The measuring and switching device for DIN rail mounting measures and regulates, depending on the configuration, the pH value or the redox voltage in aqueous solutions. The transmitter has two analog inputs. The first analog input (main input for pH value or redox voltage) is intended for the connection of combination electrodes or electrodes with a separate reference electrode. The device is also prepared for the connection of antimony electrodes. A Pt100 or Pt1000 resistance thermometer can be connected to the second analog input. There are two analog outputs and a relay changeover contact available. The relay contact can be assigned either the main value (pH value or redox voltage) or the temperature. The devices are operated and configured using buttons and the integrated LC display. Alternatively, this can also be done very conveniently via the setup connection (notebook / PC) with the included setup program. The configuration program can also be used to print out the configuration data. This simplifies the system documentation. The devices are delivered with a calibration certificate, in which the device and calibration data are documented. Power is supplied via a DC 20..30 V power pack.
