F3XC08-0N Yokogawa No-Voltage Contact Input Module – 8-Point Transformer-Isolated Input
The Yokogawa F3XC08-0N is an 8-point no-voltage contact input module for Yokogawa FA-M3 and F3 series control systems. It uses transformer isolation for reliable signal separation in electrically noisy plants. Each input point supports independent interrupt setting. The module suits high-density discrete signal acquisition in process and factory automation.

Installation Guide
- Mount the module in a Yokogawa F3 series base unit slot.
- Wire field contacts to the 10-point M3.5 screw terminal block.
- Keep input cables short and away from high-power lines.
- Set response time per channel in the engineering tool.
- Enable interrupts only on points that need fast event capture.
- Confirm 75 mA current draw fits the base unit power budget.
Commissioning and Maintenance
- Check ON/OFF state per point in the monitor window.
- Measure contact resistance during routine shutdowns.
- Replace contacts above 200 Ω to avoid false OFF states.
- Clean terminals only with dry, lint-free tools.
- No calibration is needed for digital contact inputs.
Compatibility
The F3XC08-0N fits Yokogawa F3 series I/O slots and works with FA-M3 style architectures. It accepts standard dry contacts from pushbuttons, relays, limit switches, and auxiliary contacts. The module pairs with Yokogawa power supply and CPU modules of the same series.
Certifications

- 1 x Protective carton with foam inserts
Warranty and Shipping
All modules carry a 12-month warranty. We ship worldwide by FedEx, UPS, and DHL. Orders placed before 15:00 CST usually ship the same day. Tracking numbers arrive by email after dispatch.
Typical Applications
- Pushbutton and selector switch input in control panels
- Relay and auxiliary contact monitoring
- Limit switch and position feedback on machines
- Alarm and interlock contact scanning
- Legacy FA-M3 system expansion and retrofit
Diagnostic Capability
Each point supports independent interrupt setting for fast event detection. The module reports ON/OFF state per channel in the engineering tool. Fast and slow response modes help separate real contact chatter from valid signals. Line monitoring through the CPU helps locate open or stuck contacts.
FAQ
Q: What input signal does this module accept?
A: It accepts dry no-voltage contacts only. Do not apply external voltage to the input terminals.
Q: How many inputs share one common?
A: All 8 inputs share one common point.
Q: Can I set different response times per channel?
A: Yes. Each channel selects 2.0 ms max. or 17 ms.
Q: Is the module isolated from the backplane?
A: Yes. Transformer isolation separates the input side from the internal bus.
Q: Does it support interrupts?
A: Yes. Interrupt setting is available for each input point.
Q: What is the warranty?
A: 12 months from the date of delivery.
