Description

The Honeywell CC-SDOR01 (Part Number: 51308380-175) is a Digital Output Relay Extension Module engineered for the Experion Series C architecture. Designed to expand output contact capabilities, the module works in conjunction with the CC-PDOB01 Digital Output Input Output Module (IOM) and the corresponding CC-TDOR01 or CC-TDOR11 Relay Input Output Termination Assemblies (IOTAs). By interfacing with the 24 VDC bussed digital output driver electronics, the CC-SDOR01 allows process control systems to drive discrete high-power or low-power loads through isolated dry contact circuits.

Built with a 12-inch footprint, the Honeywell CC-SDOR01 extension assembly provides 32 isolated relay channels that accept user-configured Form-A (SPST/NO) or Form-B (SPST/NC) field contact arrangements via jumper settings. This extension board eliminates the need for external interposing relay panels, providing direct dry contact isolation between control logic and field machinery. Each output channel is equipped with socketed relays, LED status indication, and integrated counter-EMF snubbing networks to protect against inductive switching transients.

Operating within the Series C physical layout, the CC-SDOR01 features vertical mounting, a tilted thermal dissipation design, and detachable two-level field terminal blocks. The module accepts field wiring up to 12 AWG (2.5 mm sq stranded wire) and maintains galvanic isolation of 1500 VAC RMS or +/-1500 VDC between individual channels and system logic common.

Features

• 32 Isolated Relay Channels: Provides 32 dry contact outputs for high-voltage, high-current, or low-voltage switching tasks.
• Configurable Contact Operation: Supports Form-A (Normally Open) or Form-B (Normally Closed) contact configurations selected via jumpers on a per-channel basis.
• High Switching Capacity: Accommodates steady-state load currents up to 3 A at 250 VAC RMS or 30 VDC, and inrush currents up to 10 A.
• Socketed Relay Design: Individual socketed relays allow straightforward field maintenance and channel replacement.
• Built-in Transient Suppression: Integrated counter-EMF snubbing circuits (120 Ohm + 0.033 uF) protect contacts from inductive kickback.
• Galvanic Isolation: Offers 1500 VAC RMS or +/-1500 VDC isolation between channels and system logic common.
• Visual Diagnostics: Dedicated LED indicators per channel display active output status.
• Detachable Terminal Blocks: Accepts up to 12 AWG / 2.5 mm sq stranded wiring to simplify field landing and cabinet maintenance.

Applications

• Interposing Relay Isolation: Direct switching of high-voltage field devices, solenoids, and motor starters without external interposing relay racks.
• Discrete Process Control: Interfacing Experion C300 control logic with pumps, valves, fans, and annunciator panels.
• Safety System Interfacing: Providing volt-free contact signals to third-party safety shutdown systems, motor control centers (MCC), and package units.
• Mixed Voltage Load Control: Driving combinations of 24 VDC, 120 VAC, and 230 VAC field circuits from a single output assembly.

Installation Guidelines

1. Safety Pre-Installation Verification: Disconnect system logic power and field excitation power sources prior to mounting or servicing the module. Verify that load voltage and current ratings fall within specified thresholds (12 VDC to 250 VAC RMS).
2. Mounting: Secure the CC-SDOR01 extension assembly vertically onto the cabinet carrier channels. Maintain proper vertical clearance to allow heat dissipation via natural convection.
3. Interconnection Setup: Connect the extension assembly to the primary Digital Output Relay IOTA (CC-TDOR01 or CC-TDOR11) housing the CC-PDOB01 IOM using the dedicated system ribbon cabling.
4. Channel Contact Configuration: Set the channel jumper headers for each of the 32 outputs to select either Form-A (Normally Open) or Form-B (Normally Closed) dry contact functionality based on control loop requirements.
5. Field Wiring Termination: Strip field conductor ends and secure them into the detachable terminal blocks. Ensure wire gauges do not exceed 12 AWG (2.5 mm sq). Route field cables through top or bottom cabinet wireways.
6. Pre-Power Inspection: Check that all terminal plugs are seated firmly, jumpers are correctly placed, and shield/protective earth grounds are connected.

Configuration and Maintenance Recommendations

• Fail-Safe Behavior (FAILOPT): Configure channel fail-safe options via Experion control software. In the event of an IOM communication loss or system hardware fault, individual channels can be programmed to hold their last state or shed to a safe zero condition.
• Relay Servicing: The socketed relay design allows for individual relay replacement. When replacing socketed units, use matching AgSnO2 contact assemblies.
• Contact Life Management: For highly inductive loads, confirm that inductive derating factors (such as PF = 0.4 or L/R = 100 ms) are respected to maintain contact longevity over the rated 50,000 electrical operations.
