Import Ab 1756-Ob32 — Buy in wholesale FOB from Supplier in China

The AB 1756-OB32 is a 32-point discrete DC output module for the Allen Bradley ControlLogix platform, sourcing 24V DC to field devices with high-density channel count in a single slot. This module provides 0.5A per channel with a 4A maximum per group and 8A per module, enabling substantial load aggregation for panel builders. Fujian Hongfei Automation Technology Limited Company distributes this module as part of their extensive DCS and PLC spare parts inventory, covering legacy and current Allen Bradley series. The 1756-OB32 features channel-level diagnostics including open wire, short circuit, and overload detection when paired with compatible electronic fusing configurations. Output groups are isolated from the backplane and from each other, providing 2500V AC isolation typical for ControlLogix DC output modules in this density class.

The module employs solid-state switching with typical output turn-on time of 0.5ms and turn-off time of 1.0ms, suitable for pulse-width modulation and fast-acting solenoid control applications. Each output point drives 24V DC loads through internal current limiting and surge protection, with thermal shutdown protecting the module from sustained overload conditions. The 1756-OB32 requires the 1756-TBCH 36-pin high-density terminal block or the 1756-TBS6H alternative for field connection, with wiring organised in four groups of eight outputs. Standard industry practice groups outputs by machine section or safety zone, leveraging the module's group isolation for fault containment. The high point count reduces per-point I/O cost in large installations, though thermal management becomes critical when loading all 32 outputs near maximum current simultaneously.

Applications for the 1756-OB32 span discrete manufacturing, packaging machinery, and material handling systems where numerous 24V DC solenoid valves, indicator lamps, and small contactor coils require coordinated control. System integrators favour this module for OEM panels where slot count in the ControlLogix chassis is constrained. Fujian Hongfei Automation Technology Limited Company sources from domestic and international channels, holding inventory across multiple automation brands for sectors including power generation, electronics assembly, and automotive manufacturing. Buyers should confirm current stock, exact module series revision, and whether terminal blocks are included when requesting quotation. The supplier's location in Fuzhou, Fujian Province provides access to both Xiamen Port and Fuzhou Port for export logistics, with inland connectivity to the manufacturing belts of coastal China.

Fujian Hongfei Automation Technology Limited Company operates from Fuzhou, Fujian Province, China, with postal code 350108. The supplier holds a harbor trust tier with a 0.00 percent platform response rate and zero recorded average response hours, suggesting limited engagement through automated channels. The company functions as a distributor, importer, wholesaler, and retailer of industrial automation equipment, maintaining inventory across DCS system spare parts, industrial robot components, servo systems, motor drives, frequency converters, sensors, and process instrumentation. Their stated market coverage includes power, electronics, metallurgy, chemical, automotive manufacturing, machine tools, packaging machinery, and general mechanical equipment sectors.

The supplier emphasises cooperation with abroad widely-known brands and lists extensive cross-brand inventory including Honeywell TDC series, Foxboro TRICONEX, Siemens S5/S7, Rexroth servo drives, and ABB robot components. Fujian Hongfei Automation Technology Limited Company does not disclose factory ownership, warehouse capacity, employee count, annual revenue, or specific client references. The profile indicates technical familiarity with obsolete and current automation product lines, including battery specifications, sealing rings, and amplifier model numbers. Buyers should verify current business registration, export licence status, and technical competency for the specific 1756-OB32 revision required before committing to purchase. Direct communication through multiple channels is advisable given the limited platform response metrics.
