Product Description

The F3YD14-5B is a high-reliability discrete transistor output module designed for the Yokogawa FA-M3 range-free automation platform.

This module provides 14 channels of high-speed DC switching outputs, primarily used for controlling:

• Solenoid valves

• Pilot lamps

• Relay coils

• Low-power DC actuators

The F3YD14-5B utilizes Sinking (NPN) transistor output logic, allowing efficient control of DC loads while minimizing mechanical wear associated with traditional relay switching.

A key design advantage of this module is optical isolation between internal logic circuits and external field wiring. This protects the PLC system from electrical noise, voltage spikes, and ground interference commonly encountered in industrial automation environments.

The semiconductor-based switching architecture provides:

• Ultra-fast response performance

• Long operational lifecycle (no mechanical wear)

• Stable high-frequency switching capability

This makes the module especially suitable for high-speed automation machinery.

Technical FAQ

What is the difference between transistor and relay output modules?
Transistor outputs provide faster switching speeds and longer service life since there are no mechanical moving parts. However, they are limited to DC load applications, whereas relay outputs can switch both AC and DC loads.

Does the F3YD14-5B require an external power supply?
Yes. A 12–24 V DC external power source is required for field-side loads, while the module’s internal logic circuitry is powered through the FA-M3 PLC backplane.
