Import Ab 1771-Ir/D — Buy in wholesale FOB from Supplier in China

The AB 1771-IR/D is a resistance temperature detector (RTD) input module from the Allen-Bradley PLC-5 series, manufactured for interfacing platinum, nickel, or copper RTD sensors with industrial control systems. This module converts analogue resistance signals from temperature sensors into digital data for PLC processing, supporting multiple RTD types with configurable input ranges. The 1771-IR/D occupies a single slot in the 1771 I/O chassis and communicates via the PLC-5 backplane, operating on 5V DC logic power from the chassis power supply. Input isolation and diagnostic capabilities are standard features, with channel-to-channel and channel-to-ground isolation typical for this module class to protect against ground loops and electrical noise in industrial environments.

The module utilises a 12-bit analogue-to-digital converter resolution, with input impedance and excitation current specifications matched to standard 100-ohm platinum (Pt100), 120-ohm nickel (Ni120), and 10-ohm copper (Cu10) RTD elements. Connection is via the 1771-WG or 1771-WN wiring arm, with screw terminals for field wiring. The typical accuracy specification for PLC-5 RTD modules is ±0.5°C or better at calibrated temperatures, with drift specifications of ±0.05°C per degree Celsius of ambient temperature change standard for this generation. The module supports both 2-wire and 3-wire RTD configurations, with 4-wire capability available on certain channel configurations depending on firmware revision and hardware revision level.

Primary applications include temperature monitoring in process industries such as chemical manufacturing, oil and gas refining, food and beverage processing, and pharmaceutical production. The AB 1771-IR/D is purchased by system integrators, maintenance departments in heavy industry, and automation distributors serving the legacy PLC-5 installed base. Buyers should confirm with Huge Technology Automation Co.,Ltd the exact revision level, firmware version, and whether the unit is new surplus, refurbished, or used, as these factors significantly affect compatibility with existing chassis and programming software. The supplier indicates availability of automation replacement parts across multiple brands including AB, ABB, GE, Schneider, and others.

Huge Technology Automation Co.,Ltd operates from Unit 901, Fengrun Financial Holding Group Building B, Site No.1008 Anling Road, Huli District, Xiamen, Fujian Province, China, with postal code 361006. The supplier holds a harbor trust tier designation, indicating a baseline verification level on the platform. The response rate is recorded at 0.00 percent with zero average response hours, which suggests either a new listing, limited platform engagement, or that response metrics have not yet accumulated sufficient data. The supplier's email contact is given as sales2(at)nseauto(dot)com.

The company profile indicates specialisation in industrial automation spare parts and components across multiple major brands. Their stated product range includes Bently Nevada proximity probes and proximitors, PLC systems from AB, ABB, GE, and Schneider, DCS platforms from ABB, Siemens, Foxboro, Westinghouse, and Yokogawa, and ESD systems from Triconex, HIMA, Bently, and ICS. The listing does not state manufacturing capability, factory certification, or specific quality control procedures.
