Multi-Point Field Termination Assembly for Yokogawa Control Systems
The Yokogawa YCB147-2 Terminal Block Assembly is an industrial field wiring termination component designed to provide a reliable interface between Yokogawa I/O modules and plant field instrumentation. It is used to organize field cables, simplify control cabinet wiring, and improve maintenance efficiency in process automation systems.
The YCB147-2 is a passive terminal block assembly. It does not perform signal processing or control functions; instead, it provides structured electrical termination and routing for instrumentation signals connected to Yokogawa automation systems.
