Square Root Extractor Module

> Introduction ::

Pantech's Square Root Extractor Module, model 836 is designed to provide linear output for the non-linear flow signal. It provides an output of 4 – 20 mA DC capable of driving a load of upto 800. The input-output relationship can be defined as OUTPUT = SQUARE ROOT OF INPUT.

The module accepts 4 – 20 mA DC signal from two wire and non two wire transmitters. Transmitter power supply to feed a two-wire transmitter is available as option. The module also accepts 1 – 5 V DC signals.

The module is also available in Euro card format of 3U height and alternatively in a wall mounted housing. 20 Euro card modules can be housed in a 19” Euro card cage. The Euro card modules can be powered from 24V DC power supply whereas wall mounted modules can be powered from 110V AC or 230V AC too. Power supply is isolated from rest of the electronics.

The modules incorporate low drift operational amplifiers and industrial grade components. Burn in of each module ensures long trouble free operation.
