:: Signal Processors : Linearisation Module

> Introduction ::

Pantech's Linearisation Module, model 839 is designed to provide linear output for most of the non-linear signals. It provides an output of 4 – 20 mA DC capable of driving a load of upto 800. The module incorporates a multiplier/ divider circuit, which performs a polynomial function to linearise, the input.

The module accepts 4 – 20 mA DC signal from two wire and not two wire transmitters. The 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 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 or 24 V DC power sources. 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.
