Allen-Bradley 1794-IE8 Flex I/O Analog Input Module

Allen-Bradley 1794-IE8 Flex I/O High-Density Analog Input Module

Technical Specifications and Performance

• Input Channels: The module features eight (8) single-ended, non-isolated inputs that you can configure by wiring. It handles both current and voltage signals without needing hardware calibration.
• Signal Ranges: It supports 0 to 20 mA, 4 to 20 mA, +/-10 VDC, and 0 to 10 VDC input ranges. This flexibility allows it to connect to a wide variety of sensors and transmitters.
• Resolution & Accuracy: The 1794-IE8 offers a voltage resolution of 2.56 mV per count (unipolar) and 5.13 mV per count (bipolar). For current, it provides 5.13 µA per count. It maintains an absolute accuracy of 0.20% of full scale at 25 °C.
• Conversion Details: The module has a conversion rate of 256 µs per channel. The step response to reach 63% of the final value is 9.4 ms for voltage and 18.2 ms for current terminals.
• Environmental Tolerance: It operates reliably in temperatures from 0 to 55 °C (32 to 131 °F). It can withstand vibration of 5g at 10 to 500 Hz and is designed for demanding industrial environments.
• Power Requirements: The module draws 60 mA from the FlexBus and requires an external 24V DC nominal supply (10.0 to 31.2V DC range). Its maximum power dissipation is 3.0W at 31.2V DC.
• Drift and Stability: Accuracy drift remains low with temperature changes. It measures 0.00428% of full scale per °C for voltage inputs and 0.00407% per °C for current inputs.
• Physical Specifications: The module itself measures approximately 3.7 x 2.1 x 31.8 inches. It mounts on a DIN rail via the selected terminal base and features one green/red status indicator.
