Information About 1794-IE8
The 1794-IE8 is part of the Allen-Bradley Flex I/O family, designed for use with Flex I/O communication adapters and installed on terminal bases such as 1794-TB2, -TB3, -TB3S, -TB3T, and -TB3TS. It provides eight configurable analog input channels that allow connection of field transmitters, recorders, controllers, and other analog devices. The module uses successive approximation conversion with a 16-bit 2’s complement data format, offering 12-bit resolution in unipolar mode and 11-bit plus sign in bipolar mode. With an absolute accuracy of 0.20% full scale at 25 °C and minimal drift, it ensures precise signal acquisition without requiring calibration. Powered by a 24 VDC supply and mounted on DIN rail, the 1794-IE8 supports reliable operation in distributed process control environments.
Key Features:
- Input Channels: Eight single-ended, non-isolated analog channels for voltage and current signals.
- Signal Types: Accepts 0–20 mA, 4–20 mA, ±10 VDC, and 0–10 VDC input ranges, compatible with standard field instruments.
- Conversion: Uses successive approximation with 16-bit 2’s complement data format for accurate processing.
- Resolution: Provides 12-bit resolution in unipolar mode and 11-bit plus sign in bipolar mode, ensuring precise measurements.
- Accuracy: 0.20% full scale at 25 °C with low drift (0.00428% FS/°C voltage, 0.00407% FS/°C current) for reliable long-term performance.
- Indicators: Includes a green/red LED for power and status indication.
- Installation: DIN rail mounted with terminal bases (1794-TB2, -TB3, -TB3S, -TB3T, -TB3TS) determining wiring options.
- Environmental Ratings: Operates from 0–55 °C, stores from –40–85 °C, and withstands 5 g vibration at 10–500 Hz.
The 1794-IE8 delivers the reliability and precision required for distributed analog signal acquisition in process automation.
