It uses Amphenol 19-pin connectors on both the Master and Tool sides and is powered by 24 VDC, with pin A described as the first-to-make, last-to-break in the tool-changer interface and recommended for use as ground; the documented wiring shows two RTL sensors wired in series, and the SA14 Master module is designed to operate with NPN sensors in ATI tool-changer configurations. As part of ATI’s 9121 Master Module family, the 9121-SA14-M is referenced in ATI’s tool changer manuals as the master control component for that system, enabling reliable coordination between sensors and control signals during a tool change in ATI robots. The 9121-SA14-M has been discontinued by the manufacturer. As an older generation master module, the 9121-SA14-M is primarily encountered in legacy ATI tool changer installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"ATI","offers":[{"title":"New","offer_id":51660314444078,"sku":null,"price":174.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a39f59e9-5a41-4c4e-88fc-fe359ba8c620.jpg?v=1769536036","url":"https:\/\/plgautomation.com\/products\/ati-technologies-9121-sa14-m-master-control-module","provider":"PLG Automation ","version":"1.0","type":"link"}
