Compact Field Wiring Interface for Yokogawa DCS Systems
The Yokogawa YCB311-M080 Terminal Interface Module is an industrial terminal interface assembly designed to provide an organized connection point between field instrumentation wiring and Yokogawa distributed control system (DCS) I/O modules. It is used to simplify cabinet wiring, improve signal routing, and support easier commissioning and maintenance in process automation environments.
The YCB311 series terminal interface modules are used as structured wiring interfaces in Yokogawa control system installations. They provide the physical connection between field cables and I/O equipment, while signal acquisition and processing are performed by the connected Yokogawa I/O modules. Yokogawa DCS connection documentation identifies terminal boards/interfaces as components used for connecting I/O modules and field wiring through dedicated connection methods.
