Implementation of 4-20 mA HART loop protocol translation is managed via the DCS application logic. Electrical isolation is maintained through the backplane connection to the Node Unit (ANB10\/ANB11\/ANR10), ensuring that transient voltages on the serial lines do not propagate to the FCS processor.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the ALR111-S00 hot-swappable?\u003c\/p\u003e\n\u003cp\u003eA: Yes. When installed in a dual-redundant configuration with a paired module in an adjacent slot, the unit supports online replacement without interrupting the control process.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum cable distance for RS-232C connections?\u003c\/p\u003e\n\u003cp\u003eA: The maximum transmission distance is 15 meters per port. Exceeding this limit may result in signal degradation due to RS-232C voltage level attenuation.\u003c\/p\u003e\n\u003cp\u003eQ: Can this module be used for multipoint networks?\u003c\/p\u003e\n\u003cp\u003eA: No. The ALR111-S00 is strictly limited to point-to-point RS-232C connections. For multipoint configurations, the ALR121 (RS-422\/RS-485) model must be used.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the module into the designated slot of the Node Unit (ANB10, ANB11, ANR10, F50, AFV10, FV30, or AFV40). Use approved I\/O wiring components including AKB131, AKB132, AKB133, AKB134, or 3-pair shielded cable (AKB161\/AKB162). Ensure the shield drain wire is terminated at the DCS cabinet ground bus bar only, maintaining a single-point ground to mitigate EMI. Verify that the backplane power supply has sufficient current margin for the 0.5 A consumption of the module before energizing the system.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44209085284440,"sku":"ALR111-S00","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/ALR111-S00-3.jpg?v=1780975866","url":"https:\/\/www.industriaxplc.com\/products\/serial-communication-module-yokogawa-alr111-s00","provider":"IndustriaX Limited","version":"1.0","type":"link"}
