Yokogawa Electric Corporation F3XH04-3N DC Input Module

The Yokogawa F3XH04-3N DC Input Module is a high-speed 4-point input card for FA-M3 PLC systems that accepts 24 VDC signals from field devices with pulse-detection capability, enabling rapid capture on fast automation lines. Each channel is a 24 VDC input rated for 11.2 mA, and the module uses photocoupler isolation to provide electrical isolation. With an ultra-high-speed response, this module supports pulse catch and rapid signal detection essential for counting, motion, and timing applications. It mounts in the FA-M3 base module, making it convenient for expanding or replacing standard inputs in industrial control panels and automation systems. Typical uses include proximity sensors, photoelectric sensors, encoders, and other pulse-capable devices on high-speed assembly lines, packaging equipment, and automated counting or motion control tasks. Common replacements for compatibility are F3XS04-3N, F3XD08-6F, and F3XD16-3H.
