The limit-value 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 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 energising 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 attached 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 to navigate and make it easy to configure the operating parameters. Specific parameters can be selected and changed using the keyboard and display.
The monitoring components are enclosed in a rugged, rail-mountable, metal housing and feature complete isolation at 2 kV.
