Yokogawa F3YC16-0N 16-Point Relay Output Module
A 16-point relay-contact output module for FA-M3 systems, with two eight-point common groups.
Product Overview
F3YC16-0N is the Yokogawa FA-M3 relay output module with sixteen mechanically isolated contact outputs arranged as two groups of eight points per common.
The module switches documented DC or AC loads and provides LED output indication. It contains neither an output fuse nor a surge-protection circuit, so branch protection and inductive-load suppression belong in the external design.
Yokogawa warns against mixing DC and AC loads on one module or using different AC sources on separate groups. Wiring must follow one approved supply strategy for the complete module.
Performance
Relay isolation
Uses mechanical relay contacts to separate field switching from the controller logic.
Dual common groups
Organizes sixteen outputs as two eight-point groups for controlled distribution.
Load switching
Supports documented resistive AC or DC loads within the point and common limits.
Visual status
Provides front-panel LED indication for the output states.

System Integration
Separate the supply strategy
Do not mix DC and AC loads on the same module or use different AC sources across groups.
Protect external circuits
Provide approved branch protection and suppression for inductive loads because the module has no internal fuse or surge protector.
Prove each output
Test polarity or phase, contact operation, load current and the safe state for all sixteen channels.
Applications
Machine interlocks
Switching approved contactor, solenoid or indication loads in an FA-M3 control panel.
Mixed process equipment
Providing isolated relay contacts where transistor output characteristics are unsuitable.
Controlled module exchange
Replacing a relay module while preserving the load and common-group schedule.
FAQ
Can DC and AC loads be mixed on F3YC16-0N?
No. Yokogawa instructs users not to mix DC and AC loads on one module.
Does F3YC16-0N include output fuses or surge suppression?
No. External branch protection and appropriate suppression for inductive loads must be provided.
What load schedule should accompany a F3YC16-0N enquiry?
Provide voltage type, steady and inrush current, switching frequency, common grouping and suppression for every point.
Can two different AC sources be used across the two common groups of F3YC16-0N?
No. Yokogawa warns against different AC sources on separate groups of the module.
What proves F3YC16-0N is ready after installation?
Verify all sixteen contacts, common-group wiring, load current, external protection, safe states and the complete output schedule.
