Yokogawa Electric Corporation STB4S-00 Terminal Module

The Yokogawa STB4S-00 Terminal Module (Style S2) is a pressure-clamp terminal block that provides a direct wiring interface between field devices and digital I/O modules in Yokogawa control systems such as CENTUM VP and ProSafe-RS. This single (non-redundant) configuration block allows field signals from switches, relays, and sensors to be connected directly to digital I/O modules, without the need for separate relay boards or signal cables. It comes without a surge absorber (standard type) and is offered in typical 8- or 16-channel configurations. Compatibility includes SDV144, SDV531, and SDV541 digital I/O modules, with mounting designed for panel or rack installation within control systems. Weight is approximately 0.2 kg. Applications span industrial automation environments including oil and gas, LNG, chemical processing, and power generation, where reliable, organized wiring and secure signal transmission are required for distributed control and safety systems.
