【英文介绍】

The Allen Bradley High resolution Isolated Analog module 1771-NR has 16-bit input resolution and 14-bit output resolution. The RTD excitation current of this module is 1ma(typical). Its input overvoltage protection is 140 volts AC RMS continuous, while offset drift is ±25 mΩ/ C and gain drift is ±50 ppm/ C. The unit has a calibration value of 1.00/649.0Ω and an input bandwidth of 9 Hz. It has a maximum update time of 25 milliseconds, making it time efficient; The overrange threshold of the machine is 0.9 Ω, and the overrange threshold is 650 Ω. The 1771-NR is offered as an open device for use in industrial environments that do not exceed pollution 2(as defined in EN/IEC0664-1) when applied in zone 2 environments. The enclosure should only be accessible through the appliance.

The power dissipation of 1771-NR is 5 V 6 W; Operating temperatures fluctuate between 0 and 60 degrees Celsius (32 to 140 degrees Fahrenheit), while storage temperatures fluctuate between -40 and 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The relative humidity of this module ranges from 5% to 95% without condensation. The maximum current of the backplane is 1.2 a. Before removing or installing an I/O module, disconnect the power supply from the socket in the 1771 I/O chassis and cables from the module. Failure to remove the power supply from the backplane can cause damage and performance issues, or even personal injury.
