1771-NOC/B High Resolution Isolated Analog Module

✦ About the Product ✦

The Allen Bradley 1771-NOC/B is one edition in the High-resolution Isolated Analog Modules series. The high resolution and accuracy of this module allow the user to control processes with a tighter tolerance. The Allen Bradley 1771-NOC/B has 16-bit input and 14-bit output resolution. This module has 0.01% typical accuracy based on 65,000 count capability over Full-Scale Range (FSR). Equipped with programmable reset values for outputs, it selects the best reset value specified by the application requirements (each channel is configured independently). The 1771-NOC/B has a power dissipation of 5.5 Watts at 5 Volts. The operating temperature of this unit ranges from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit), and its storage temperature ranges from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). Its relative humidity is usually between 5% and 95% without condensation and it has a maximum backplane current of 1.1 A. Its output range fluctuates between 0 and 25 mA, and the output impedance of this module is > 1 MΩ while its output overvoltage protection is 140 Volts AC RMS continuous. The Offset Drift of this module is ±1.0 µA/degree Celsius, the Gain drift is ±50 ppm/degree Celsius, and its calibration value is 0.5 mA/22 mA. Its maximum update time is 25 milliseconds and has a ramping value of minimum 0.16 mA per second and maximum 32 mA per second. This module is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow the guidebook when handling this unit.
