Honeywell CC-SDOR01 51308380-175 Digital Output Relay Extension Module

CC-SDOR01 Honeywell Product Overview:

The Honeywell CC-SDOR01 (part number 51308380-175) is a digital output relay extension module made for Honeywell’s Experion PKS Series C I/O systems. This I/O Terminal Adapter (IOTA) is not redundant; it adds more relay outputs with isolated dry contacts to base digital output modules. This makes it safe and dependable to connect to field devices. People often call it the CC-SDOR01. It connects control logic to actuators and signals in tough settings, which is very important for industrial automation.

The CC-SDOR01 is built to last, with electromechanical relays that can handle heavy-duty switching and loads up to 5A at 250 VAC resistive. It has jumper-selectable Form A or Form B connections, open-wire diagnostics, and a conformal covering that protects it from moisture, dust, and chemicals. This makes it perfect for the marine, oil and gas, and manufacturing industries. The module can be mounted directly on DIN rails or I/O racks. It has screw terminals that make it easy to wire up to 32 channels in extended configurations.​

In real-world industrial settings, the CC-SDOR01 controls solenoids, motor starters, valves, and alarm horns in DCS frameworks. This makes it possible to automate processes like batch mixing, pump sequencing, and emergency shutdowns with great accuracy. Because it is electrically isolated (1500 VAC RMS), it avoids noise coupling and ground loops, which makes power plants and petrochemical plants more reliable. Operators like that it can work in a wide variety of temperatures (-40°C to 85°C) and that it has hazardous area certifications (Class I Div 2), which means it may be used in explosive environments without any extra barriers.

Technical Specifications:

Key Features

1. 32 Isolated Relay Channels: Delivers high-density discrete switching with complete channel-to-channel and coil-to-contact isolation rated at 2,500 VAC RMS.
2. Field-Configurable Contact Form: Individual channel jumper links allow seamless selection between Form-A (NO – Normally Open) and Form-B (NC – Normally Closed) contact states.
3. Integrated Counter-EMF Snubbing: On-board suppression circuitry dissipates transient inductive energy generated when de-energizing high-inductance coils, protecting internal contacts.
4. Socketed Subminiature Relays: Easy field maintenance without desoldering or unmounting terminal blocks, minimizing DCS downtime during turnaround windows.
5. Marine & Harsh-Environment Conformal Coating: Factory-applied dielectric coating prevents salt-mist dendrite growth, sulfur corrosion, and condensation-related tracking.

Frequently Asked Questions

What is the primary purpose of the Honeywell CC-SDOR01 module?

The CC-SDOR01 is a 32-channel digital output relay extension board that provides galvanic isolation and voltage level translation. It allows 24 VDC solid-state DCS outputs to switch high-voltage or high-current AC/DC field loads (up to 250 VAC / 3 A) without damaging controller electronics.

Can each channel be configured individually for Normally Open (NO) or Normally Closed (NC)?

Yes. Each of the 32 channels features its own dedicated on-board hardware jumper pin group, allowing you to configure channels independently as Form-A (NO) or Form-B (NC) contacts.

Is the CC-SDOR01 module hot-swappable?

While the Series C IOM modules are hot-swappable in live IOTA backplanes, maintenance on the CC-SDOR01 relay board involves high field voltages (up to 250 VAC). It is strongly recommended to isolate external field power circuits before servicing or replacing socketed relays to avoid electrical shock hazards.

What are the maximum voltage and current limits supported by the relays?

The dry contacts support switching up to 250 VAC RMS or 125 VDC, with a maximum steady-state continuous resistive current rating of 3.0 Amperes per channel.

Does the board have built-in status diagnostics?

Yes. Every channel is equipped with an on-board status LED indicator that illuminates amber/yellow when the corresponding digital output drive circuit is energized.
