Field Wiring Termination Interface for Yokogawa DCS Systems
The Yokogawa YCB311-M070 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 organization, and support efficient installation, testing, and maintenance in process automation environments.
The YCB311 series terminal interface modules are passive connection assemblies. They provide field wiring termination and signal routing between plant devices and Yokogawa I/O hardware; signal acquisition, conversion, and control functions are performed by the associated Yokogawa I/O modules. Yokogawa control systems use dedicated interface and terminal assemblies to organize connections between I/O modules and field wiring.
