| MODEL 838-EXPRESSION COMPUTATION MODULE
|
| |
| Introduction
|
| |
|
Pantech's Computation Module, model 838 is designed to accept upto three inputs and provide a computed output of 4 – 20 mA DC capable of driving a load of upto 800 as per the equation
OUTPUT – (A + BX) * (C + DY) / (E + FZ) where A, B, C, D, E & F are constants and X, Y & Z are three inputs. The module accepts 4 – 20 mA DC signal from two wire and not two wire transmitters. The transmitter power supply to feed upto three two wire transmitters is available as option. The module also accepts 1 – 5 V DC signals.
The module is available in a wall-mounted housing. The 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. |
