Genuine Allen-Bradley 1746-OB32 SLC 32-Point Digital Output Module | SLC 500 Series – Verified Source
The Allen-Bradley 1746-OB32 is a cornerstone I/O module within Rockwell Automation’s SLC 500 control platform — one of the most widely deployed PLC families in discrete manufacturing, material handling, and process automation worldwide. Its 32-point sourcing DC output capacity makes it indispensable for high-density machine control applications. However, the global secondary market for SLC 500 modules is heavily saturated with counterfeit units, refurbished modules misrepresented as new, and grey-market stock with unknown service histories. Purchasing from unverified sources carries serious risks: premature field failure, voided OEM warranties, and potential safety incidents in critical control environments.
At Konmask, every 1746-OB32 unit we supply is sourced exclusively through verified, traceable supply channels. We apply a rigorous multi-step authentication process before any module ships — ensuring you receive a genuine, fully functional Allen-Bradley component backed by documentation. Our commitment to authentic, verified, and original hardware is not a marketing claim; it is a documented, auditable process that our industrial clients depend on for mission-critical installations.

Our 4-Step Quality Verification Process
Every 1746-OB32 unit supplied by Konmask passes through the following documented verification stages before dispatch:
- Step 1 — Source Authentication: We verify the supply chain origin of each unit. Modules are cross-referenced against known-genuine batch markings, date codes, and OEM packaging standards. Units from unverifiable sources are rejected at intake.
- Step 2 — Physical Inspection: Each module undergoes a detailed visual and mechanical inspection: PCB condition, connector integrity, label authenticity, housing markings, and absence of rework or repair indicators. High-resolution inspection photos are available on request.
- Step 3 — Functional Bench Testing: Modules are powered up and tested for correct output switching across all 32 channels using calibrated test equipment. Output voltage, current response, and isolation integrity are verified. A test report is available upon request.
- Step 4 — Documentation Package: Each shipment is accompanied by a Certificate of Conformance (COC), packing list, country of origin (COO) declaration, and optional third-party test report. All documents are traceable to the specific unit shipped.
Key Features & Benefits
- 32 Sourcing DC Outputs in a Single Slot: Maximizes I/O density within SLC 500 chassis, reducing hardware footprint and wiring complexity in high-channel-count applications.
- 1A per Point Output Rating: Supports a wide range of inductive and resistive loads including solenoid valves, relays, and indicator lamps without external amplification.
- 1500V AC Field-to-Backplane Isolation: Meets IEC 61131-2 isolation requirements for industrial PLC I/O modules, protecting the controller backplane from field-side transients.
- Removable Terminal Block Design: Enables module replacement without rewiring — critical for minimizing downtime during maintenance or module swap in live production environments.
- Wide Operating Temperature Range (0–60°C): Compliant with IEC 60068-2 environmental testing standards, suitable for panel-mount installations in non-climate-controlled industrial facilities.
- Full SLC 500 Platform Compatibility: Drop-in compatible with all SLC 500 fixed and modular chassis (1746-A4, A7, A10, A13) and supported by RSLogix 500 / Studio 5000 programming environments.
Typical Applications
- Automotive Assembly Lines: Controlling pneumatic actuators, conveyor drives, and part-present indicators in body-in-white and powertrain assembly stations.
- Food & Beverage Processing: Driving solenoid valves, filling heads, and reject gates in hygienic packaging and bottling lines requiring high I/O density.
- Material Handling & Conveyor Systems: Managing diverter gates, zone controllers, and accumulation conveyor drives in distribution center automation.
- Water & Wastewater Treatment: Controlling pump starters, valve actuators, and alarm outputs in SCADA-integrated treatment plant control panels.
- Machine Tool & CNC Peripherals: Interfacing with tool changers, coolant valves, and axis brake controls in legacy CNC machine retrofits retaining SLC 500 controllers.
- Building Automation & HVAC: Driving damper actuators, fan starters, and lighting control relays in large-scale building management systems using SLC 500 as the primary controller.
