Genuine Allen-Bradley 1757-SRC1 Cable Redundancy Module | ControlNet Series – Verified Source
The Allen-Bradley 1757-SRC1 Cable Redundancy Module is a mission-critical component within Rockwell Automation’s ControlNet redundancy architecture, widely deployed in high-availability process control environments including oil & gas, power generation, and continuous manufacturing. As a discontinued yet operationally indispensable part, the 1757-SRC1 commands a premium on the secondary market — and with that premium comes significant risk. Counterfeit and refurbished-as-new units are prevalent, often lacking proper firmware, exhibiting degraded backplane connectors, or failing under thermal stress within weeks of installation. Sourcing from unverified channels can result in unplanned downtime, safety incidents, and costly system audits.
At Konmask, every Allen-Bradley 1757-SRC1 we supply is individually inspected, tested, and documented before shipment. We source exclusively through verified industrial distribution channels and maintain full traceability from origin to delivery. Our commitment to genuine, authentic, and verified parts is not a marketing claim — it is a documented process backed by certificates, test data, and photographic evidence available to every buyer upon request.

Our 4-Step Quality Verification Process
- Step 1 — Visual & Physical Inspection: Each unit is examined under controlled lighting for label authenticity, housing integrity, connector pin condition, and absence of re-marking or sanding. Counterfeit indicators (misaligned logos, incorrect font weights, non-OEM screws) are cross-referenced against genuine reference units.
- Step 2 — Functional Power-On Test: The module is bench-tested in a compatible ControlNet rack environment. We verify backplane communication, LED status indicators, and firmware version against Rockwell Automation’s published firmware matrix.
- Step 3 — Documentation Compilation: We prepare a unit-specific package including: Certificate of Conformance (COC), photographic record (label, connectors, PCB where applicable), Packing List with serial/lot traceability, and Country of Origin (COO) Declaration.
- Step 4 — Pre-Shipment Final Check: Weight, dimensions, and packaging integrity are verified. ESD-safe packaging is applied. A final inspection sign-off is recorded. Test reports are available upon request prior to or after shipment.
Key Features & Benefits
- Dual-Cable Media Redundancy: Provides automatic failover between primary and secondary ControlNet cables, eliminating single points of network failure in compliance with IEC 62439 high-availability network principles.
- Seamless Integration with 1757 Series: Designed for direct compatibility with Allen-Bradley’s ControlNet redundancy chassis and 1757-SRCP redundancy controller pairs, minimizing integration engineering effort.
- Bumpless Switchover: Cable fault detection and switchover occur without disrupting I/O communication or triggering controller faults — critical for continuous process industries per ISA-18.2 alarm management standards.
- Extended Service Life Support: Konmask maintains stock of legacy ControlNet components, enabling plant life extension (PLEX) programs without full DCS/PLC migration.
- Full Traceability: Every unit ships with documented origin, inspection records, and test data — supporting your site’s spare parts qualification and audit requirements.
- Global Compliance Ready: Units are verified for CE and UL markings where applicable, supporting import compliance in EU, North American, and Asia-Pacific jurisdictions.
Typical Applications
- Oil & Gas: Upstream wellhead control panels and downstream refinery DCS networks requiring ControlNet media redundancy for SIL-rated loops.
- Power Generation: Turbine control systems and substation automation where network uptime is mandated by NERC CIP or IEC 61850 operational standards.
- Continuous Chemical Manufacturing: Reactor and distillation column control networks where any communication interruption risks batch loss or safety shutdown.
- Water & Wastewater Treatment: SCADA-integrated pump station and treatment plant PLCs requiring redundant field network paths.
- Automotive Assembly: High-speed production line PLCs where ControlNet redundancy prevents line stoppages and OEE degradation.
- Mining & Minerals Processing: Conveyor, crusher, and flotation cell control systems in harsh environments demanding robust network redundancy.
