Yokogawa Electric Corporation F3XD16-3H DC Input Module

The Yokogawa F3XD16-3H DC Input Module is a 16-point high-speed DC input card for the FA-M3 PLC system, designed to receive 24 VDC digital signals from field devices with response times as fast as 10 µs. Each input draws up to 4.7 mA at a rated input voltage of 24 VDC, operates within 20.4–26.4 VDC, and uses photocoupler isolation to protect the controller from field-side transients. Mounting on the FA-M3 base module enables rapid expansion for high-speed manufacturing lines, machine control systems, and process automation, and it is well-suited for monitoring sensors such as proximity switches, encoders, and limit switches. Common replacements include Yokogawa F3XD16-3F, F3XD16-4F, and F3XD32-3F.
