Introduction
The Yokogawa S2BN1D-12030 Base Plate with Disconnecting Terminal is a key hardware foundation module used in Yokogawa N-IO (Networked I/O) systems within CENTUM VP and ProSafe-RS distributed control architectures. It serves as the physical and electrical mounting platform for I/O modules, enabling safe signal distribution, field wiring termination, and system-level communication in high-availability industrial automation environments.
Designed for mission-critical process industries, this base plate integrates disconnecting terminal functionality, allowing individual channel isolation for maintenance, testing, and troubleshooting without disrupting overall system operation.
