Yokogawa Electric Corporation F3XD64-3F DC Input Module

The Yokogawa F3XD64-3F DC Input Module is a 64-point DC input card for the FA-M3 PLC system, designed to receive and process 24 VDC digital signals from field devices into the control system. The module accepts DC inputs (sink/source) with a rated 24 VDC, operates over 20.4–26.4 VDC, and draws about 4.1 mA per point, with photocoupler isolation for noise immunity in industrial environments. It is built for high-density digital input interfaces and commonly monitors limit switches, proximity sensors, push buttons, and relay contacts across assembly lines, packaging equipment, material handling systems, and process plants. Mounting is on the FA-M3 base module, and external connections are available via connector or terminal block options, making it suitable for expanding automation panels; common replacements include F3XD64-4F, F3XD32-3F, and F3XD16-3F.
