ST0 Series SMU [String Monitoring Unit]
PLC to control and supervise photovoltaic plants
The "ST" series of SMU [String Monitoring Unit] are PLC to manage and supervise photovoltaic plants. These devices permit the monitoring of the current and the voltage generate to the photovoltaic panels to guarantee an immediate control on all the plantsand intervene quickly in case of not correct plant working. All the "ST" serie models permit to supervise the string box temperature and have n°1 0/20 mA current analogic inputs for solarimeter inputs, n°2 PNP inputs to supervise switch disconnector and docker, n° 1 PT100 inputs, RS 485/RS 487 serial port with Modbus protocol, RS 485/RS 487 serial port with Kernel/Modbus protocol.
