F3YC08-0N Yokogawa FA-M3 Relay Output Module 8-Point

F3YC08-0N Yokogawa FA-M3 Relay Output Module | 8-Point Mechanical Isolation

The F3YC08-0N is an 8-point relay output module for the Yokogawa FA-M3 series. It uses mechanical isolation and handles DC 5-24 V and AC 100-240 V loads at 2 A per point. Each point shares a common terminal. The 10-point M3.5 screw terminal block simplifies field wiring. Response time is 10 ms max for ON and OFF. Mechanical life reaches 20 million operations. Electrical life reaches 100,000 operations. This module suits legacy FA-M3 systems that need direct relay switching. F3YC08-0N ships from Oiltech Controls with a 12-month warranty.

FAQ

Q: Can I use the F3YC08-0N in a panel with silicone sealant?

A: No. Silicone gas forms SiO2 on contacts and causes bad connections. Use transistor output modules in that environment.

Q: Why do my relay contacts fail early?

A: Dust, corrosive gas, and frequent switching shorten life. Check the enclosure and load current. Stay within 2 A per point.

Q: Should I pick relay or transistor output for my machine?

A: Pick relay for AC loads and mixed voltages. Pick transistor for high-cycle switching and low-voltage DC loads under silicone risk.

Q: How do I wire 8 points on one common?

A: The common carries up to 8 A total. Group loads by voltage. Keep each point at 2 A or less.

Q: What should I check before buying a used F3YC08-0N?

A: Ask for contact resistance readings, operation count, and photos. Confirm the FA-M3 CPU and rack slot match. Oiltech Controls tests each module before shipment.
