Product Description

The 7AI774.70 developed by B&R is an excellent Analog Input Module. It is a part of the distinguished B&R 2003 series. This module, supporting up to 4 inputs with a measurement range of 0 to 20 mA and a resolution of 12 Bit, is designed for high precision and reliable data acquisition. Featuring a B&R 2003 screw-in module format, it integrates seamlessly into various automation systems. The module's measurement precision stands at +5 ?A at 25 degrees C, complemented by a maximum offset gain of 0.05% of final value to ensure accuracy. With a differential input resistance range of 130-200 ? (load), it is versatile enough for a variety of load conditions.

Dynamic characteristics include an input filter with a cut-off frequency of 225 Hz and attenuation of 60 dB, maintaining high signal integrity even in demanding environments. Despite its advanced capabilities, the module operates efficiently with a maximum power consumption of 0.4 W, making it suitable for energy-conscious applications. The module lacks electrical isolation between input and PCC or between inputs, yet it is robustly built for industrial settings. The 7AI774.70 is also C-UL-US Listed, confirming its adherence to stringent safety and quality standards.

The module is delivered in a specially designed box that offers protection during transportation and cabling, safeguarding the modules from dust and mechanical damage until installation. This careful packaging ensures that electricians can securely connect cables to terminal blocks and D-type connectors before the final installation of the controller. The 7AI774.70 is an essential component for modern automation systems, providing precise and reliable performance. Its combination of accuracy, efficiency, and robust design makes it a top choice for engineers and programmers seeking high-quality analog input solutions.
