Product Description

The F3YC16-0N is a high-reliability relay output module designed for the Yokogawa FA-M3 Range-free automation platform.

This module provides 16 mechanical relay output channels for switching both AC and DC loads, making it suitable for controlling:

• Solenoid valves

• Motor contactors

• Alarm annunciators

• High-current industrial control devices

The F3YC16-0N is designed with physical mechanical isolation, providing strong resistance to electrical noise, voltage surges, and field-side disturbances. This makes it especially suitable for legacy industrial equipment interfaces and high-voltage switching environments.

The module’s channel layout is organized into two independent common groups (8 channels per common) to simplify wiring and improve load management flexibility.

Technical Specifications

Industrial Usage

The F3YC16-0N is widely used in:

• Legacy industrial machinery upgrades

It is particularly effective for applications involving:

• High-voltage field equipment

• Inductive motor loads

• Systems requiring strong electrical isolation

Technical FAQ

What is the expected relay lifespan?

• Mechanical life: ~20 million switching cycles

• Electrical life: ~100,000 cycles under rated load

Periodic maintenance is recommended for high-frequency switching applications.

Can AC and DC loads be mixed on the same common terminal?
No. Each 8-point common group must use the same voltage type. Separate commons must be used when switching AC and DC loads simultaneously to maintain electrical safety and reliability.
