These line drivers feature a rugged aluminum enclosure small enough to mount on the back panel of VDT units, saving valuable desk and floor space.\u003cbr\u003e\u003cbr\u003eThe LDM30 series is designed for full-duplex, asynchronous operation over two, DC-continuity, non-loaded, twisted-wire pairs. Through special high-speed optically-coupled circuits they may communicate at data rates up to 57,600 baud. A self-powered model and a host-powered model are available. The self-powered unit uses 12VAC from a wall-mounted transformer while the host-powered unit takes ±DC power from pins 9 and 10 of the RS-232 connector. The line driver circuits - and, consequently, the host device - are protected from electrical transients due to lightning strikes or operation of heavy industrial equipment.\u003cbr\u003e\u003cbr\u003eEach device features a convenient Data-Communication Equipment (DCE) to Data-Terminal Equipment (DTE) switch which reverses pins 2 and 3 of the RS-232 connector. For installation and troubleshooting, each unit has diagnostic Light-Emitting Diodes (LEDs) on the transmit and receive lines.\u003cbr\u003e\u003cbr\u003eThe RS-232 connector may be ordered as a male or female 25-pin connector. Field connection is made through a modern, solderless, screw-termination assembly. Alternatively, a convenient four-wire modular phone jack (RJ-11) is available.\u003c\/div\u003e\n\u003cdiv class=\"col-md-3\"\u003e\n\u003cdiv class=\"card bg-primary\"\u003e\n\u003cdiv class=\"card-header\"\u003e\n\u003ch5 class=\"card-title text-white\"\u003eCertifications\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"card-body bg-secondary fs-sm\"\u003e\u003ca href=\"https:\/\/www.dataforth.com\/certifications-compliance\/\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv class=\"card-footer\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"section_features\" class=\"mt-4\"\u003e\n\u003ch3 class=\"mt-9\"\u003eFeatures\u003c\/h3\u003e\n\u003cp class=\"fs-sm\"\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDC to 57,600 Baud\u003c\/li\u003e\n\u003cli\u003eOptical Isolation\u003c\/li\u003e\n\u003cli\u003eSurge Protectors\u003c\/li\u003e\n\u003cli\u003eLED Diagnostic Indicators\u003c\/li\u003e\n\u003cli\u003eOperation to 3 Miles (5km) at 9600 Baud, 1 Mile (1.7km) at 19,200, 0.5 Miles (0.8km) at 57,600\u003c\/li\u003e\n\u003cli\u003eFour-Wire Full Duplex, Two-Wire Simplex\u003c\/li\u003e\n\u003cli\u003eSelf-Powered or Host-Powered\u003c\/li\u003e\n\u003cli\u003eSelection of Connectors\u003c\/li\u003e\n\u003cli\u003eWide Operating Temperature Range, 0 to +70°C\u003c\/li\u003e\n\u003cli\u003eCE Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"section_blockdiagram\" class=\"mt-4\"\u003e\n\u003ch3\u003eBlock Diagram\u003c\/h3\u003e\n\u003cimg src=\"https:\/\/www.dataforth.com\/media\/blockdiagram-images\/ldm\/ldm30logic.png\" alt=\"\"\u003e\n\u003c\/div\u003e","brand":"Outlecta.com","offers":[{"title":"Default Title","offer_id":53753168363857,"sku":null,"price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/9522\/8753\/files\/IMG-3395.png?v=1778575487","url":"https:\/\/www.outlecta.com\/products\/dataforth-ldm30-general-purpose-rs-232-line-driver","provider":"Outlecta.com","version":"1.0","type":"link"}
