With the rotation relay DRR10 there is always correct the phase sequence, ie the motors always run in the correct direction, even if the network or connection errors are connected. Use primarily in mobile equipment (pumps, mixers, compressors) that are...
Used either for frequency relay for monitoring the frequency in power networks, or as a speed relay for monitoring of rotating parts in machinery and plants Adjustable start-up delay, response delay and hysteresis allow optimum adaptation to the monitoring...
Digital measuring instrument for measuring installation of direct currents and voltages.
Digital measuring and switching device for measuring temperatures, DC currents and voltages.
Motor protection device to protect electrical equipment incorporating PTC thermistor sensors (PTC thermistors) from high temperatures. Even for direct monitoring of explosion-proof motors in protection type Ex e and Ex d in hazardous areas (zones 1 and...
Motor protection device to protect electrical equipment incorporating PTC thermistor sensors (PTC thermistors) from high temperatures. Even for direct monitoring of explosion-proof motors in protection type Ex e and Ex d in hazardous areas (zones 1 and...
Measuring transducer MU 2000 K can be used as input signals ac and dc voltages up to 600 V, as well as direct and alternating currents of 0 … 1/5 A measure. There are pre-programd measurement ranges are available. Further measuring range can easily...
Level relay NS 20 for level monitoring of conductive liquids. Use with three electrodes as MIN / MAX control for filling or emptying a container, with two electrodes as overfill or dry run protection The AC path is completely DC free. This is no electrolytic...
Space-saving converter for AC currents. Conversion of AC 0 - 15 A at DC 0 - 20 mA (STWA 1 AH) or AC 0 - 20/100 A of DC 4 to 20 mA (STWA 2 AH), with electrical isolation. Multiple looping of the conductor reduces the measuring range. For larger currents,...
A built-in LED displays that a current of about 2 A / AC flows through the converter. In addition, an external LED can be connected. With the STWA 1 H one can easily connect a remote consumer to a supply line, and indicate whether this is on, and receives...
