YOKOGAWA NFAI543-S50 Current Output Module

Description

The YOKOGAWA NFAI543-S50 Current Output Module is a dedicated analog current output component designed for industrial automation systems. It features a current sink output format, with 16 independent channels each supporting a 4 to 20 mA current output signal. Key electrical specifications include a maximum output ON voltage of 2 V DC, a maximum off-state leak current of 0.1 mA, and a maximum load current of 100 mA per channel at 26.4 V. The module meets strict isolation standards: it has a withstanding voltage of 2 kV AC for 1 minute between output signals and the system, and 500 V AC for 1 minute between commons (common minus side every 16 channels). Built with integrated isolation functionality, it ensures safe and reliable signal transmission in demanding industrial environments. It supports standard switching response redundant configurations (excluding explosion protection), enabling dual redundant setups when paired with an identical module of the same suffix code. The module is compatible with multiple hardware platforms, including ESB bus local node units such as ANB10S and ANB10D, as well as ER bus remote nodes, making it suitable for a wide range of industrial control and monitoring applications.
