Product Overview
The Yokogawa F3YC16-0N is a 16-point Relay Output Module designed for the FA-M3 PLC Series. It is used to control external field devices such as contactors, solenoids, alarms, indicator lamps, and small motors by switching circuits through mechanical relay contacts.
With support for both AC and DC load switching, the F3YC16-0N is suitable for general-purpose industrial automation systems that require flexible output control and strong electrical isolation.

Function and Working Principle
The F3YC16-0N receives ON/OFF commands from the PLC CPU and activates internal relay coils to switch external loads.
When an output signal is ON, the relay energizes and closes the contact, allowing current to flow to the connected device. When OFF, the relay de-energizes and opens the contact, stopping the load.
This mechanical switching method provides complete galvanic isolation, ensuring safe operation when controlling different voltage levels.
Operating Sequence
- PLC CPU sends output command
- Relay coil is energized
- Contact closes (ON state)
- External device is powered
- Signal turns OFF → relay releases
- Contact opens (OFF state)
