The unit’s signal inputs—PULSE, DIR, GATE\/ENABLE, ZERO CURRENT, and MICROSTEP—are optically isolated and protected against reverse polarity, with logic high between 2.5 and 5.25 V, input currents up to 20 mA, and an input frequency rating up to 200 kHz; it also features DIP switches for setting the number of steps per revolution, motor current reduction, and microstep options. Exterior dimensions are 100 × 160 × 51 mm and it weighs about 0.15 kg; power is drawn from 18–40 VDC with a maximum declared power loss around 20 W, and motor connections accommodate 3×24 V coils with adjustable per‑phase current from roughly 1.45 to 5.8 A. The D920.51 includes a hook switch for microstep selection and aligns with Berger Lahr’s 19\" rack‑mount (3HU) housing options, with typical installation support for up to 5 m twisted supply cables and an operating environment of 0 to +50 °C, 5–85% relative humidity (no condensation), and pollution degree 2; the model is cataloged under order number 0062010920513. \u003c\/p\u003e\u003c\/div\u003e","brand":"Berger","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676930113838,"sku":null,"price":217.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_0a248766-ba06-498d-8e28-c94238019f67.jpg?v=1769555378","url":"https:\/\/plgautomation.com\/products\/berger-lahr-d920-51-circuit-board-drive-module","provider":"PLG Automation ","version":"1.0","type":"link"}
