The Rockwell Automation and Allen-Bradley 1771-NOV is a voltage-only high-resolution isolated analog module. The module has 8 outputs each with an output range of +/-10 Volts DC. The 1771-NOV draws a 2.1 Amps current from the backplane at 5 Volts. The module has a maximum output impedance of 1 ohm, a 1.3-millivolt per bit output resolution with 13 bits with a sign bit, and an offset drift of +/-400 micro volts per degree Celsius. The 1771-NOV module has a minimum output drive capability of 1 kilo ohm at a maximum current of 10 milliamps.
The 1771-NOV has an output protection (overvoltage) of 140 Volts AC RMS (continuous) and a gain drift rating of +/-50PPM per degree Celsius. Additionally, the 1771-NOV’s maximum individual module update time is 25 milliseconds and calibration values at 0.0 per 10.0 Volts DC. The module has ramping values at a minimum of 1% of the full-scale range of 0.2 volts per second and when at a maximum of 200% of the full-scale range, the module has ramping values at 40 Volts per second.
The 1771-NOV has an accuracy with calibration (gain, offset and normal non-linearity) of 0.01% (full-range) at 25 degrees Celsius and a maximum 0.08 (full-range) at 25 degrees Celsius. The digital-analog converter for the 1771-NOV module takes 5 milliseconds as the settling time within 10% of the full scale into a resistive load. The 1771-NOV module is compliant with EMC standards and when not in use should be stored at temperatures not above 85 degrees Celsius and not less than -40 degrees Celsius.
