Product Overview
The Yokogawa F3YC08-0C is an 8-point Relay Output Module designed for the FA-M3 PLC Series. It is used to switch external electrical loads such as contactors, solenoids, indicator lamps, alarms, and small motors through mechanical relay contacts.
Unlike transistor output modules, the F3YC08-0C supports both AC and DC load switching, making it a flexible solution for mixed industrial control environments requiring electrical isolation and high load compatibility.

Function and Working Principle
The F3YC08-0C receives output commands from the PLC CPU and activates internal relay contacts to switch external loads.
When the PLC sends an ON signal, the relay coil energizes and closes the contact, allowing current to flow to the connected device. When the signal is OFF, the relay de-energizes and opens the contact, stopping the load.
Because it uses mechanical relays, the module provides galvanic isolation between control circuitry and field devices, improving safety and compatibility with different voltage levels.
Operating Sequence
- PLC CPU sends output command
- Relay coil is energized
- Contact closes or opens
- External load is switched ON/OFF
- Status feedback displayed via LED
- Cycle repeats
