{"product_id":"b-b-electronics-4wsd9otb-isolated-dc-converter","title":"B\u0026B Electronics 4WSD9OTB Isolated DC Converter","description":"\u003cdiv\u003e\u003cp\u003eBB-4WSD9OTB is an isolated RS-232 to RS-422\/RS-485 in-line converter that provides up to 2 kV isolation between the RS-232 input and the RS-422\/RS-485 output. It is DC-powered (10–48 VDC) via a 2‑position terminal block and typically draws about 28 mA at 12 VDC. The RS-232 side uses a female DB9 connector (DB9F), while the RS-422\/RS-485 signals are delivered over a 5‑position data terminal block. Its compact footprint measures roughly 3.9 x 1.7 x 0.9 inches (9.8 x 4.3 x 2.3 cm), and it operates from 0 to 70°C (32–158°F). The unit carries CE approvals and is designed to bridge legacy RS-232 devices to differential serial networks, enabling reliable long-distance or electrically noisy installations without compromising equipment safety. \u003c\/p\u003e\u003c\/div\u003e","brand":"B\u0026B","offers":[{"title":"New","offer_id":51660451381550,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6be646e4-3adc-435d-8fcb-2eb8562d8b0c.jpg?v=1769537752","url":"https:\/\/plgautomation.com\/products\/b-b-electronics-4wsd9otb-isolated-dc-converter","provider":"PLG Automation ","version":"1.0","type":"link"}
