The Allen-Bradley 1771-NB4S is an analog combination module that has 2 inputs and 2 isolated outputs. The inputs operate at a current range of between 4 and 20 milliamps while the outputs operate within a current range of 0 to 25 milliamps. The 1771-NB4S module exerts a current load of 1.6 Amps on the backplane. The 1771-NB4S module provides the required loop power to the 2-wire transmitters connected to its input terminals. Note that the 1771-NB4S module houses the functionality of the loop power. The module has a power dissipation rating of 7 watts and an operating shock rating of 30 g. When not in operation, the 1771-NB4S can accommodate a shock of 50 g and a temperature of between -40 and +85 degrees Celsius.
The 1771-NB4S module is meant to be operated within environments that have a temperature not exceeding 60 degrees Celsius and not below zero degrees Celsius. If the temperature keeps fluctuating by more than 5 degrees Celsius per minute, the performance of the module will slightly drop during the fluctuation moment. Additionally, the 1771-NB4S module reaches peak performance when operated at environments that have a relative humidity of between 5 and 95% without condensation. The 1771-NB4S supports communication using block transfer for read and write operations. The module has an update duration of 25 milliseconds (max), a 0.01% accuracy at 25 degrees Celsius (min) and 0.08% (max.). The module has a 1000 Volts DC isolation between the output channels and the input channels. Also the 1771-NB4S also has an overvoltage protection rated at 140 Volts AC, RMS.
