The module can sample and convert input signals at a rate of 1,000 times per second, making it suitable for processes requiring faster data updates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the AMM22 compatible with CENTUM VP?\u003c\/strong\u003eA: Yes, the AMM22 is designed for use in both CENTUM CS and the newer CENTUM VP systems, providing a reliable migration path for control system upgrades.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this module for 4-20 mA inputs?\u003c\/strong\u003eA: While the standard output signal is listed as 4-20 mA DC (referring to the internal bus communication or converted signal), the AMM22 is primarily an input module for low-level signals like mV or Thermocouples. For direct 4-20 mA input, other models like the AMM42 or AAM10 series might be more appropriate depending on the specific application.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":52522726457653,"sku":"AMM22","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/AMM22.jpg?v=1775033396","url":"https:\/\/www.5gplc.com\/products\/amm22-yokogawa-multiplexer-input-module-for-centum-systems","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
