Information About 1794-IF4I
The 1794-IF4I belongs to the FLEX I/O family, engineered to provide modular, space-saving input/output solutions. It features four individually isolated channels, configurable for voltage or current ranges including ±10 V, 0–10 V, ±5 V, 0–5 V, 0–20 mA, 4–20 mA, and ±20 mA. The module employs a Sigma-Delta A/D converter with selectable conversion times of 2.5 ms, 5 ms, or 7.5 ms for all channels. With 16-bit unipolar and 15-bit bipolar resolution, it achieves high accuracy of 0.1% full scale at 25 °C. The module draws 145 mA at 5.1 V and 125 mA at 24 V, while dissipating approximately 3 W. Depending on the terminal base used, it provides continuous isolation of 120 V or 250 V. It supports terminal bases including 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, and 1794-TBN, making installation flexible. With a temperature range of –20…55 °C and vibration/shock resistance, the 1794-IF4I is suitable for rugged industrial applications requiring precise analog data acquisition.
Key Features:
- Design: FLEX I/O isolated analog input module with 4 differential channels.
- Signal Support: User-configurable for current (0–20 mA, 4–20 mA, ±20 mA) and voltage (±10 V, 0–10 V, ±5 V, 0–5 V).
- Resolution: 16-bit unipolar, 15-bit bipolar with Sigma-Delta conversion.
- Accuracy: ±0.1% full scale at 25 °C; low drift across temperature.
- Conversion Rate: Selectable 2.5 ms, 5 ms, or 7.5 ms per module update.
- Isolation: Up to 250 V continuous, depending on terminal base used.
- Power Requirements: 145 mA at 5.1 V and 125 mA at 24 V DC.
- Status Indicators: Bi-color LED showing power, reset, configuration, and fault states.
- Mounting: DIN rail or panel mount with compatible FLEX I/O bases.
- Environmental Ratings: Operating –20…55 °C, 30 G shock, 5 G vibration, 5–95% RH non-condensing.
The 1794-IF4I delivers reliable, isolated, and precise analog input capability for distributed FLEX I/O systems in industrial automation.
