X20AIA744
The B & R Automation X20AIA744 module from the X20 Fieldbus Input Output Modules series is a compact analogue input unit designed to deliver precise and reliable signal acquisition in industrial automation environments. This module features 4 inputs supporting 16-bit resolution and accepts versatile Input Signal Ranges of 0–10 V, 0–20 mA, and 4–20 mA. Its lightweight design, with Dimensions (w x h x d) of 25 x 99 x 73 mm, facilitates Easy installation inside control cabinets rated to IP54 or higher. Power is supplied via the backplane at 24 V DC with a typical Current Consumption of 60 mA (at 5 V), ensuring minimal load on the fieldbus network. Early inclusion of Part Number X20AIA744, Manufacturer B & R Automation, and Series X20 Fieldbus Input Output Modules underscores the module’s pedigree and design intent.
Performance is underpinned by full-bridge strain gauge inputs operating in a 4-wire connection differential configuration. The module supports a high data throughput of 5000 samples per second per channel and features a conversion time of 500 µs at the strain gauge sensor. Input impedance is specified at Voltage: >1 MΩ and Current: <250 Ω, ensuring compatibility with a wide range of industrial transducers. Programmable input filtering employs a 2.5 kHz cutoff frequency to attenuate high-frequency noise, while Isolation (channel-to-bus and channel-to-channel) ensures robust signal integrity and eliminates ground loops. Status LEDs provide immediate diagnostics, with Module Status Indication displayed directly on the front panel. The operating ambient range of 0 °C to +60 °C and storage range of –25 °C to +70 °C allow adaptation to varied process environments without compromising performance.
Built for seamless integration, the X20AIA744 module delivers proven reliability in demanding applications such as load-cell measurement, process control, and machine monitoring. The unit supports installation up to 1000 m elevation without performance derating and can withstand relative humidity levels up to 0.95. Designed to meet international safety and EMC standards, the module carries CE, UL, ATEX, and UKCA certifications. Its IP20 enclosure is optimized for mounting within industrial cabinets, and twisted, shielded conductor wiring recommendations minimize electromagnetic interference. Whether used in food processing, packaging machinery, or heavy industry, the X20AIA744 offers a combination of precision, durability, and straightforward integration that aligns with modern automation requirements.
