FAQ for 1756-IF16K
The Allen-Bradley 1756-IF16K is a member of the ControlLogix Analog I/O Modules series. The 1756-IF16K is a Non-isolated Analog Voltage/Current Input Module. This module has 3 wiring methods. There are the Single-ended Wiring Method, Differential Wiring Method, and the High-speed Mode Differential Wiring Method. Single-ended Wiring compares one side of the signal input to the ground signal. This difference is used for generating digital data for the controller. Differential wiring methods are recommended for applications that use separate signal pairs and differential cables are recommended for environments where sound immunity is required. Remember, this wiring method lets you only use half of the channel modules. You can only use eight channels on the 1756-IF16K module. The High-speed Mode Differential Wiring Method provides the fastest data update possible. When using high-speed mode, there are some specific conditions. The condition uses the differential wiring method and allows the use of one out of every four channels in the module.
The input of this module is 16 single-ended. The current draw at 5.1 V DC of this module is 150 mA. The current draw at 24V DC of this module is 65 mA.
