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.
