Product Overview

The Yokogawa F3YD32-1P is a 32-point transistor output module designed for the FA-M3 PLC Series. It provides reliable DC output switching for industrial automation systems, enabling the control of multiple field devices such as relays, solenoids, lamps, and actuators.

This module uses a sink-type transistor output structure, optimized for stable, low-noise, and high-density control applications in machine automation and process control systems.

Technical Specifications

Function and Working Principle

The F3YD32-1P receives output commands from the PLC CPU and switches DC field loads electronically using transistor switching elements.

When an output is ON, the transistor conducts current and powers the connected device. When OFF, it stops conduction immediately. This allows fast, silent, and wear-free switching, ideal for repetitive automation tasks.

Unlike relay outputs, there are no mechanical contacts, so durability and switching speed are significantly improved.

Operating Sequence

1. PLC CPU sends output signal
2. Photocoupler isolates control circuit
3. Transistor output stage activates
4. DC load is energized
5. Output switches OFF → transistor stops conduction
6. Load is de-energized
