Process monitoring with relay output and display – Overview
Process monitoring
The R-SERIES – process monitoring with relay output and
display
F
The threshold monitoring modules from the R-SERIES feature
two relay contacts on the output side for the alarm function.
Each product version is designed for a defined type of signal
and sensor. These types include analogue signals such as current,
voltage, temperature (thermocouple and PT100 sensors),
frequency and conductivity.
Monitoring components with temperature measurement inputs
are equipped with wire break detection mechanisms. They
come standard with programmable functions for setpoint,
deadband, high/low-trip switching behaviour, coil energizing
and a variable timer delay on each channel.
The XFAR (U/I input) features extra extensions to the standard
functions. This includes an optional alarm function which can
be configured in connection with various input parameters,
such as a change in the signal frequency, a signal loss or for
individual signal formats. The XFAR is equipped with two alarm
outputs for more complex applications. Each can be secured
individually. The four-character LED display can be set universally.
The corresponding scaling for the input parameters is
then carried out automatically.
The user-friendly menus are easy and navigate and make it
easy to configure the operating parameters. Specific parameters
can be selected and changed using the keyboard and display.
Monitoring modules from the R-SERIES feature complete
2-kV electrical isolation. Wires are connected on the front side
with a pluggable screw mechanism. The modules can be
directly mounted on TS35/TS32 DIN rails.
