The analogue input is used to detect and process 4 independent input signals. E.g. 0-1 V, 0-5 V, 0-10 V, 0-20 mA, 4-20 mA, 0-1000 Ohm, PT100, PT1000 and floating contacts. Integrated power supply to generate the 24 V DC voltage for external sensors. The device can be operated with a suppy voltage of 115 to 230 V, 50/60 Hz. Maximum 300 mA supplied on the complete voltage range. Application software adjusted for detection and processing of analogue variables.
