Description
The Yokogawa F3WD64-3N is a high-density combined digital input and transistor output module engineered for the FA-M3 programmable logic controller (PLC) platform. It handles mixed discrete automation tasks within a single slot, processing incoming binary field states while simultaneously driving local control actuators like indicators, solenoids, and interposing relays.

Engineering Integration Notes
The F3WD64-3N combines 32 inputs and 32 outputs into a single module slot, making it efficient for compact control enclosures where cabinet footprint is restricted. When wiring this card, ensure that the external 24 V DC power supply feeding the transistor output commons is adequately sized and fused to handle aggregate load spikes.
Because the module uses high-density 40-pin flat cable connectors, channel mapping between the physical connector pins and the software I/O allocation must be verified against Yokogawa pinout documentation during pre-commissioning checkouts. Separate input signal wiring from output power paths to minimize crosstalk and induced electrical noise.
Frequently Asked Questions
Q: How are the input and output channels separated on the 40-pin connector?
A: The 40-pin connector breaks out both the 32 input points and 32 output points across shared or multi-row pin definitions. Review the specific Yokogawa FA-M3 hardware manual wiring diagram to match your pre-fabricated cable breakout blocks.
Q: Can the transistor outputs drive inductive loads directly?
A: The outputs feature built-in Zener diode surge suppression for minor inductive kickback, but heavy inductive loads (such as large contactors or magnetic valves) require external freewheeling diodes or interposing relays to extend transistor lifespan.
Q: Does this module require an external power supply for the inputs?
A: Yes, inputs require an external 24 V DC power source to supply wetting current to the dry contacts or sinking field sensors connected to the system.
