Description

The 1746-NIO4I is an SLC 500 Four Channel Analog I/O module by Allen-Bradley. This module is combination module which comes with Two (2) inputs and Two (2) output points in a single slot module. It has 2 differential voltage or current input points and 2 current outputs with an overall backplane current draw of 55mA at 5 Volts and 14 5mA at 24 Volts. Its points have a common mode voltage of -20 to 20 Volts with a common module rejection signal of 105 dB at 60 Hertz and a Normal mode rejection signal of 55dB at 60 Hertz. The 1746-NIO4I uses the Sigma-Delta ADC converter with a converter resolution of 16 bits, +/-1 LSB, and 0.01% repeatability and Non-Linearity. Its normal input current ranges between -20 and +20 mA with a current impedance of 250 Ohms and a resolution of 1.22 A per LSB. The 1746-NIO4I has an overall accuracy of +/-0.642% at 0 to 60 degrees Celsius with a drift accuracy of +79 ppm/5 degrees Celsius and maximum gain and drift errors of +/- 0.556% and +/- 67ppm/ degrees Celsius.
