Yokogawa STB4S-00 Terminal Module

The Yokogawa STB4S-00 Terminal Module is a pressure clamp terminal block designed for direct wiring of digital input and output signals in Yokogawa control systems such as CENTUM VP and ProSafe-RS. Configured as a single (non-redundant) terminal block, it supports typically 8 or 16 channels and uses pressure clamp direct wiring to connect field devices, eliminating the need for intermediate relay boards or signal cables. Surge absorber is not included (standard type); weight is approximately 0.2 kg, and the unit mounts inside control panels or I/O racks. It interfaces with SDV144, SDV531, and SDV541 digital I/O modules, providing a reliable signal termination between field wiring and I/O modules for industrial automation in oil and gas, LNG, chemical processing, and power generation.
