The servo plate assembly includes the mechanical drive plate and associated motor\/gear components that translate electronic signals into pen motion on the chart chart paper. When installed in the recorder, it ensures correct pen positioning, trace timing, and synchronization with the unit’s input channels. The module is typically used when the original servo mechanism is worn, damaged, or causing inaccurate recordings; it affords a plug-in replacement of the recorder’s pen drive system without full unit replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDirect Fit Replacement: Designed specifically for TRULINE\/DR45AT\/DR4500 series circular chart recorders to ensure compatibility.\u003c\/li\u003e\n\u003cli\u003eServo-Plate Mechanism: Replaces worn or malfunctioning pen drive components--motor, gear, plate--for accurate chart control.\u003c\/li\u003e\n\u003cli\u003eSupport for One or Two Pens: Suitable for single-pen or dual-pen models of the chart recorder family.\u003c\/li\u003e\n\u003cli\u003eHigh-Precision Motion Control: Maintains chart timing, pen alignment and drive stability for accurate process data logging.\u003c\/li\u003e\n\u003cli\u003eSimplified Service Installation: Enables field-replacement of the drive assembly without full recorder removal or re-calibration of inputs.\u003c\/li\u003e\n\u003cli\u003eOEM-Grade Quality: Genuine Honeywell part intended to match original recorder performance and durability.\u003c\/li\u003e\n\u003cli\u003eWeight-Efficient Design: At approximately 1.11 lbs, the module adds minimal load or dimensional change inside the recorder housing.\u003c\/li\u003e\n\u003cli\u003eSurplus Availability: While the original recorder series is older, this part remains stocked by industrial parts suppliers for legacy system maintenance.\u003c\/li\u003e\n\u003cli\u003eReduced Downtime Solution: Installing the servo plate assembly restores recorder functionality quickly, avoiding full unit replacement costs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 30754975-503 provides the mechanical drive foundation required for accurate, dependable chart recording in continuing operation of legacy TRULINE recorder systems.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":49105121509632,"sku":"30754975-503","price":865.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/320316_32029136.jpg?v=1785540716","url":"https:\/\/alotechparts.com\/products\/30754975-503-honeywell-servo-plate-assembly-for-truline-dr45dr4500-circular-chart-recorder","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
