It features a USB connector on one end and an 8-pin DIN connector on the other, with a total length of 3.05 m (USB cable 0.61 m, DH+ cable 2.44 m). It supports three DH+ communication rates: 57.6 kbps (maximum network length 3048 m), 115.2 kbps (1524 m), and 230.4 kbps (762 m). The device includes a 3-position switch for node address configuration and LED indicators for USB status, power, and DH+ network activity. It draws power from the USB port, consuming 125 mA at 5 VDC (1.575 W dissipation), with isolation voltage of 30 V. The adapter is enclosed in an IP30-rated housing and is designed for operation in environments from 0 to 55 °C. Typical applications include connecting programming workstations to PLC-5 processors (except classic PLC-5\/10, 5\/12, 5\/15, and 5\/25) and SLC 5\/04 controllers, replacing older PCMCIA-based solutions such as the 1784-PCMK with PCM6 cables.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesign: Portable USB-to-DH+ communication adapter.\u003c\/li\u003e\n\u003cli\u003eCompatibility: Supports PLC-5 (except classic models) and SLC 5\/04 controllers.\u003c\/li\u003e\n\u003cli\u003eConnectors: USB interface to PC; 8-pin DIN connector for DH+ network.\u003c\/li\u003e\n\u003cli\u003eCable Length: 3.05 m total (0.61 m USB, 2.44 m DH+).\u003c\/li\u003e\n\u003cli\u003eProtocols: Data Highway Plus (DH+) using RS-485 convention.\u003c\/li\u003e\n\u003cli\u003eData Rates: 57.6 kbps (3048 m), 115.2 kbps (1524 m), 230.4 kbps (762 m).\u003c\/li\u003e\n\u003cli\u003ePower Supply: 5 VDC from USB port, 125 mA current draw, 1.575 W dissipation.\u003c\/li\u003e\n\u003cli\u003eIndicators: LED status for USB, power, and DH+ network activity.\u003c\/li\u003e\n\u003cli\u003eHousing: IP30-rated enclosure, portable design.\u003c\/li\u003e\n\u003cli\u003eEnvironmental Ratings: Operating 0…55 °C, storage –40…85 °C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 1784-U2DHP provides a reliable and portable interface for connecting modern computers to legacy DH+ networks, ensuring continued productivity in systems using PLC-5 and SLC controllers.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":47158801596714,"sku":"1784-U2DHP","price":2999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/shopping_5_2e2d0821-076f-4e84-9757-ee43e6ac23eb.webp?v=1721127213","url":"https:\/\/iqelectro.com\/products\/allen-bradley-1784-u2dhp-usb-to-data-highway-plus-programming-adapter-with-2-44-m-cable","provider":"IQElectro","version":"1.0","type":"link"}
