Yokogawa Electric Corporation STB4S-00S2 Terminal Module

The Yokogawa Electric Corporation STB4S-00S2 Terminal Module, Style S2, is a pressure clamp terminal block that directly wires field devices to Yokogawa digital I/O modules, eliminating the need for intermediate interface boards and improving wiring reliability. This is a single (non-redundant) configuration without a surge absorber, designed for standard industrial applications. The module supports typically 8 or 16 channels, uses pressure clamp direct wiring, and is compatible with SDV144, SDV531, and SDV541 digital I/O modules, weighing approximately 0.2 kg and intended to be installed inside a control panel or I/O rack. Common applications include interfacing field devices such as switches, relays, and sensors in oil and gas, LNG plants, chemical processing, and power generation where reliable terminations and organized panel wiring are required.
