Information About 1794-IE8H
The 1794-IE8H belongs to the Allen-Bradley FLEX I/O family, offering modular analog acquisition with HART protocol support for smart field instruments. Its design incorporates eight fault indicators, eight channel indicators, and a single power LED, along with a local microprocessor for advanced diagnostic and alarm handling. The module integrates easily with FLEX I/O terminal bases such as the 1794-TB3G and 1794-TB3GS, enabling flexible installation within distributed I/O architectures. Typical applications include process monitoring, transmitter diagnostics, and automation systems requiring configurable filtering, fault modes, and high-accuracy analog processing.
Key Features:
- Eight analog inputs: Single-ended, non-isolated channels for 0–20 mA and 4–20 mA signals.
- HART protocol support: Enables access to transmitter diagnostics and configuration data.
- High resolution: 16-bit successive-approximation conversion for precise measurements.
- Extensive indicators: Includes 8 fault LEDs, 8 channel LEDs, and one power LED.
- Configurable parameters: Supports input filtering, data formats, fault modes, and range settings.
- Compatible bases: Works with 1794-TB3G and 1794-TB3GS terminal bases.
- Fast response time: 80 ms step response to 99%.
- Industrial performance: Features 50 V continuous isolation between field side and system.
The 1794-IE8H delivers the reliability and precision required for accurate analog acquisition and HART diagnostics in distributed process automation systems.
