It provides 1 analog input channel for thermocouples (types J, K, T, E, R\/S, B, N, C, TXK\/XK(L)) and is used to capture precise temperature readings within automation projects. The module is powered from the backplane with a 24 V DC supply, drawing about 5 mA; backplane bus provides 5 V DC (typical) with up to 20 mA, and a typical power loss of 0.5 W. The analog input accepts thermocouple signals with an input range up to ±80 mV and a destruction-limit input voltage of ±35 V for current or voltage inputs; input resistance for the thermocouple range is ≥1 MΩ. Temperature measurement units are configurable in degrees Celsius or Fahrenheit. As part of the SIMATIC S7-1200 signal-board family, this expansion is intended for temperature sensing in industrial processes, HVAC, and equipment monitoring where a compact, single-channel thermocouple input is integrated alongside the PLC backplane.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268580856042,"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-6es7231-5qa30-0xb0-programmable-logic-controller-cpu-module","provider":"GTG Hardware","version":"1.0","type":"link"}
