Yokogawa F3XH04-3N 4-Channel Pulse Input Module
Product Introduction
The F3XH04-3N is a high-speed pulse input module built for the Yokogawa FA-M3 programmable controller. Specifically, it adds pulse-capture and interrupt features that detect input pulses shorter than the scan period. Therefore, machine builders use it for high-speed sensing, photomicro switch input, and encoder-style signal capture.
Technical Specifications
The module provides 4 input points with four independent input systems. Each point uses photocoupler isolation, so different signal systems can connect without interference. Rated input voltage is 24 V DC, and the operating range spans 20.4 to 26.4 V DC.
Rated input current is 11.2 mA per point at 24 V DC, with an input impedance of 2.1 KΩ. For ON status, the module needs at least 16.0 V DC and 7.2 mA. For OFF status, voltage must stay at or below 6.0 V DC and 2.5 mA.
Input response time is 50 µs max for both OFF→ON and ON→OFF transitions. Moreover, the minimum input pulse width is 50 µs, which suits fast sensing tasks. The input signal holds for 512 µs after an off-to-on transition is detected.
Pulse-capture and interrupt features are selected through DIP switches. However, these two features cannot operate at the same time. Interrupt settings are assigned per point through the FA-M3 Programming Tool WideField3.
Current consumption is 30 mA from the 5 V DC bus. The module connects through a 10-point terminal block with M3.5 screws, and the block includes terminals for shielded cables. Applicable conductor size is 0.33 to 0.82 mm², with a crimping torque of 0.8 N·m.
Mechanical and Environmental Parameters
The F3XH04-3N weighs 130 g and mounts in the FA-M3 base unit. It has no restriction on the CPU module type used alongside it. Operating temperature ranges from 0 to 55°C, and storage temperature ranges from -20°C to 75°C. Operating and storage humidity both span 10 to 90% RH without condensation. The surrounding atmosphere must be free of corrosive gases, flammable gases, and heavy dust.
Installation Guide
First, power down the FA-M3 base unit before inserting the module. Next, seat the F3XH04-3N into an available slot. Then, wire signals to the 10-point terminal block using shielded cable and suitable solderless terminals.
After wiring, set the DIP switches for pulse capture or interrupt mode. Specifically, configure interrupt points through WideField3. Finally, verify input response with a test pulse before starting production.
