The Yokogawa S2EN501 is a Vortex Flowmeter Sensor (Primary Element) from the YEWFLO family. It is the part of the flowmeter that is inserted directly into the pipeline. Its function is to detect the vortices shed by a bluff body and generate a raw pulse signal proportional to the flow rate.

The Yokogawa A2EN501-S00000 is a complete, integrated Vortex Flowmeter from the YEWFLO E Series (often marked as models YF100, YF200, etc.). Unlike the sensor-only S2EN501 model, this unit is a one-piece flowmeter where the sensor and the converter (transmitter) are housed together in a single, compact enclosure.

The Yokogawa F3YC16-0N is a 16-channel Analog Input Module for the Yokogawa FA-M3 series of programmable controllers (PLCs). This module is designed to interface with a variety of analog field instruments, most commonly RTD (Resistance Temperature Detector) sensors, such as Pt100.

The Yokogawa F3YD14-5A is a 14-point Digital Output (DO) Module designed for the Yokogawa FA-M3 series of programmable controllers (PLCs). This module acts as an interface, converting the logic-level signals from the PLC's CPU into higher-power signals to control field devices such as solenoid valves, motor starters, contactors, indicator lamps, and other ON/OFF actuators.

The Yokogawa F3XU08-6N is an 8-channel Analog Output (AO) Module for the Yokogawa FA-M3 series of programmable controllers (PLCs). This module acts as a critical interface, converting digital values computed by the PLC's CPU into precise analog signals used to control field devices such as control valves, variable frequency drives (VFDs), proportional actuators, and analog indicators.

The Yokogawa F3XD16-4N is a highly reliable, 4-channel Digital Input Safety Relay module designed for use in Yokogawa's ProSafe-RS safety instrumented system (SIS).

Its primary function is to receive dry contact signals (e.g., from emergency stop buttons, pressure switches, limit switches, or other safety devices) and transmit the state of these signals to the ProSafe-RS safety controller for logic processing. As part of a certified SIS, it plays a critical role in monitoring the state of safety-critical field devices and initiating a safe shutdown or action when a dangerous condition is detected (e.g., a contact opening or closing).
