1746-NI4 Description

1746-NI4 Features

• Multi-Range Input Capability:​ Each channel independently configurable for voltage (0-10V, ±10V) or current (0-20mA, 4-20mA) inputs without hardware modifications
• High Resolution & Accuracy:​ 16-bit resolution (1 part in 32767) with exceptional measurement accuracy for precise process monitoring
• Individual Channel Configuration:​ Each of the 4 channels can be independently configured for different input types and ranges via software
• Open-Wire Detection:​ Built-in open-circuit detection for 4-20mA current inputs to identify sensor or wiring failures
• Channel-to-Channel Isolation:​ 500VAC isolation between field side and backplane, and 240VAC between channels for noise immunity
• Diagnostic Indicators:​ Comprehensive status LEDs for power, channel activity, and fault conditions
• Software Configurable:​ Easy setup via RSLogix 500 programming software with intuitive configuration screens
• Auto-Calibration:​ Software-assisted calibration routine maintains measurement accuracy over time
• Robust Industrial Design:​ Built to withstand harsh industrial environments with high noise immunity
