The high-resolution 1771-NIV module is an analog input module by Allen-Bradley or Rockwell Automation which is part of the Allen-Bradley/Rockwell Automation 1771-N series of analog input modules. Equipped with 8 voltage and current input channels that is rated for +/-20mA (+/-5 Volts), the 1771-NIV module does not have any output channels. The 1771-NIV analog input module combines with programmable controllers like the Allen-Bradley PLC-5, PLC-3, and PLC-5/250 programmable controllers. The 1771-NIV module dissipates 6W of heat while it is in use and consumes about 1.2 Amps of backplane current from the 1771- chassis where it is connected. The 1771-NIV module takes a maximum of 5 seconds to detect if an input circuit is open and it has a rejection normal mode of 50/60dB while the typical common mode is 150dB. The typical AC signal delay has been set to range between 30 and 60 milliseconds with the typical DC signal delay set at 50 milliseconds.
From the factory, the 1771-NIV input module comes with an Allen-Bradley 1771-WH wiring arm and recommendations for use that would allow this module to work optimally. For instance, Allen-Bradley recommends that the 1771-NIV module be used with an RTP-4 for voltage inputs and an RTP-3 for the current inputs. In addition, the company also recommends that during the installation or removal of the 1771-NIV module, power be disconnected from the 1771 I/O chassis. As for the working environment, the 1771-NIV input module is designed to work effectively when the operating temperature is 0 to 60 degrees Celsius at 5 to 95% non-condensing relative humidity.

About 1771-NIV
The 1771-NIV module is a PLC 5 Analog I/O module manufactured by Allen-Bradley. It is part of the N-series and it features 8 inputs. It is powered with a backplane current of 1.5 Amps. This high-resolution module is used in industrial settings for block transfer programming. Block transfer programming is the process of moving input data from the memory of the module to the processor data table and vice versa within a single scan. The scan time is minimal and accurate. The 1771-NIV module can be rack-mounted in a panel. It has a small footprint to save space. The module supports the BDC/binary data format. The front of the I/O module has a RUN/FAULT indicator and a CAL/COM indicator. The RUN/FAULT indicator illuminates for block transfer with a flashing green light and it turns red when a fault is found during the transfer. The CAL/COM LED flashes during a block transfer and it flashes red during module calibration. There are 2 connector points on the front that host an 1771-NC cable.
The Allen-Bradley 1771-NIV PLC 5 Analog I/O module has a heat dissipation rating of 6 Watts with a backplane current of 1.2 Amps. The AC signal delay ranges between 30 and 60 milliseconds and the DC signal delay is set at 50 milliseconds. The module uses a 1771-WH wiring arm for optimal wiring and operation. The ambient environmental temperature should be set between 0 and 60 degrees Celsius for optimal operation with 5 to 95% non-condensing relative humidity. The 1771-NIV PLC 5 Analog I/O module has an open enclosure and it should be protected against dust, dirt, and water sprays.
The 1771-NIV module is an Allen-Bradley PLC 5 analog I/O module. It comes with a backplane current of 1.5 Amps.
