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.
