Introduction
::
Pantech's
Multiple Input Signal Isolator, model
831 is an ideal instrument for accepting various
types of inputs from field and feed the converted signals to a control
room instruments accepting upto three standard inputs. Input to
the Isolator can be from thermocouple, RTD, two-wire transmitter,
non two-wire transmitter, mV or a voltage source.
The
instrument accepts upto three inputs in any combination and range,
and provides corresponding isolated outputs of 4 – 20 mA DC/
1 – 5 V DC. All the three inputs are isolated with each other
and outputs. This enables the use of grounded thermocouples, guards
against leakage resistance and simplifies selection of safety barriers.
All outputs have common zero, which further simplifies use of any
receiver instrument without much of a problem.
The
instrument is powered from 24V DC, 110V AC or 230V AC power source.
Low
drift precession components are used for long term accuracy of the
instruments. All instruments undergo a burn-in for better reliability.
The
instrument can be mounted on a wall or back of panel, its terminations
are provided in front.
