The 1794-IE12 is a FLEX I/O high-density analog input module manufactured by Rockwell Automation. It features 12 single-ended input channels, enabling it to convert analog current or voltage signals from industrial field sensors into digital data recognizable by the PLC.
Provides 12 channels
Hot-swap function
Flexible configuration
The Allen-Bradley FLEX I/O system offers a flexible, modular, and cost-effective solution for your industrial automation and control. The space saving design offers rack based I/O functionality of up to eight modules and provides digital, analog, HART analog, and specialty I/O with 4...32 points per module with flexible mounting and wiring options.The 1794-IE12 input module from Allen Bradley’s Flex I/O 1794 lineup serves as a vital interface in various automation applications. It ensures efficient functioning at an input power supply voltage typically rated at 24 volts DC but supports a range from 10.5 to 31.2 volts DC. The unit demands a FLEXBus current of 80 mA for operation, which is essential for its performance in distributed I/O setups.With a maximum continuous isolation voltage of 50 volts, this module guarantees protection against electrical faults. This feature enhances safety in installations by mitigating risks of cross-talk and disturbances.

When using the 1794-IE12, it is essential to ensure a stable external 24V DC power supply and properly configure the terminal base to prevent signal interference. Since this is a non-isolated single-ended module, you must strictly avoid common-mode voltages between channels that exceed specified limits. Additionally, before performing Removal and Insertion Under Power (RIUP), verify that the environment is safe and non-hazardous.
The 1794-IE12 is a 12-channel high-density analog input module from the Allen-Bradley FLEX I/O family. It converts analog signals from industrial sensors into digital data for PLC processing.
What input signal types does 1794-IE12 support?
It primarily supports standard current signals (4-20mA and 0-20mA) and voltage signals (+/-10V and 0-10V).
How do I physically install the 1794-IE12?
It must be mounted onto a compatible terminal base, such as the 1794-TB3 or 1794-TB3S, and then secured via a DIN rail.
What do the LED indicators on 1794-IE12 mean?
It typically features a Power LED, where steady green indicates the module is powered and operating correctly.
How to configure 1794-IE12 in software?
It is configured by adding the module to the I/O tree in Studio 5000 or RSLogix 5000 and setting the input ranges and digital filter parameters.
