Page 3: General Description
Thank you for choosing a NIVELCO instrument. We are sure that you will be satisfied throughout its use! 1. GENERAL DESCRIPTION The UNICONT PMG-411, PMG-412 and PMG-413 universal analogue PID-controllers can be used for temperature measurement with a Pt-100 resistance thermometer or different thermocouples. The UNICONT controllers are also suitable for processing and display the signals of field transmitters with 4-20 mA and 1-5 V DC or 0-10 V DC output. -
