Function

PLA33RX 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. Analyser PLA33RX DL can be as optionally equipped by 1 GB 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 DL with Profibus communication interface.

Flash memory

Variant M of an instrument has 1 GB on board flash memory for recording measured parameters that can processed by software PMS or any other SW or SCADA SW. Data stored in on board flash memory can be read by standard Modbus RTU 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 can also have analogue output 4 – 20 mA.

Inputs / Outputs

Profibus

Multifunction meter PLA33RXDL can be equipped by an interface Profibus DP-V0, that allows fast regular data exchange. In order to provide fresh and actual data, analyser computes some parameters not only in 200ms interval but also in interval of 20 ms. PLA33RXDL offers data exchange up to 744 B sorted in 6 pages with max communication speed 12 Mbit.

Software

Software PMS - Power Monitor System offers possibility for full analyser configuration of PLA33RX. More over it is a tool to define recording template, alarms, and defined events and transients limits for historical data evaluation. Another part of PMS SW is used for historical data evaluation and report generation.
