PLA33RX E DL is an universal measuring instrument with high accuracy class, great sampling rate 25.6 kHz (50 Hz), various input / output combinations and other features. Instrument is designed for measuring of electrical parameters in low voltage and high voltage grids for 2, 3, 4 line and TN, TT grids. PLA33RX E DL can be as optionally equipped by 1GB Flash on-board memory to behave as a measured data logger with possibility of logged data download via RS485 interface. Communication interface use Modbus RTU protocol and as an optional variant it is possible to have PLA33RX E DL with Profibus communication interface.

Flash memory

Variant M of an instrument has 1 GB ob board flash memory for recording measured parameters that can be processed by software PMS or any other SW or SCADA SW. Data stored in on board flash memory can be read by standard Modbus functions for easy implementation.

Inputs / Outputs

Instrument can be, according to the variant, equipped by 4 x digital fully programmable inputs / outputs, 3 x relay outputs 3A/250VAC. PLA33RX E DL can also have analogue output 4 – 20 mA.

Power Grid Monitor App

Power Grid Monitor is a mobile application available for Android and iOS operating systems that allows access to online grid analyzer data anywhere in the world. This application communicates with the company server, which only serves as an intermediary between the network analyzer and the application itself. All data is stored in the network analyzer. To access online data from a personal computer or device with a different operating system, you can use the web interface of the Power Grid Monitor application, which is available through any web browser at www.pgm.bmr.cz.
