It uses a green vacuum fluorescent display with 20 characters per line and supports 2-line (2124) or 4-line (2125) configurations, with an optional 128K memory to store messages or programs. The enclosure measures about 6.85 inches wide, 7.70 inches high, and 3.67 inches deep and weighs roughly 2 lb, and it offers Port A for internal fixed parameters, Port B for PLC communications (RS‑232, RS‑422, RS‑485 or current loop) at common baud rates up to 19.2K, plus an auxiliary Port X for additional serial connections. Mounting hardware and panel-sealing options provide indoor use with Type 4X protection, operating temperature 0–50 C, storage -20 to 60 C, humidity 10–95% non-condensing, and UL\/CUL approvals. In catalog ecosystems, the 128‑D designation is commonly paired with 128K memory options and four-line displays, reflecting its status as a legacy operator interface that many suppliers list as discontinued by the manufacturer.\u003c\/p\u003e\u003c\/div\u003e","brand":"CINCINNATI","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678062903598,"sku":null,"price":51.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d03758a8-1229-4d30-84b8-4e4b7762fc19.jpg?v=1769571254","url":"https:\/\/plgautomation.com\/products\/greyline-cincinnati-electrosystems-operator-panel-128-d-operator-panel","provider":"PLG Automation ","version":"1.0","type":"link"}
