JUMO 508663 Messumformer/ Schalter für pH-Wer

This 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 primary analog input (main input for pH- and redox voltage) is intended for the connection of combination electrodes or electrodes with separate reference electrode. The device is also prepared for the connection of antimony electrodes. The second analog input is for connection of an RTD temperature probe Pt100 or Pt1000 for temperature compensation. There are two analog outputs and a SPDT relay (changeover contact) available. Either the primary value (pHvalue or redox voltage) or the temperature can be assigned to the relay contact. The devices can be operated and configured using the front face buttons and the integrated LCD, or the configuration can also be done very conveniently via the setup port (notebook/computer) using the optional cable and setup program. It is possible to save and print the configuration data from the setup program, thus simplifying plant documentation and allowing for easy downloading of the configuration file to multiple units. The devices are supplied with a calibration certificate in which the device data and calibration data are documented. The voltage supply is provided by a power supply unit DC 20..30 V.
