This compact module, weighing \u003cstrong\u003e0.17 kg\u003c\/strong\u003e, operates on a nominal \u003cstrong\u003e+24 V DC (Tolerance: +40% \/ −5%)\u003c\/strong\u003e supply and accepts input signals for dual-channel control. Featuring robust connectivity via a \u003cstrong\u003e32-pole male multipoint connector, DIN 41612 Design D\u003c\/strong\u003e, the VT-VSPA 1-1-12 ensures secure and standardized interfacing within Eurocard-based control cabinets. Its zero adjustment range of \u003cstrong\u003e±30%\u003c\/strong\u003e and ramp time settings from \u003cstrong\u003e20 ms to 5 s\u003c\/strong\u003e provide fine-tuned response shaping to minimize hydraulic shock.\u003c\/p\u003e\n\n\u003cp\u003eIn terms of detailed specifications, the amplifier adheres to a \u003cstrong\u003eEuro-card, 100 mm x 160 mm, DIN 41494\u003c\/strong\u003e form factor for seamless integration. The first control channel supports a \u003cstrong\u003esingle-ended input of 0 to +9 V referenced to M0\u003c\/strong\u003e, while the second channel provides a \u003cstrong\u003edifferential input selectable among 0–10 V, 0–20 mA, and 4–20 mA\u003c\/strong\u003e via integrated DIL switches. A \u003cstrong\u003e2.5 A slow-blow fuse\u003c\/strong\u003e protects the unit against overload, while peak current consumption peaks at \u003cstrong\u003e1.8 A\u003c\/strong\u003e and overall power consumption remains below \u003cstrong\u003e50 VA\u003c\/strong\u003e. The regulated voltage output of \u003cstrong\u003e±9 V with ±1% accuracy\u003c\/strong\u003e drives solenoids with selectable current outputs of \u003cstrong\u003e800 mA or 1600 mA\u003c\/strong\u003e. Additionally, the amplifier supports \u003cstrong\u003eclock frequencies of 100 Hz or 160 Hz\u003c\/strong\u003e for high-fidelity current modulation.\u003c\/p\u003e\n\n\u003cp\u003eOperationally, the VT-VSPA 1-1-12 functions reliably across an \u003cstrong\u003eambient temperature range of 0 to +50 °C\u003c\/strong\u003e, making it suitable for indoor factory environments. Ramp time adjustment between \u003cstrong\u003e30 ms and approximately 1 s, with an optional 5 s setting\u003c\/strong\u003e, enables smooth actuation profiles and reduces wear on hydraulic components. The module’s power supply voltage range extends from \u003cstrong\u003e18 V to 35 V\u003c\/strong\u003e, accommodating moderate fluctuations common in industrial DC bus systems. With a compact mass and standardized connector configuration, the amplifier delivers consistent performance under continuous duty cycles.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for system integrators, the VT-VSPA 1-1-12 interfaces directly with Bosch Rexroth hydraulic valves and PLC-based control architectures. Its DIN-rail compatible Euro-card format simplifies retrofitting into existing racks or new panel builds. Ideal for applications in mobile hydraulics, manufacturing automation, and process control, this amplifier balances precision, robustness, and ease of integration. It is particularly well suited to valve control tasks in assembly lines, injection molding machines, and test stands requiring reliable proportional control.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unused Surplus","offer_id":52029988012333,"sku":null,"price":3049.72,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52103121895725,"sku":null,"price":2772.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/VT-VSPA_Series__95df84f6-48e4-48fa-aefa-2dad7d912d23.webp?v=1760641933","url":"https:\/\/servosupplier.com\/products\/vt-vspa-1-1-12","provider":"Servo Supplier","version":"1.0","type":"link"}
