Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1746-NI4 is a four-channel analog input module in the Allen-Bradley SLC 500 platform. It provides selectable voltage (-10 V to +10 V DC) or current (-20 mA to +20 mA) differential inputs for precise signal acquisition in industrial control systems. Installed in an SLC 500 chassis, it interfaces sensors or transducers to PLC logic. Typical applications include process monitoring, analog sensor signal collection, and control feedback loops where accurate analog measurement is required. Part number 1746-NI4 integrates into standard SLC 500 architectures.
