Product Overview

The Honeywell CC-SDOR01, identified by part number 51308380-175, is a high-density Digital Output (DO) Relay Extension Board engineered for the Experion PKS Series C architecture. This module functions as a critical expansion interface, allowing the control system to drive high-current external loads and field devices through isolated relay contacts. By bridging the gap between low-voltage control logic and high-power field actuation, the CC-SDOR01 provides a robust solution for switching inductive and resistive loads in mission-critical industrial environments.

Key Technical Characteristics

The CC-SDOR01 is distinguished by its high channel density and superior electrical isolation, ensuring that system electronics remain protected from field-side transients.

• Channel Configuration: 32 Independent Isolated Channels

• Contact Arrangements: Supports both Form A (Normally Open) and Form B (Normally Closed) configurations

• Contact Rating: 3A at 250 VAC per channel

• Switching Performance: Rapid 10ms response time for high-speed logic execution

• Isolation Voltage: 2500 VAC channel-to-system protection

• Mechanical Longevity: Rated for 100 million operations to ensure long-term duty cycles

• Environmental Range: Extreme climate tolerance from -40°C to +85°C

• Installation: Standard DIN rail mounting for rapid cabinet integration

• Humidity Tolerance: Up to 95% RH (non-condensing)

Industrial Applications

As an essential component of the Experion PKS ecosystem, the 51308380-175 is utilized across various heavy industries where reliable digital switching is paramount.

• Heavy Machinery Control: Managing the start/stop sequences of large motors, pumps, and compressors that require isolated high-voltage switching.

• Emergency Shutdown Systems (ESD): Implementing safety interlocks where physical contact separation is required for fail-safe operations.

• Process Valve Actuation: Driving solenoid valves for fluid and gas flow control in chemical and petrochemical facilities.

• Alarm and Annunciation: Controlling high-decibel sirens, beacons, and remote notification panels across expansive industrial sites.
