It uses fiber optic cable (multi-mode or single-mode) to deliver high-speed, noise-resistant communication over long distances, with typical distances up to ~5 km and up to ~10 km depending on system, and it supports star and chain network topologies for flexible deployments. The 2-channel ESB bus module draws power from the host system (5 VDC or 24 VDC, system dependent) and is designed for rack- or panel-mount installations, with an operating temperature range of approximately -20 to 60–70 °C (config dependent) and an ISA G3 corrosion-resistant coating for demanding industrial environments. Intended for oil \u0026amp; gas, LNG plants, chemical processing, and power generation, it reliably extends distance and preserves signal integrity between safety controllers and remote I\/O nodes in electrically noisy or large-scale installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"YOKOGAWA","offers":[{"title":"New","offer_id":46241942241514,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-001.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/yokogawa-electric-corporation-snt401-53-optical-bus-repeater-module","provider":"GTG Hardware","version":"1.0","type":"link"}
