{"product_id":"eha-pid-201-a-20","title":"EHA-PID-201-A-20","description":"\u003cp\u003eThe \u003cstrong\u003eEHA-PID-201-A-20\u003c\/strong\u003e module is a regulated DC power supply and signal conditioner manufactured by Vickers within the EHA Power Supplies series. It furnishes the low-level voltages and references needed for closed-loop motion hardware, while accepting command and feedback signals that coordinate proportional valves and other actuators in automated equipment.\u003c\/p\u003e\u003cp\u003eNominal operation requires a supply of \u003cstrong\u003e24 VDC\u003c\/strong\u003e, and at this input the unit draws only \u003cstrong\u003e6 W\u003c\/strong\u003e, minimizing panel heat. Command data enter through a differential demand port that accepts \u003cstrong\u003e±10 V\u003c\/strong\u003e and presents a high impedance of \u003cstrong\u003e100 kΩ\u003c\/strong\u003e, so upstream controllers are not loaded. A separate feed-forward channel also spans ±10 V but offers a lower impedance of \u003cstrong\u003e6 kΩ\u003c\/strong\u003e to improve noise immunity over short cable runs. Sensor feedback is handled either as a ±10 V voltage input with 1 MΩ impedance or as a current signal observed across a 100 Ω burden resistor. Positive and negative reference outputs deliver +10 V and –10 V at 10 mA each, providing stable excitation for potentiometers and displacement transducers.\u003c\/p\u003e\u003cp\u003eClosed-loop drive signals leave the card through the PID stage, which can swing from \u003cstrong\u003e±10 V\u003c\/strong\u003e while sourcing up to \u003cstrong\u003e5 mA\u003c\/strong\u003e for direct valve modulation. Output accuracy is maintained by internal regulation that keeps residual ripple within \u003cstrong\u003e±10% pk\u003c\/strong\u003e of the commanded value. The electronics sit inside an enclosure rated \u003cstrong\u003eIP20\u003c\/strong\u003e under IEC 529, indicating finger-safe construction for mounting inside a protected cabinet. With isolated reference rails and a dedicated 5 mA PID channel, the module links seamlessly to external amplifiers, ensuring deterministic control without the need for auxiliary buffering.\u003c\/p\u003e","brand":"Vickers","offers":[{"title":"Unused Surplus","offer_id":51909353636141,"sku":null,"price":11402.12,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52056143102253,"sku":null,"price":10365.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/eha-pid-201-a-20__f274c621-6823-469c-a556-e4a7255f03ac.webp?v=1773213313","url":"https:\/\/servosupplier.com\/products\/eha-pid-201-a-20","provider":"Servo Supplier","version":"1.0","type":"link"}
