Power connects to the DC 8~28V terminals (V+ and V-). Digital Inputs (DI) connect across DI signal terminals and the switch common terminal (GND), supporting dry contact switches, float switches, and NPN open-collector sensors. Digital Outputs (DO) provide heavy-duty 10A 250VAC \/ 30VDC relay contacts with Normally Open (NO), Normally Closed (NC), and Common (COM) terminals to directly drive contactor coils, pump motors, and alarm sirens. High-frequency RF transmission uses an external 50-ohm SMA-K antenna port. Intuitive front-panel LED indicators display DC power status, LINK connection, and real-time DI\/DO channel activation.\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_01_36cc4610-4c11-456b-93c0-322cf8ac2a75.jpg?v=1793343662\" alt=\"Ebyte E860-DTU Series Wiring \u0026amp; Terminal Layout - 2_01.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_02_3e53f5c1-9375-4050-b5bc-a8522d2e0744.jpg?v=1793343662\" alt=\"Ebyte E860-DTU Series Wiring \u0026amp; Terminal Layout - 2_02.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_03_efed112f-f51d-4db0-a12e-57f0361cba73.jpg?v=1793343662\" alt=\"Ebyte E860-DTU Series Wiring \u0026amp; Terminal Layout - 2_03.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding: 0; line-height: 0; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_04_38f4ca4e-d6ef-4e64-a177-4f4cebc8b003.jpg?v=1793343661\" alt=\"Ebyte E860-DTU Series Wiring \u0026amp; Terminal Layout - 2_04.jpg\" style=\"width: 100%; max-width: 100%; display: block; margin: 0 auto;\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"ebyte-text-specs\" style=\"margin-top: 30px;\"\u003e\n\u003ch2\u003ePractical Application Scenarios\u003c\/h2\u003e\n\u003ch3\u003e1. Remote Water Tower Level Interlock \u0026amp; Pump Station Control\u003c\/h3\u003e\n\u003cp\u003eIn municipal water reservoirs, elevated tanks, and agricultural irrigation pump stations, running physical signal cables over mountains or private property is prohibitively expensive. Deploying an E860-DTU transmitter connected to a liquid level float switch allows instantaneous wireless triggering of the pump starter relay up to 10km away at the well pump house, automatically starting or stopping pumps without human intervention.\u003c\/p\u003e\n\u003ch3\u003e2. Industrial Valve Remote Actuation \u0026amp; Emergency Shutdown (ESD)\u003c\/h3\u003e\n\u003cp\u003eIn chemical processing plants, fuel storage tank farms, and long-distance gas pipelines, emergency stop signals and limit switch feedback must bridge long spans without electrical conduit hazards. The E860-DTU transmits deterministic switch telemetry with sub-300ms latency, triggering emergency pneumatic valve closures wirelessly across vast facility grounds.\u003c\/p\u003e\n\u003ch3\u003e3. Factory Overhead Crane \u0026amp; Hoist Wireless Remote Control\u003c\/h3\u003e\n\u003cp\u003eHeavy overhead bridge cranes, metallurgical ladle cars, and material transfer carts operate across high-vibration manufacturing bays where umbilical cables frequently wear out. The E860-DTU provides a reliable LoRa wireless link immune to motor drive VFD interference, synchronizing pendant pushbutton commands directly to motor drive contactors.\u003c\/p\u003e\n\u003ch3\u003e4. Smart Mining Conveyor Belt Tear \u0026amp; Pull-Cord Safety Systems\u003c\/h3\u003e\n\u003cp\u003eBulk material overland conveyor belts spanning several kilometers require emergency pull-cord switches and belt alignment detection. The E860-DTU enables wireless daisy-chained switch reporting back to the central control PLC, halting conveyor drives immediately upon safety interlock trip.\u003c\/p\u003e\n\u003ch2\u003eFAQ Section\u003c\/h2\u003e\n\u003ch3\u003e1. How do I pair two E860-DTU units for point-to-point switch synchronization?\u003c\/h3\u003e\n\u003cp\u003eWith both units powered on, press and hold the STATE\/LINK button for 2 seconds on the Master device to enter pairing mode (the LINK LED will flash). Then press and hold the STATE\/LINK button for 2 seconds on the Slave device. Within a few seconds, both LINK LEDs will turn solid, confirming successful wireless pairing and synchronous I\/O linkage.\u003c\/p\u003e\n\u003ch3\u003e2. Can one transmitter control multiple receiver units (One-to-Many Mode)?\u003c\/h3\u003e\n\u003cp\u003eYes. The E860-DTU series supports flexible one-to-many broadcast and independent channel mapping. A single Master DTU can synchronize its DI status to multiple Slave DTU relay outputs simultaneously across the entire RF coverage area.\u003c\/p\u003e\n\u003ch3\u003e3. What types of input signals are supported by the DI ports?\u003c\/h3\u003e\n\u003cp\u003eThe DI ports natively support passive dry contacts (pushbuttons, mechanical limit switches, reed switches, relay contacts) as well as active NPN open-collector sensor outputs. Connecting the DI terminal to the GND terminal triggers an input state change.\u003c\/p\u003e\n\u003ch3\u003e4. How do I restore the E860-DTU to factory default settings?\u003c\/h3\u003e\n\u003cp\u003ePress and hold the front-panel STATE\/LINK button for more than 6 seconds until the STATE indicator flashes rapidly. The device will reset all RF channels, encryption keys, and address mappings to default factory parameters.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"E860-DTU(1010-400SL22)-S *2","offer_id":48847845523661,"sku":"E860-DTU(1010-400SL22)-S *2","price":37.7,"currency_code":"USD","in_stock":true},{"title":"E860-DTU(1010-400SL30)-S *2","offer_id":48847845556429,"sku":"E860-DTU(1010-400SL30)-S *2","price":45.81,"currency_code":"USD","in_stock":true},{"title":"E860-DTU(2020-400SL22)-S *2","offer_id":48847845589197,"sku":"E860-DTU(2020-400SL22)-S *2","price":41.76,"currency_code":"USD","in_stock":true},{"title":"E860-DTU(2020-400SL30)-S *2","offer_id":48847845621965,"sku":"E860-DTU(2020-400SL30)-S *2","price":49.86,"currency_code":"USD","in_stock":true},{"title":"E860-DTU(1010-900SL22)-S *2","offer_id":48847845654733,"sku":"E860-DTU(1010-900SL22)-S *2","price":37.7,"currency_code":"USD","in_stock":true},{"title":"E860-DTU(1010-900SL30)-S *2","offer_id":48847845687501,"sku":"E860-DTU(1010-900SL30)-S *2","price":45.81,"currency_code":"USD","in_stock":true},{"title":"E860-DTU(2020-900SL22)-S *2","offer_id":48847845720269,"sku":"E860-DTU(2020-900SL22)-S *2","price":41.76,"currency_code":"USD","in_stock":true},{"title":"E860-DTU(2020-900SL30)-S *2","offer_id":48847845753037,"sku":"E860-DTU(2020-900SL30)-S *2","price":49.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/1_6d8ebad7-897d-49a3-876e-a4548f0d65fd.jpg?v=1793343676","url":"https:\/\/ebyteiot.com\/products\/e860-dtu-series-lora-wireless-io-remote-switch-10km-relay","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
