Yokogawa F3AD04-0N FA-M3 Series A/D Input Module

Product Overview

The Yokogawa F3AD04-0N is a 4-channel analog-to-digital (A/D) input module for the FA-M3 series. It converts analog voltage signals from sensors and transmitters into digital data with 50 μs conversion speed per point. Supporting multiple input ranges (0-5V, 1-5V, -10 to +10V DC) with differential inputs and 2 MΩ input impedance, it delivers high-accuracy measurement for process control applications.

FAQ

• Q: What is the conversion speed? A: 50 μs per point, enabling 200 μs total scan time for all 4 channels.
• Q: Can I mix input ranges on the same module? A: Yes, each channel can be independently configured for 0-5V, 1-5V, or ±10V ranges.
• Q: Does it support 4-20 mA current inputs? A: F3AD04-0N is voltage input only. For 4-20 mA, use F3AD08-1V or install external 250Ω precision resistors.
• Q: What happens if the CPU fails? A: Each channel can be set to either hold the last value or go to a preset safe value during CPU failure.

Installation Guide

1. Power off the FA-M3 system.
2. Insert F3AD04-0N into any available I/O slot.
3. Connect analog signal sources to the terminal block observing polarity.
4. Configure input ranges and scaling factors via WideField3 I/O configuration.
5. Set CPU failure response (hold/preset) for each channel as required by your safety strategy.
6. Restore power and verify analog values match expected sensor readings.

Selection Tips

• Use F3AD04-0N for 4-channel voltage input applications with fast 50 μs conversion.
• For 8-channel applications, consider F3AD08-1V or F3AD08-5R.
• For current input (4-20 mA), select F3AD08-1V or use voltage modules with external resistors.
• Verify signal source impedance is compatible with the 2 MΩ module input impedance.
