Product Description
The NFAI143-S50/S1 is a high-resolution, 4-channel analog input module developed by Yokogawa Electric Corporation for reliable signal acquisition in industrial automation systems. Designed for precision current loop monitoring, this module supports 4–20 mA and 0–20 mA signals with 16-bit resolution, ensuring high-fidelity data conversion for mission-critical control applications. It provides measurement headroom up to 24 mA, allowing stable processing of standard process transmitter outputs.
The NFAI143-S50/S1 features built-in linearization processing and automatic cold junction compensation, making it suitable for interfacing with temperature measurement devices such as thermocouples. Its rugged industrial design supports operation in harsh environments, with a temperature tolerance range of -20°C to +70°C, making it ideal for installation in non-climate-controlled control cabinets.
