UNICONT PMM-500 universal controllersThe newest member of the successfulUNICONT controller familyNIVELCO has produced a wide range of indicating andcontrolling instruments for temperature sensors. Thenewest members of the UNICONT universal controllerfamily are the PMM-500, featuring easy programmingas well as ease of use. Since June 2011, new anddifferent versions of PMM-500 have been available,replacing most members of the PMM-300 family ina 1/16 DIN (48x48 mm) size - such as our PMG-400,also offered at a better price.The greatest improvement with the UNICONT PMM-500controllers is the wider variation of the outputs comparedto the former series. The controllers are expandable withup to 4 output modules providing a wide variation ofoutputs thanks to the modular structure of the device.An excellent quality, 2-line, 7-segment, 4-digit LEDdisplay indicates the measured and process values, programmingsteps or other settings. Flashing status LEDsindicate the modes of operation and alarms.Among the output modules there are a maximum of threerelays, 24V DC power supply for transmitters, SSR drivers,an analogue output, plus RS485 (Modbus) communication.The RS485 Modbus RTU serial line provides digitalcommunication with a PC as well as remote programming.The four-key front panel provides easy programming.EEPROM memory ensures data and program protectionagainst power-cuts.The universal input accepts a wide range of temperaturesensors (Pt-100 RTDs and most types of thermocouple),standard analogue current or voltage signals (mA, mV, V).Using the Auto-Tune mode, the instrument provides optimalsettings of control parameters without entering anyPID parameters.17
