NFCP050-S15

The Yokogawa NFCP050-S15 is a CPU module for the FCN-RTU platform, combining an SH-4A (SH7730) processor, 128 MB of onboard flash memory, Ethernet communication, serial interfaces, and embedded I/O. It provides digital and analog signal channels alongside pulse inputs, allowing control processing and field signal handling within one module. The specified configuration is a basic type without explosion protection.

CPU and Embedded I/O

The module integrates processing, communications, and signal interfaces in a single unit. Its embedded I/O includes 16 digital inputs, 8 digital outputs, 12 analog inputs for 1-5 V signals, one additional analog input for 0-32 V signals, two analog outputs for 4-20 mA signals, and two pulse input channels.

The two analog outputs require an external power supply. The serial interfaces are specified as non-isolated, so electrical isolation must not be assumed when evaluating field wiring and interface requirements.

Communication Interfaces

The NFCP050-S15 provides one Ethernet port, three RS-232 ports, and one RS-422/RS-485 port. All four serial ports use RJ45 modular jacks. The three RS-232 ports are identified as SERIAL 1, SERIAL 2, and SERIAL 3; SERIAL 4 supports RS-422/RS-485.

The CPU and LAN status indicators provide operating information. HRDY indicates hardware readiness, RDY indicates system readiness, and CTRL indicates control readiness. The LAN indicators show network power status and link or activity, while RCV and SND indicate serial data reception and transmission.
