144 €
Loop-powered contactor for monitoring current or voltage signals The RTA421 contactor monitors industrial processes for safe operation. The unit analyzes current (0/4...20 mA) and voltage (0/2...10 V) signals and switches two independent output relays if the values exceed or fall below the preset alarm thresholds. Both thresholds are displayed in parallel on the screen. The % bar graph provides real-time information about the connected signal. It is used for pump control in the wastewater industry and for economical level measurement in silos. Input: 1 x analog (U, I) Output: 1 x transmitter power supply Power supply: Not defined
