Beskrivelse
Allen-Bradley 1794-IF8IH FLEX I/O HART Analog Input Module
The Allen-Bradley 1794-IF8IH is a FLEX I/O HART analog module featuring 8 isolated single-ended inputs. Using Sigma-Delta conversion with 16-bit unipolar and 15-bit bipolar resolution, this module provides reliable analog signal acquisition. Operating on 19.2 to 31.2 V DC, it consumes 4.8 W maximum. Weighing approximately 0.5 kg (1.1 lbs), it measures 3.7 x 3.7 x 2.6 inches and operates from 32°F to 131°F.

Compatible Terminal Bases
- 1794-TB3
- 1794-TB3S
Installation & Field Application Guide
- Mount the module on a compatible terminal base (1794-TB3 or 1794-TB3S). Ensure secure seating.
- Use shielded wiring for signal connections. Signal ports are wiring category 2; power ports are wiring category 3.
- Verify external DC voltage is between 19.2 and 31.2 V DC with less than 5% AC ripple.
- Field calibration is available if factory calibration does not meet application requirements.
Why Choose the 1794-IF8IH
- 8 isolated HART analog inputs with Sigma-Delta conversion for high accuracy.
- 16-bit unipolar and 15-bit bipolar resolution for flexible signal measurement.
- North American Hazardous Location approval for safe operation in industrial environments.
- Field calibration capability allows in-situ adjustment without factory return.
Field Engineer FAQs
Q1: What is the difference between isolated and non-isolated inputs on this module?
A1: The 1794-IF8IH provides isolated inputs, meaning each channel is electrically separated from the module's backplane and other channels, reducing ground loop noise and protecting the system from field-side faults.
Q2: Can this module communicate HART data?
A2: Yes, the 1794-IF8IH supports HART communication, allowing access to device diagnostics and configuration parameters from connected HART field instruments.
Q3: What wire size should I use for the 1794-IF8IH?
A3: Wire size depends on the terminal base used. Refer to the terminal base documentation. Use shielded wiring for signal ports (category 2) and appropriate gauge for power ports (category 3).
