F3XC08-0C Yokogawa No-voltage Contact Input Module – 8 Point, Separate Commons
The Yokogawa F3XC08-0C is an 8-point no-voltage contact input module for Yokogawa F3 series I/O systems. It uses transformer isolation. Each input has a separate common. This suits discrete signal acquisition in industrial control panels.
The module accepts dry contact signals. It supports a wide contact rating window. Input sampling time is selectable in 5 steps. Interrupts can be set for each input point. The 18-point M3.5 screw terminal block simplifies field wiring.
Core benefit: fast response, point-level interrupt, and channel-to-channel isolation for mixed-signal panels. Call or WhatsApp +86 158 8020 0923 for stock and lead time. Email info@oiltechcontrols.com.

Key Performance Data
- Resolution: 1 bit per input point, 8 points total.
- Response window: sampling period plus 1 ms max. Fastest setting is 0 μs.
- Input margin: ON resistance 200 Ω max. OFF resistance 100 kΩ min.
- Temperature range: 0 to 55 °C operating. -20 to 75 °C storage.
- Environmental tolerance: 10 to 90% RH. Keep panel air free of corrosive gas and heavy dust.
- Noise immunity: transformer isolation blocks ground loops between channels.
- Channel density: 8 inputs with separate commons. All points may be ON at once.
Installation Guide
- Mount the module in a Yokogawa F3 series rack or base unit.
- Wire dry contacts to the 18-point M3.5 screw terminal block.
- Keep input leads short. Route them away from motor and drive cables.
- Confirm contact resistance is below 200 Ω when closed.
- Check open contact resistance is above 100 kΩ.
- Set sampling time per channel in the engineering tool.
- Enable per-point interrupt only where fast events need capture.
- Verify 75 mA current draw against the rack power budget.
Commissioning and Maintenance
Commissioning is simple. Force each input in the engineering tool. Watch the status bit change. Then test with a real contact closure. For maintenance, check terminal screw torque at each service interval. Clean dust from the terminal block. Re-seat the module if a channel reads false. No calibration is needed for contact inputs.
Compatibility Notes
The F3XC08-0C fits Yokogawa F3 series I/O racks. It works with standard dry contact devices. Examples include pushbuttons, limit switches, relay contacts, and selector switches. It suits mixed-signal panels that need separate commons. Confirm rack slot and power budget before you order. Contact +86 158 8020 0923 on WhatsApp for a compatibility check.
Certification and Quality
Units ship as original Yokogawa industrial surplus or refurbished stock. We test every module before dispatch. Test report and warranty terms ship with the order. Ask us for available documentation on your PO.
Packing List and Warranty
- 1 x Yokogawa F3XC08-0C module
- 1 x test report
- 1 x protective packing
- 12-month warranty on function
