As a critical component in Industrial Automation and Control Module architectures, the 1746-OW16/C delivers robust, galvanically isolated switching across a wide voltage range of 5V to 265V AC/DC — making it indispensable for process control, machine automation, and facility management environments. Every unit we supply is 100% Brand New and Factory Sealed, sourced directly from authorized channels to guarantee authenticity and performance.

Procurement managers and site engineers operating SLC 500-based PLC Systems frequently encounter the challenge of sourcing reliable, Original New Spare Parts for aging or active control infrastructure. The 1746-OW16/C addresses this need precisely — its conformal-coated PCB (denoted by the /C suffix) provides enhanced resistance to moisture, dust, and chemical exposure, extending service life in harsh industrial environments. Whether deployed in Oil & Gas facilities, power distribution panels, or discrete manufacturing lines, this module integrates seamlessly into existing SLC 500 chassis without requiring software reconfiguration.

With fast global shipping, a 1-year warranty, and full technical support for EOL legacy systems, sourcing the 1746-OW16/C from us means zero compromise on quality or lead time. Contact our team today for a competitive quote.

Technical Specifications & Selection Guide

Selection Tip: Choose the 1746-OW16/C over the standard 1746-OW16 when your installation environment involves elevated humidity, airborne particulates, or chemical vapors. The conformal coating provides a critical layer of PCB protection without any change to electrical performance or software configuration.

FAQ — Frequently Asked Questions

Q1: What is the price of the 1746-OW16/C, and do you offer volume discounts?
A: Pricing for the 1746-OW16/C is competitive and varies based on order quantity and delivery urgency. We offer tiered volume discounts for orders of 5 units or more. Contact sale@ninermas.com with your required quantity and delivery location for a formal quotation within 2 business hours.

Q2: What is the lead time for the 1746-OW16/C?
A: In-stock units ship within 1-2 business days. For bulk orders or specific revision requirements, standard lead time is 3-7 business days. Expedited freight options are available for critical shutdowns or emergency replacements.

Q3: Can you provide a Datasheet or Certificate of Conformance for the 1746-OW16/C?
A: Yes. The official Allen-Bradley 1746-OW16/C datasheet, installation instructions, and certificate of conformance are available upon request. Simply email sale@ninermas.com with your order reference or inquiry number.

Q4: What is the difference between 1746-OW16 and 1746-OW16/C?
A: The /C suffix designates a conformal-coated PCB revision, providing enhanced protection against moisture, dust, and chemical contaminants. Electrically and functionally, both variants are identical and interchangeable within SLC 500 chassis.

Q5: Is this module 100% Original and Brand New — not refurbished or repaired?
A: Absolutely. Every 1746-OW16/C we supply is 100% Original and Brand New, factory sealed in original Allen-Bradley packaging. We do not sell refurbished, repaired, or counterfeit components. Authenticity documentation is available upon request.

Q6: Is the 1746-OW16/C compatible with ControlLogix or CompactLogix platforms?
A: No. The 1746 series is exclusively designed for the SLC 500 platform. For ControlLogix applications, the equivalent module is the 1756-OW16I. Our team can assist with cross-referencing if you are migrating platforms.
