Product Description:
The 7AI351.70, manufactured by B&R, stands as a versatile Analog Input Module designed for precision and flexibility in industrial applications. This module supports both voltage and current measurements, accommodating inputs ranging from +/- 10 V to 0-20 mA with a 12 Bit + sign resolution. It is equipped with a B&R 2003 screw-in module configuration, offering seamless integration into automation systems requiring reliable analog data acquisition.
The 7AI351.70 module is adept at handling potentiometer operations, providing precise voltage readings up to +9.94 V at a maximum current of 10 mA. This module features a mode switch for easy selection between voltage and current measurement modes, ensuring compatibility with diverse operational requirements. The 7AI351.70 includes advanced features such as differential input resistance of 20 M? for voltage measurements and 130-200 ? for current measurements, optimizing accuracy across varying load conditions. With a low power consumption of 0.3 W during current/voltage measurement and 0.7 W in potentiometer operation dynamic, it operates efficiently without compromising performance. This module maintains high signal integrity with a cut-off frequency of 1 kHz and attenuation of 60 dB, suitable for applications demanding precise analog signal processing.
Compatibility extends to controllers like the 2003 PCC CPU, Remote I/O Bus Controller, and CAN Bus Controller, ensuring versatile deployment options in automation networks. Additionally, the 7AI351.70 module incorporates a polymer PTC protective element, offering robust overload and short circuit protection. In case of an overload or short circuit event, the protective element becomes highly resistive, interrupting current flow until the fault is rectified and the module reset, ensuring reliable operation and safeguarding connected equipment from potential damage.
