Virtual Power Meter, RS232
The 845-PE-RS, virtual meter provides easy integration into automation systems (e.g. PLC) using RS-232 in their communication infrastructure. It also allows turning the customer’s PC or laptop into a full-fledged Newport laser power/energy meter.
The sensor is connected to the 845-PE-RS which sends the measurement results to the PLC or the destination computer. The 845-PE-RS has an analog output which provides an output voltage proportional to the power/energy measured.
When using the 845-PE-RS with a PC/Laptop, just install the PMManager software, plug the sensor into the 845-PE-RS module and connect the 845-PE-RS with a standard RS-232 cable to a PC serial port or USB to RS-232 adapter.
You can connect several 845-PE-RS modules to the PC at the same time.
