Weidmüller's process instruments from the AR, UPI, R and DPA series are part of a wide-ranging line of innovative products designed for analogue signal processing. These instruments are specifically designed for the complex and demanding requirements of modern process automation applications.
The product series, ranging from simple dedicated units to complex microprocessor-controlled devices, can be used with almost all signal types and measurement sensors.
The products also offer a variety of integrated functions, such as timing delays, adjustable threshold values, high-/low-trip switching behaviour and scalable displays.
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.
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.
