Each channel supports standard thermocouple types B, E, J, K, L, N, R, S, and T, with a 16-bit conversion result and an internal 24-bit resolution achieved through Sigma-Delta processing. The inputs are galvanically isolated from the backplane to protect the controller and minimize ground-loop interference. The module provides an eight-channel thermocouple input solution with a 50 ms conversion time, suited for responsive temperature monitoring in process control environments. It uses a 40-pin front connector and is designed to mount in a SIMATIC S7-300 rack, integrating seamlessly with Siemens PLC architectures for temperature measurement, furnace control, plastics processing, and other applications requiring multiple thermocouple types in a single device.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268587475178,"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-6es7-331-7pf11-0ab0-programmable-logic-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
