto shut-off without fuse damage
• Per Channel Isolation: Maintains system stability during faults

Power Architecture

• Bussed Output Design: All outputs share a common return (ground)
• Field Power Source: Internal or external 24V supply selectable
• Isolation: External field power allows galvanic isolation from system power

Redundancy & Compatibility

• IOTA Model (Non-Redundant): CC-TDOB01 (9”)
• IOTA Model (Redundant): CC-TDOB11 (12”)
• Easily integrated into Honeywell Series C control systems
