It provides manual speed reference input, allowing technicians to set and adjust motor output frequency directly at the drive or remote panel location. The screw terminal connection simplifies field wiring and supports reliable, repeatable signal output. This type of accessory is typically installed by licensed electricians or drive-certified HVAC technicians during drive commissioning or control system upgrades.\u003c\/p\u003e\n\u003cp\u003eThe MT-105B is suited for industrial and commercial applications where a local manual speed reference is required on a VFD panel. Common install scenarios include pump and fan speed control on HVAC air-handling units, cooling towers, and hydronic systems. It mounts as an accessory to compatible ABB drive enclosures or remote operator panels, providing a straightforward analog reference signal to the drive control board.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5K ohm resistance for standard VFD analog speed reference input\u003c\/li\u003e\n  \u003cli\u003eScrew terminal connection for secure, tool-accessible field wiring\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suited for panel-mount drive enclosures\u003c\/li\u003e\n  \u003cli\u003eDesigned for manual speed reference adjustment on adjustable speed drives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style speed reference accessory for compatible ABB variable frequency drives and remote operator panel installations.

De-energize and lock out the drive system completely before making any control terminal connections. Use appropriately sized conductors and verify the drive analog input accepts a 5K ohm potentiometer reference signal before wiring. Do not apply line voltage to the low-voltage analog input terminals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance\u003c\/strong\u003e: 5,000 ohms (5K ohm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Screw terminal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 32050037610\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MT-105B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383870259506,"sku":"MT-105B","price":233.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678044.jpg?v=1782610087","url":"https:\/\/voomisupply.com\/products\/abb-mt-105b-speed-potentiometer-5k-ohm-screw-terminal","provider":"Voomi Supply","version":"1.0","type":"link"}
