Import Ab 1769-Ob16 — Buy in Bulk from Supplier in China

The AB 1769-OB16 is a sixteen-channel 24V DC solid-state output module within the Allen-Bradley Compact I/O 1769 series, sourcing current to field devices from a common positive bus. N.S.E Automation Co., Ltd. lists this unit with factory packing and immediate quotation response, with lead time stated as 1-2 working days from their Fujian facility. The module delivers 16 discrete outputs at 0.5A per point with a 4A maximum per module, operating at 24V DC nominal with output voltage range of 10-30V DC. Each channel features individual LED indication and surge suppression for inductive load switching, with the module mounting on standard Compact I/O DIN rail alongside controllers in the CompactLogix family. The source indicates quantity one available at time of listing, with twelve months warranty coverage.

Output technology employs transistor switching with current sourcing configuration, meaning the module provides positive voltage to the load with return through field common. This architecture differs from relay-based alternatives like the 1769-OA8, offering faster switching speeds, longer operational life, and elimination of mechanical wear typical of electromechanical devices. The 1769-OB16 requires field power connection at 24V DC in addition to backplane logic power, with separate terminals for voltage distribution to output circuits. Thermal derating applies when ambient temperature exceeds 55 degrees Celsius, a standard characteristic for solid-state output modules in industrial enclosures without forced ventilation. N.S.E Automation cross-references this against ABB DSQC, DSDO, and DSTC series modules, indicating their stocking focus on European and North American automation brands alongside Allen-Bradley.

Buyers typically include controls engineers specifying new CompactLogix systems, maintenance departments replacing failed output cards in existing 1769 racks, and system integrators building standardised control panels for OEM machinery. Applications favour high-speed counting, solenoid valve manifolds, and indicator lamp circuits where solid-state reliability exceeds relay cycle life. The supplier emphasises lower support costs through replacement part availability and rapid quotation response. Importers should confirm output current per point against their load profile, verify whether the module is series A or B revision for compatibility with their controller firmware, and establish whether the quoted lead time represents domestic or export-ready availability from their Xiamen location.

N.S.E Automation Co., Ltd. maintains offices in Huli, Xiamen, with postal address in Xiame, Fujian Province, China, postal code 361006. The supplier holds a Harbor trust tier with zero recorded response rate and zero average response hours in the captured data, suggesting either a new listing or untracked communication performance. Their business positioning centres on automation replacement parts with emphasis on-premium brands including ABB, Allen-Bradley, and various European PLC and DCS module lines.

The listing presents quantity one available for the 1769-OB16 with factory packing and immediate email quotation response. No manufacturing capability, ISO certification, company history, employee count, or annual revenue figures appear in the source. The supplier cross-lists extensive ABB DSQC, DSDO, DSTC, and related part numbers alongside Allen-Bradley, indicating specialisation in discontinued or hard-to-source automation components. Contact is through email for pricing, with no named representative or telephone number provided in the extracted data.
