Yokogawa F3YC08-0C Relay Output Module 8-Point

Product Overview

The Yokogawa F3YC08-0C is an 8-point relay output module for the FA-M3 series, providing isolated SPDT relay contacts for driving external loads. Each output is independently isolated, supporting both AC and DC loads from 5V DC to 240V AC at up to 2A per point. This versatility makes it ideal for controlling solenoid valves, motor starters, signaling lamps, and other mixed-voltage loads.

Compatibility & Applications

Installs in any FA-M3 I/O slot. Perfect for solenoid valve control, motor starter interfacing, alarm horn/lamp driving, heater contactors, and mixed AC/DC load applications where relay isolation and voltage flexibility are required.

FAQ

• Q: Can I switch AC and DC loads on the same module? A: Yes, each relay output is independent and can switch either AC (up to 240V) or DC (up to 24V) loads.
• Q: What is the maximum current per point? A: 2A per point, but observe total module power limitations and wire gauge ratings.
• Q: Are the outputs isolated from each other? A: Yes, F3YC08-0C features all-points-independent isolation, unlike F3YC08-0N which has grouped commons.
• Q: Should I use a snubber circuit? A: For inductive AC loads, external snubbers or varistors are recommended to extend relay contact life.

Installation Guide

1. Power off the FA-M3 system.
2. Insert F3YC08-0C into any available I/O slot.
3. Connect loads to the detachable terminal block (M3.5 screws).
4. For inductive loads, install external surge suppression devices.
5. Restore power and activate each output to verify relay operation and LED indication.
6. Monitor contact temperature during initial operation for any abnormal heating.

Selection Tips

• Use F3YC08-0C when you need isolated relay outputs for mixed AC/DC loads up to 2A.
• For higher point counts, F3YC16-0N provides 16 relay outputs with grouped commons.
• For faster switching (no mechanical wear), consider transistor output modules like F3YD08-6A or F3YD32-1P.
• Always size relay contacts for both steady-state and inrush current requirements.
