AB 1794-IE12 Flex 12 Point Analog Input Module

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.

The 1794-IE12 is designed for use with the 1794-TB3G and 1794-TB3GS terminal bases. Only one terminal base is required per module. When installing the module to the appropriate terminal base, the intended keyswitch position is 3. Keyswitch position is a fool-proof hardware installation key preventing incorrect modules from being installed to incorrect terminal base.
