Product Overview
YOKOGAWA F3XD64-3N is a high-performance digital input module launched by Yokogawa Electric Corporation in Japan. It belongs to the FA-M3 series programmable logic controller (PLC) supporting I/O module system and is designed specifically for the signal acquisition requirements of industrial automation control systems. This module has core advantages such as high integration, wide voltage adaptation, and stable anti-interference. It can accurately and efficiently transmit various digital signals on site to the PLC main controller, providing reliable data support for precise control of automated production lines. Its product positioning covers medium to large-scale industrial automation projects, suitable for various complex industrial environments, originating from Japan, with strict industrial grade quality control standards to ensure long-term stable operation.
Core functional features
1. Universal dual-mode input design
The module adopts a dual-mode compatible design of sink current and source current, which can flexibly adapt to different types of field input devices without additional configuration. It can directly connect industrial sensors such as proximity switches, photoelectric sensors, and travel switches, as well as manual control devices such as buttons, micro switches, and conversion switches, covering a wide range of digital signal acquisition scenarios in industrial sites. This universal design significantly reduces the difficulty of system selection, enhances module universality and application flexibility, and reduces spare parts inventory pressure.
2. High integration signal acquisition capability
The module integrates 64 independent digital input points and adopts an 8-point/common grouping design, which can achieve centralized acquisition of a large number of signals and improve anti-interference ability through group isolation. The 64 point high integration design can effectively reduce the rack space occupied by modules, simplify the on-site wiring architecture, reduce system installation costs and maintenance difficulties, and is particularly suitable for signal centralized acquisition scenarios with multiple sensors and control points in large production lines, such as machine tool clusters, chemical reactor groups, etc.
3. High precision and fast response performance
The module has configurable input sampling time and supports precise adjustment of four levels: 0 μ s (normal), 62.5 μ s, 250 μ s, and 1ms (depending on specific CPU modules such as F3SP22, F3SP28, etc.). The actual response time in default state is about 100 μ s (Off → On) and 300 μ s (On → Off), which can quickly capture the status changes of on-site equipment and avoid control deviation caused by signal delay. For CPU modules that do not support gear adjustment, the response time can still be guaranteed to be below 1.0ms for Off → On and below 2.5ms for On → Off, meeting the real-time control requirements of the vast majority of industrial scenarios.
4. Reliable isolation and protection mechanisms
The module adopts a photo coupler internally to achieve electrical isolation between the input signal and the internal circuit. The withstand voltage between the external connection terminal and the internal circuit can reach 1500V AC/1 minute, effectively blocking the influence of on-site interference signals on the control system and improving the stability of signal acquisition. At the same time, the module has good electrical protection performance, which can resist surge voltage and electromagnetic interference in industrial sites. Combined with reasonable wiring design, it can further enhance the system's anti-interference ability.
5. Intuitive state monitoring and convenient maintenance
The module is equipped with independent LED status indicator lights, and each input point corresponds to a dedicated indicator light. When the input signal is valid (On), the indicator light lights up, which can intuitively judge the working status of each channel and facilitate on-site troubleshooting. The module uses two 40 pin connectors as external interfaces, with clear and standardized wiring. At the same time, the module weighs only 160g and is compact in size, making it easy to install and maintain in the rack.

Compatible CPU models include F3SP22, F3SP28, F3SP38, F3SP5 *, F3SP6 *, F3SP7 *, etc. (models with * are derived from the series). When configuring the system, the following points should be noted:
-Master and slave configuration: A single master can connect 64 remote I/O stations, remote device stations, or local stations, and must strictly follow the system expansion specifications of the CPU module
-Power timing requirements: When powered on, the remote I/O module power must be turned on first, and then the data link must be started; When power is cut off, the data link should be stopped first, and then the module power should be turned off to avoid data loss or module damage
