The analog input enables the recording and processing of four analog input signals. These are e.g. 0-1 V, 0-5 V, 0-10 V, 1-10 V, 0-20 mA, 4-20 mA, 0-1000 Ohm, PT100, PT1000 and potential-free contact. A power supply unit for supplying the sensors with 24 V DC voltage is integrated. The device can be operated with 115 to 230 V AC, 50/60 Hz. A maximum of 300 mA is available across the entire voltage range. The application software is tailored to the recording of analog values.
