Product Overview
The Allen-Bradley 1734-IE2C POINT I/O module is designed for 2 single-ended, non-isolated current inputs, supporting precise industrial signal acquisition. It uses Delta Sigma conversion with 16-bit resolution to ensure highly accurate readings. Moreover, the module offers selectable 4–20 mA or 0–20 mA input ranges, making it flexible for diverse analog field devices. Network and input status indicators provide real-time diagnostic feedback during operation.
Key Functional Highlights
This compact analog input module improves process reliability and operational efficiency. Digital filtering reduces transient noise, while selectable 50 Hz or 60 Hz notch filters help eliminate frequency interference. Additionally, the module features temperature-stable accuracy, only drifting 30 ppm per degree Celsius, ensuring consistent measurements across industrial environments.
Advantages Include:
- 2 single-ended current input channels
- High resolution 16-bit Delta Sigma conversion
- Absolute accuracy of 0.1% full scale @ 25°C
- Input update rate: 100 ms (default)
- Compatible with 1734-TB, -TBS, -TOP, or -TOPS terminal bases
- Compact dimensions: 56 × 12 × 75.5 mm, weighing 33 g
Therefore, the 1734-IE2C module enables precise, reliable data acquisition for distributed I/O systems.
