About the Allen-Bradley 1734-IE8C

The 1734-IE8C is a POINT I/O 24V DC 8 channel high density analog current input module. Its 8 inputs are single-ended and non-isolated, with ranges of 4 to 20 mA and 0 to 20 mA, 16 bit resolution at 0.32 µA/cnt and absolute accuracy of 0.1% full scale at 25 °C. It mounts on DIN rail on a 1734-TB, 1734-TBS, 1734-TOP or 1734-TOPS terminal base.

What is the 1734-IE8C used for?

It reads 8 current loops and reports them as signed integer data, using Delta Sigma conversion. It draws 75 mA at 5V DC from the POINTBus, takes field power of 10 to 28.8V DC, and its inputs are fault protected to 28.8V DC.
