The module manages DH+ communication timing and data exchange between USB-connected computers and PLC-5 or SLC 5\/04 controllers. Communication speed selection is dependent on network distance and DH+ physical layer conditions.\u003c\/p\u003e\n\u003cp\u003eThe module supports PLC programming and configuration operations through compatible Allen-Bradley software environments. The interface hardware provides status indication through integrated LED diagnostics for USB power availability and DH+ network communication activity.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What controller families can be connected through the 1784-U2DHP?\u003cbr\u003eA: The module supports PLC-5 processors except Classic PLC-5 models including PLC-5\/10, PLC-5\/12, PLC-5\/15, and PLC-5\/25. It also supports SLC 5\/04 processors.\u003c\/p\u003e\n\u003cp\u003eQ: What is the power requirement of the 1784-U2DHP?\u003cbr\u003eA: The module operates from a 5.00 VDC to 5.25 VDC supply and has a maximum power dissipation of 1.575 W.\u003c\/p\u003e\n\u003cp\u003eQ: How does DH+ communication speed vary with network distance?\u003cbr\u003eA: The module supports 230.4 Kbps at shorter distances up to 762 m, 115.2 Kbps up to 1524 m, and 57.6 Kbps up to 3048 m.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 1784-U2DHP on a workstation side connection point with the USB cable connected directly to the programming computer and the DH+ interface connected to the network segment.\u003c\/p\u003e\n\u003cp\u003eRoute DH+ communication wiring separately from high-voltage power cables, motor leads, and high-frequency switching conductors to reduce electrical interference. Maintain proper cable shielding practices according to the DH+ network installation requirements. Verify connector seating, network termination conditions, and communication status LEDs before commissioning.\u003c\/p\u003e\n\u003cp\u003eAvoid installing the communication module in locations exceeding the specified operating temperature range or enclosure protection limitations. Confirm compatible controller firmware and programming software support before establishing PLC communication.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43737617793114,"sku":"1784-U2DHP","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1784-U2DHP2.jpg?v=1785132169","url":"https:\/\/www.plcmasters.com\/products\/1784-u2dhp-allen-bradley-data-highway-plus-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
