Yokogawa F3YC08-0C Relay Output Module for FA-M3 PLC Systems
Product Introduction
The F3YC08-0C belongs to the Yokogawa FA-M3 and FA-M3V programmable logic controller families. This module offers a relay contact output interface for switching a wide variety of external loads. Specifically, it provides eight output points, and every point is fully independent with its own common terminal. As a result, engineers can mix different load voltages on a single module without interference between channels. This flexibility makes the unit suitable for panels that combine DC solenoids, AC contactors, and indicator lamps.
Furthermore, the F3YC08-0C supports a rated load voltage of DC 5-24V and AC 100-240V. Each point carries a maximum load current of 2A, which covers most small and medium industrial loads. The isolation method uses mechanical contacts rather than semiconductors, so the output presents a true dry contact to the field wiring. Moreover, the response time is 10ms maximum for both OFF to ON and ON to OFF transitions, which suits general-purpose switching tasks.
Additionally, the relay contacts offer a long service life. Mechanical life reaches 20,000,000 operations or more, while electrical life reaches 100,000 operations or more. Besides, the module draws 205mA from the 5V DC backplane and needs no external power supply. The CPU error output HOLD/RESET function is not required for this model, and no surge protector is built in. Therefore, users should add external surge suppression when switching inductive loads.
Technical Specifications
The F3YC08-0C delivers eight relay contact outputs with all points independent. First, the rated load voltage covers DC 5-24V and AC 100-240V. The maximum load current is 2A per point. In addition, the response time is 10ms maximum in both directions. The isolation method relies on mechanical separation, which blocks DC and AC leakage paths between channels.
Moreover, mechanical life is rated at 20,000,000 operations or more, and electrical life is rated at 100,000 operations or more. Specifically, current consumption is 205mA at 5V DC, and no external power supply is required. The external connection uses an 18-point terminal block with M3.5 screws. Finally, the module has no built-in surge protector, so external protection is recommended for inductive loads.
Mechanical and Environmental Parameters
The F3YC08-0C weighs approximately 180g and connects through an 18-point terminal block with M3.5 screws. The operating temperature range is 0 to 55°C, while storage covers -20°C to 75°C. Besides, both operating and storage humidity range from 10 to 90% RH, non-condensing. The surrounding atmosphere must be free of corrosive gases, flammable gases, or heavy dust. However, note that the relays are not hermetically sealed, so dust and corrosive gases shorten relay life.
Silicone gases deserve special attention. Relays switched in an atmosphere containing silicone gases may form SiO2 deposits on contact surfaces, causing poor electrical contact. The risk is especially high under load conditions below 24V DC and 500mA. Therefore, in such environments, we recommend transistor output modules or other semiconductor-based modules instead.
Installation Guide
Installing the F3YC08-0C starts with choosing a panel location that meets the temperature and humidity limits. Next, mount the module in the FA-M3 base unit and confirm it seats firmly on the backplane. After that, wire the loads to the 18-point terminal block using M3.5 screws, and tighten each screw securely. Additionally, keep the enclosure free of dust and silicone-based materials to protect the relay contacts. Finally, add external surge suppression for inductive loads before applying power.
