Each of its four inputs is galvanically isolated from the backplane and supports a small-signal, linearized measurement range of ±50 mV per channel, enabling precise capture of low-level sensor voltages with improved accuracy thanks to integrated linearization. The module interfaces with ET 100U or ET 200U deployments and connects to the S5 backplane through standard I\/O connectors, making it suitable for processes where voltage signals from sensors or signal sources must be monitored by an S5 controller; the four channels can be independently utilized to monitor multiple sensors simultaneously. As part of Siemens’ AI 464 analog input family for SIMATIC S5, the 6ES5464-8MA21 provides four voltage input channels for expanding analog data acquisition in older automation networks without requiring newer generation hardware, preserving compatibility with older programming environments and maintenance ecosystems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268511879402,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6es5464-8ma21-simatic-s5-io-module-plc-interface","provider":"GTG Hardware","version":"1.0","type":"link"}
