1794-IE12
The Allen-Bradley 1794-IE12 is a high-density analog input module from the Flex I/O product family. This module is
primarily used to interface analog devices such as Transmitters, indicators, recorders, single-loop and multi-loop controllers and other devices.
The 1794-IE12 comes with Twelve (12) analog input channels, configurable for 0 to 20mA, 4 to 20 mA, +/- 10VDC and 0 to
10 VDC input signal type. It has an integrated analog to digital conversion circuitry using successive approximation
method with resolution of 320 ?V/cnt for voltage and 0.641 ?A/cnt for current. The analog data format is stored in a 16-bit,
left justified register with 8.0 ms conversion rate on all channels. The absolute accuracy of the 1794-IE12 is 0.1% full
scale @ 25 °C for Voltage and current input with accuracy drift of 0.004% Full Scale/°C.
