The AR SERIES of signal isolating converters, with alarm
function for process automation, provide a flexible
interface between the sensor and the control system.
The output side features analogue standard signals and
two relay outputs for limit monitoring. On the input side,
parameters can be processed depending on the module.
This includes signal isolating converters for processing
analogue signals such as current, voltage, temperature
(PT100 and thermocouple sensors), frequency,
conductivity, curve linearisation/characterisation, and
additional math functions.
The process monitoring components from the AR SERIES
come with a four-character, scalable LED display.
The scaling of the input parameters is done automatically.
External passive sensors can be supplied directly via the
input circuit of the signal isolating converter.
The user-friendly menus are easy and navigate and make
it easy to configure the operating parameters.
The monitoring components are enclosed in a rugged rail-
mountable
metal housing and feature complete isolation at 2 kV.
