It is intended to shape command signals for proportional valve coils or other motion-control devices, providing a controlled voltage or current ramp that prevents sudden changes in actuator speed and reduces hydraulic shock within automated machinery.\u003c\/p\u003e\u003cp\u003eThe module can source up to \u003cstrong\u003e10 mA\u003c\/strong\u003e from its auxiliary +10 V reference, allowing potentiometer or sensor excitation without an external supply. Its differential input presents \u003cstrong\u003e100 kΩ\u003c\/strong\u003e of impedance, minimizing loading on upstream controllers, and the accepted command span is \u003cstrong\u003e±10 V\u003c\/strong\u003e, matching most industrial analog outputs. Internal electronics draw a maximum of \u003cstrong\u003e6 W\u003c\/strong\u003e, a value useful for cabinet cooling calculations. When the enable line falls below the disable threshold of \u003cstrong\u003e3.5 V\u003c\/strong\u003e, ramp generation is blocked, ensuring predictable shutdown behavior. For very fast sequences the front-panel potentiometer can be set to a minimum ramp interval of \u003cstrong\u003e50 ms\u003c\/strong\u003e, allowing quick transitions while still limiting inrush current to the valve coil.\u003c\/p\u003e\u003cp\u003eThe power terminals accept up to \u003cstrong\u003e36 VDC\u003c\/strong\u003e and remain functional down to \u003cstrong\u003e18 VDC\u003c\/strong\u003e, giving flexibility when the control system shares a supply with other loads. Allowed ambient temperature extends to \u003cstrong\u003e50 °C\u003c\/strong\u003e, so the card can be mounted in warm enclosures provided airflow is adequate. The enable circuit recognizes external logic between 12 VDC and 40 VDC, letting a PLC or relay gate the ramp output without extra converters. Output capability reaches 5 mA across a ±10 V swing, and the ramp duration can be stretched to 5 s for gentle acceleration profiles. A differential input format improves noise rejection, maintaining an accurate command even when long shielded cables are used on the factory floor.\u003c\/p\u003e","brand":"Vickers","offers":[{"title":"Unused Surplus","offer_id":52063552635181,"sku":null,"price":8030.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/eha-rmp-201-a-20__26f4f4af-eb16-4883-a361-f1efb6c7ca1f.webp?v=1773213311","url":"https:\/\/servosupplier.com\/products\/eha-rmp-201-a-20","provider":"Servo Supplier","version":"1.0","type":"link"}
