Genuine Allen-Bradley 1775-KA Communication Adapter | PLC-5 Series – Verified Source
The Allen-Bradley 1775-KA Communication Adapter is a mission-critical interface module within Rockwell Automation’s PLC-5 control platform — a backbone of heavy industry, power generation, and process automation worldwide. As production of legacy PLC-5 components winds down, genuine 1775-KA units have become increasingly scarce, making the market vulnerable to counterfeit modules, refurbished-as-new stock, and grey-market parts that carry no warranty and pose serious operational risk. A failed or non-genuine adapter can cause communication faults, unplanned downtime, and safety incidents in live production environments.
Konmask sources every 1775-KA unit through verified industrial supply channels with full traceability. Each module is inspected against Allen-Bradley factory specifications before dispatch. Our listings carry the terms genuine, verified, and authentic because we back them with documentation — not just words. When you order from Konmask.com, you receive the exact part you paid for, supported by a transparent quality record.

Our 4-Step Quality Verification Process
- Step 1 — Source Authentication: Every unit is procured exclusively from traceable industrial distributors or OEM-authorized channels. Supplier credentials, purchase invoices, and chain-of-custody records are retained on file. No anonymous or unverified sources are accepted.
- Step 2 — Physical Inspection: Incoming modules are inspected against Allen-Bradley factory markings, label integrity, date codes, PCB revision stamps, and housing condition. Any unit showing signs of remarking, repainting, or tampered serial numbers is rejected and quarantined.
- Step 3 — Functional Bench Test: Where applicable, modules undergo powered bench testing to confirm communication handshake, backplane response, and LED status behavior consistent with factory specifications. Test results are logged and available upon request.
- Step 4 — Documentation Package: Each shipment is accompanied by a Packing List, Certificate of Conformance (COC), Country of Origin (COO) Declaration, and — on request — a Test Report and photographic evidence of the specific unit shipped. We can also provide a copy of the original manufacturer datasheet.

- Full Documentation Traceability: Every Konmask unit ships with COC and COO documentation, supporting ISO 9001 procurement audit requirements.
- Genuine Part — No Substitution Risk: Unlike grey-market alternatives, genuine 1775-KA modules carry factory firmware and hardware revisions that ensure compatibility with existing PLC-5 programs without unexpected faults.
Typical Applications
- Oil & Gas: Pipeline SCADA systems and wellhead control panels using legacy PLC-5 platforms requiring DH+ network communication.
- Power Generation: Turbine and boiler control systems in coal, gas, and hydroelectric plants where PLC-5 controllers manage distributed I/O over RIO networks.
- Automotive Manufacturing: Assembly line PLCs communicating with HMI stations and MES systems via Data Highway Plus in body-in-white and paint shop environments.
- Water & Wastewater Treatment: Pump station and treatment plant automation where 1771-chassis PLC-5 systems coordinate remote I/O across large geographic footprints.
- Mining & Minerals Processing: Conveyor, crusher, and flotation cell control systems relying on PLC-5 DH+ networks for supervisory communication.
- Chemical & Pharmaceutical: Batch process controllers in regulated environments where validated PLC-5 configurations cannot be easily migrated and require authentic spare parts to maintain system qualification.

Authenticity & Trust FAQ
Q: How can I verify that the 1775-KA I receive is genuine Allen-Bradley?
A: Every unit shipped by Konmask includes a Certificate of Conformance (COC) and Country of Origin Declaration. Upon request, we provide pre-shipment photographs of the specific unit, including label, PCB, and serial number. You may cross-reference the date code and revision marking against Allen-Bradley’s published documentation. If you have access to a PLC-5 test bench, we encourage incoming inspection — genuine units will communicate correctly without firmware errors.
Q: What is your warranty and return policy?
A: Konmask offers a 90-day warranty against defects in materials and workmanship for all verified genuine parts. If a unit fails within the warranty period under normal operating conditions, we will replace it or issue a full refund. Units must be returned in original packaging with the original documentation. Warranty does not cover damage caused by incorrect installation, overvoltage, or environmental conditions outside the manufacturer’s specifications.
Q: Can you provide a test report or inspection photos before I pay?
A: Yes. For orders of 2 or more units, or for any single-unit order above USD $500, we can provide pre-shipment inspection photos and a functional test report at no additional charge. For smaller orders, photos of the specific unit are available upon request. Please indicate your documentation requirements when submitting your inquiry and we will confirm availability before invoicing.
