Weidmüller URTAR 7940010250 Process monitoring relay No. of relay outputs: 2

Process monitoring. 2-/3-wire PT100, Ni120. The signal isolating transformer with alarm function of the AR-Series offer within the process automation a flexible interface between sensor and control system. The output side are available analogue standard signals and two relay outputs for limit monitoring is available. On the input side module-specific various parameters can be processed. This includes signal isolating converter for processing of analog signals, such as current, voltage, and temperature (PT100 and thermocouple sensors), frequency, conductivity, curve linearization/characterisation and other mathematical functions. The process monitoring blocks of the AR-series are equipped with a four-digit scalable LED-display. The respective scaling of the input parameter is applied automatically. External passive sensors can be connected directly through the input circuit of the signal isolation transformer can be supplied. The configuration of the operational parameter is set by the user-friendly menu navigation is simplified. With 2 KV completely separate monitoring components are in a robust rail mountable metal housing.
