The Yokogawa YCB141 is a system interface / communication / I/O support module used in Yokogawa CENTUM and ProSafe-RS distributed control architectures.
It belongs to Yokogawa’s YCB (Control Bus / System Interface) series, which is typically used for:
- Signal interfacing
- System-to-system communication support
- I/O and controller integration inside cabinets
It is not a standalone control unit, but part of the system infrastructure layer in Yokogawa DCS/SIS systems.
