Product Overview
The Yokogawa F3YC08-0N is an 8-point Relay Output Module designed for the FA-M3 PLC Series. It is used to control external electrical devices such as relays, solenoids, contactors, alarm devices, and indicator lamps by switching their circuits through mechanical relay contacts.
Compared with transistor output modules, the F3YC08-0N provides universal load compatibility (AC and DC) and strong electrical isolation, making it suitable for general-purpose industrial switching applications.

Function and Working Principle
The F3YC08-0N receives output commands from the PLC CPU and switches external loads using internal relay contacts.
When the PLC output signal is ON, the relay coil is energized, causing the contact to close and allow current flow to the connected field device. When the output is OFF, the relay de-energizes and the contact opens, stopping the circuit.
This mechanical switching mechanism provides full electrical isolation between the PLC control circuit and field devices, improving safety and allowing mixed-voltage operation.
Operating Sequence
- PLC CPU sends output command
- Relay coil is energized
- Contact closes (ON state)
- External device is powered
- Output turns OFF → relay releases
- Contact opens (OFF state)
