YOKOGAWA SBD2D-06 STYLE S2 TERMINAL BOARD

Description:

The Yokogawa SBD2D-06 (Style S2) Terminal Board is used a DIN rail–mounted digital output interface board used in Yokogawa ProSafe-RS and CENTUM systems. It serves as the wiring interface between digital output modules (such as SDV521) and field devices, providing organized signal routing and protection. The board is a passive component—no signal processing designed for reliable field wiring and system integration. 

Applications:

The Yokogawa SBD2D-06 is used in industrial environments to connect digital output modules to field devices such as relays, actuators, and control circuits. It is commonly deployed in safety instrumented systems (SIS), chemical processing, power generation, and manufacturing. The board ensures structured wiring, safe signal distribution, and compatibility with Yokogawa’s FIO/ESB architecture.
