Intended for closed-loop hydraulic or pneumatic drives, the unit conditions command, sensor, and feedback signals so that proportional outputs can regulate directional or flow-control valves. Combining signal conditioning, loop computation, and safety gating on one DIN-rail device simplifies cabinet wiring and shortens commissioning time in automated machinery.\u003c\/p\u003e\u003cp\u003eElectrical power is supplied by a nominal \u003cstrong\u003e24 V DC\u003c\/strong\u003e source, and consumption stays at \u003cstrong\u003e6 W\u003c\/strong\u003e. The housing clips on a \u003cstrong\u003eDIN EN 50022\/50035 Rail\u003c\/strong\u003e; recessed terminals satisfy the \u003cstrong\u003eIP20\u003c\/strong\u003e protection class. The demand input offers \u003cstrong\u003e100 kΩ\u003c\/strong\u003e impedance, while auxiliary paths include feed-forward at 6 kΩ, a switched command at 10 kΩ, and sensor current feedback across a 100 Ω burden. Separate reference rails provide –10 V and +10 V, each rated 10 mA, for external potentiometers. For monitoring, the board yields a feedback analog output of ±10 V at 1 mA, and all circuits share a common return to reduce noise.\u003c\/p\u003e\u003cp\u003eLogic gating is handled by two threshold-sensitive pins: the enable line asserts when it rises above \u003cstrong\u003e17 V\u003c\/strong\u003e, whereas the disable line forces the output stage inactive once it falls below \u003cstrong\u003e3.5 V\u003c\/strong\u003e. When active, the PID stage sources a control signal of \u003cstrong\u003e±10 V, 5 mA\u003c\/strong\u003e for direct drive of valve coils or external amplifiers; a high-resolution sensor voltage input with \u003cstrong\u003e1 MΩ\u003c\/strong\u003e impedance feeds the internal error computation without affecting transducer accuracy. Together with the feed-forward and switched inputs mentioned earlier, these functions let the installer tailor loop dynamics, apply proportioning offsets, and verify performance through the dedicated ±10 V feedback port while the device remains within its thermal envelope.\u003c\/p\u003e","brand":"Vickers","offers":[{"title":"Refurbished","offer_id":52060780626221,"sku":null,"price":5031.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/eha-pid-201-a-10__d9d211bf-6719-4fac-8673-b2002afe6190.webp?v=1773213315","url":"https:\/\/servosupplier.com\/products\/eha-pid-201-a-10","provider":"Servo Supplier","version":"1.0","type":"link"}
