Mitsubishi's FX-16NP is a specialized interface unit that facilitates communication between the FX programmable controller and the MELSECNET/MINI-S3 network. This device is intended for use as a local station or as a remote I/O module interfacing with A2C-type CPUs. The FX-16NP supports the transmission of 16 I/O points—8 inputs and 8 outputs—ensuring efficient data flow within automated systems.
In terms of configuration, this unit occupies 2 stations on the network while supporting a maximum of 64 stations, allowing for extensive scalability within your setup. The unit provides a robust optical fiber cable system for station-to-station connections, making it ideal for maintaining signal integrity over distances of up to 50 meters. It specifically requires plastic fiber cables for proper operation, with the optical fiber featuring an outside diameter of 1 mm.
Transmission losses for the cable are minimal at 260 dB/km (853 dB/kft), which supports stable connections over longer distances. The configuration allows a bend radius of at least 25 mm (0.98 inches), ensuring installation flexibility. Power requirements for communication operation are 24V DC within a tolerance of +30% to -35%, consuming 0.12A from a stabilized power supply. The interface unit draws 5V DC at 80 mA from an internal power supply integrated within the FX or FX2C controllers.
