The board regulates internal power distribution to handle thermal heat sink dissipation profiles generated during high-load bipolar operations up to +\/-250 mA. The internal digital processing architecture converts input demands via an 11-bit high-definition positioning matrix, eliminating calibration drift linked to component aging, and matches the driving profiles required by the Woodward 512 and 8256 series proportional actuators.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the 8200-226 module handle a sudden short-circuit condition within the external actuator coils?\u003c\/p\u003e\n\u003cp\u003eA: The module relies on integrated hardware protection circuitry that immediately clamps the output loop to prevent damage, while concurrently registering a diagnostic fault signal back to the main electronic governor.\u003c\/p\u003e\n\u003cp\u003eQ: Is the bipolar output current fixed, or can it be adjusted for smaller servo valves?\u003c\/p\u003e\n\u003cp\u003eA: The output current is software configurable from +\/-10 mA up to +\/-250 mA, allowing engineers to calibrate the driver output to match the precise electrical parameters of the target actuator.\u003c\/p\u003e\n\u003cp\u003eQ: What legacy Woodward modules does the 8200-226 directly replace?\u003c\/p\u003e\n\u003cp\u003eA: This model serves as the official digital upgrade path for the legacy analog 8200-224 and 8200-225 driver boards.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the 8200-226 assembly securely inside the control enclosure, ensuring proper clearance around the integrated thermal heat sink structures to support unimpeded air dissipation. Before connecting the 18-32 VDC primary input power, verify that the power supply polarity matches the driver terminal block layout. Connect all analog demand signals (such as 4-20 mA or 1-5 VDC) and bipolar actuator drive loops using individual shielded twisted-pair cables. Terminate the shield drain wires at the designated enclosure chassis ground rail to prevent stray electromagnetic interference from degrading the 11-bit control resolution.\u003c\/p\u003e","brand":"Woodward","offers":[{"title":"Default Title","offer_id":42870860742746,"sku":"8200-226","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/167._7c2cd212-08d3-4b7b-9674-6b1c76b1281d.jpg?v=1772507977","url":"https:\/\/www.spareoil.com\/products\/8200-226-woodward-bipolar-actuator-driver-24vdc-250ma","provider":"SpareOil Automation","version":"1.0","type":"link"}
