Yokogawa Analog Input Module NFAI135-S50
Standard Specifications
Current Input Module and Current I/O Module (Isolated Channels) The Current Input Module receives signals of 4 to 20 mA. The Current I/O Module receives and outputs signals of 4 to 20 mA. These two modules are isolated between the input/output signals and the system as well as between channels.
