Allen-Bradley 1756-IF6I Isolated Analog Voltage/Current Input Module

The Allen-Bradley 1756-IF6I is an Isolated Analog Voltage/Current Input Module. It has Six (6) individually isolated inputs and is part of the ControlLogix system. This module requires either the 20-pin 1756-TBNH or 1756-TBSH Removable Terminal Block (RTB) before it can be wired with input signals. You can choose between two data formats for the 1756-IF6I: the integer mode and the floating-point mode. It has 16 significant bits and you can select which range to use for every channel on your module among the series of operational ranges. The available ranges and their respective resolutions are as follows: +/- 10.5 Volts has 343 ?Volt/count, 0 to 10.5V has 171 ?Volt/count, 0 to 5.25 Volts has 86 ?Volt/count, and 0 to 21 milliamps has 0.34 ?A/count. When the isolated input module is operating beyond the limits set by the input range, the under-range/over-range detection feature will be activated.
