Allen-Bradley 1794-IE12 Flex I/O High Density Analog Module

Introducing the Allen-Bradley 1794-IE12 Flex I/O High-Density Analog Input Module

Precise Analog Input Specifications

• Channel Configuration: The 1794-IE12 provides twelve single-ended input channels supporting 0 to 20mA, 4 to 20mA, ±10V DC, and 0 to 10V DC signal types for maximum field device flexibility.
• Resolution & Accuracy: It features 16-bit 2's complement left-justified resolution with 320 μV/count for voltage and 0.641 μA/count for current. Absolute accuracy reaches 0.1% full scale at 25°C.
• Conversion Performance: The module uses successive approximation conversion with an 8.0 ms conversion rate for all channels simultaneously, ensuring synchronized data acquisition.
• Drift Characteristics: Accuracy drift measures only 0.004% full scale per degree Celsius for both voltage and current inputs, maintaining precision across temperature variations.

Power and Electrical Requirements

• External Supply: The 1794-IE12 requires a nominal 24V DC external supply with an operating range of 10.0 to 31.2V DC including 5% AC ripple.
• Current Consumption: It draws 80 mA from the FlexBus and has external supply current of 30 mA at 24V DC, 45 mA at 10V DC with 60 mA certification.
• Power Dissipation: Maximum power dissipation is 1.2W at 31.2V DC with thermal dissipation of 4.1 BTU/hour at maximum supply voltage.
• Isolation Rating: The module provides 50V continuous isolation with no isolation between individual channels for cost-effective high-density design.

Physical Characteristics and Mounting

• Compatible Bases: The 1794-IE12 requires 1794-TB3G or 1794-TB3GS terminal bases with keyswitch position 3 for fool-proof hardware installation preventing incorrect module mounting.
• Mounting Options: This module mounts on standard DIN rails with physical dimensions of 3.7 x 3.7 x 2.1 inches (94 x 94 x 53 mm).
• Status Indication: One combined green/red power/status LED provides visual indication of module condition and operational status.
• Enclosure Type: The unit features an open-style enclosure requiring appropriate cabinet protection for the installed environment.

Environmental and Mechanical Ratings

• Temperature Range: Operating temperature spans 0 to 55°C (32 to 131°F) with storage from -40 to 85°C (-40 to 185°F).
• Vibration Resistance: The module withstands 5g vibration at 10 to 500 Hz and 30g operating shock with 50g non-operating shock capability.
• Response Time: Input step response measures 1.3 seconds for standard operation with 0.09 seconds available in Quick Step mode.
• Overload Protection: Maximum input overload rating is 30V or 32 mA continuous for one channel at a time, protecting against field wiring errors.
