Allen-Bradley | 1734-IE2C | POINT I/O

Product Description: Allen-Bradley 1734-IE2C

The Allen-Bradley 1734-IE2C is a 2-channel analog input module designed for the POINT I/O system. It accepts standard 4–20 mA current signals from industrial field devices such as transmitters and sensors, making it suitable for low-channel-count applications requiring precision analog monitoring. Its compact size and integrated diagnostics make it ideal for space-constrained and distributed I/O environments.

Key Features

• 16-bit resolution for accurate signal processing
• Built-in diagnostics: under-range, over-range, open-circuit detection
• Internal 250 Ω input impedance—no external resistor needed
• Per-channel LED indicators for status and fault monitoring
• Compatible with POINT I/O bases and Logix controllers
• Designed for DIN rail mounting in modular systems
