The Yokogawa SCP461-51 S1 is a high-performance, single-loop digital indicating controller from the dedicated SCP (Single-loop Controller for Pressure) series. The -51 model variant is specifically designed for applications requiring a linear analog current output for control, unlike the relay output version (-11).

The Yokogawa YHC415X-01 is a compact, single-loop Hybrid Recorder that combines the reliability of an analog trend record with the clarity and functionality of a digital display. It is part of Yokogawa's "YHC4000 Series" designed for simple, economical data recording and monitoring.

The Yokogawa CP461-50 is a versatile, single-loop, digital indicating controller from the UTAdvanced series. It is designed for a wide range of process control applications, including temperature, pressure, flow, and level control.

The Yokogawa SCP461-11 is a high-performance, single-loop, digital indicating controller designed specifically for precise pressure measurement and control applications. It forms part of Yokogawa's renowned SCP (Single-loop Controller for Pressure) series.

The Yokogawa CP461 is a processor (CPU) module used in the CENTUM VP Field Control Unit (FCU), forming the core control unit of the Field Control Station (FCS). It is designed for high reliability, continuous operation, and supports dual-redundant configurations. CP461 modules are replaceable with CP471 in some cases, with certain software/hardware requirements. It interfaces with various components via redundant network (Vnet/IP), communications and I/O modules. It includes memory protection during power failure, “READY” contact output for FCU status monitoring, and supports a certain number of node units in the system.

The GX90XA-10-U2N-CC is an analog input module in Yokogawa’s SMARTDAC+ / GM / GP series. It is a universal input, scanner type module (suffix “-U2”) with ten input channels. The module supports mixed input types including DC voltage, standard signals, thermocouples (TC), resistance temperature detectors (RTDs), digital inputs (voltage/contact), and DC current (when used with an external shunt resistor). It is used with GM or GP main units for data acquisition / recorder applications.

The Yokogawa NFDV561-P51 is a 32-channel Digital Input (DI) Module designed for the ProSafe-RS Safety Instrumented System (SIS). Its primary function is to read 24 V DC dry contact or sourcing (NAMUR) signals from field devices such as emergency stop buttons, pressure switches, level switches, limit switches, and solenoid valves.

The Yokogawa NFAI835-S51 is a high-performance, 8-channel analog input module designed for the ProSafe-RS Safety Instrumented System (SIS). It is engineered to interface with a wide range of critical field instruments by accepting low-level voltage signals from millivolt (mV) output sensors and thermocouples (T/C).

The Yokogawa NFAI135-S51 is a high-performance, 16-channel Analog Input Module designed for the ProSafe-RS safety instrumented system (SIS) or the CENTUM VP integrated production control system. It serves as a critical interface between field sensors and the control system, specializing in reading 4 to 20 mA DC current signals from devices such as pressure transmitters, temperature transmitters, flow meters, and valve positioners.

The Yokogawa NFSB100-S51 is a SB Bus Repeater Module designed for the Yokogawa STARDOM™ FCN-500 and FCN-100 series modular control systems. It serves to extend the communication range and enhance the signal integrity of the SB bus, which is Yokogawa's internal serial communication bus.
