Yokogawa F3YP28-0P
Product Overview:
The F3YP28-0P is an 8-channel analog input card for the CENTUM VP DCS platform, functionally similar to F3YP22-0P but with extended configuration options and enhanced diagnostics. It accepts 4-20 mA DC (2-wire) signals from field transmitters. The “0P” suffix indicates non-redundant (single) configuration. The “28” variant typically supports additional input range configurations compared to the “22” variant.

- Set correct input range in CS3000 system configuration for each channel
Precautions:
- Do not exceed 25 mA input current — will damage A/D converter
- Verify loop resistance ≤ 600 Ω including transmitter impedance
- Do not connect voltage sources directly to current input terminals
- Calibrate via software only — do not adjust on-card potentiometers
