The module supports eight analog input channels with 12‑bit resolution and configurable voltage ranges, including 0–10 V, and bipolar ranges of ±5 V and ±10 V, enabling precise sensing for process signals. The three analog output channels are also 12‑bit, with output ranges that cover 0–10 V and ±10 V, enabling basic control of actuators or analog setpoints. In addition to the analog I\/O, the 6ES5243-1AA11 provides eight digital inputs and eight digital outputs powered at 24 V DC, with standard current ratings around 0.4 A per output. This full configuration variant is commonly described as IP243 analog module for SIMATIC S5, with a weight around 0.46 kg per module. The part is used to interface legacy S5 PLCs with analog sensors and actuators, enabling measurement and control tasks in industrial automation when retrofitting or maintaining older equipment. Typical applications include temperature, pressure, or flow signal acquisition via the eight AI channels, plus setpoint and simple control signaling through the 3 AO and 8 DO lines, all integrated on a single IP243 expansion module.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268495790314,"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-6es5243-1aa11-programmable-logic-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
