Monitoring of direct or alternating voltages in live systems. If the set values are exceeded or not reached, this is indicated and a switching process is triggered. The integrated 7-segment display provides information about the causes of the error. The type of voltage to be measured (AC or DC), two measuring ranges, an upper and a lower threshold value, the response delay and the error memory (on or off) can be set using a manual input on the device. Errors can be acknowledged directly on the device or via an external contact. Operating voltage 230 V AC, 50 Hz Current consumption max. 15 mA Voltage measuring input B1 - B3 10 V to 300 V Voltage measuring input B2 - B3 1 V to 100 V Response delay 0.1 s to 9.9 s, adjustable Output / contact 2 changeover contacts (DPDT) Output / switching voltage max. 250 V AC/DC Output / continuous current max. 8 A Mechanical life 3 x 107 switching cycles Electrical life 1 x 105 switching cycles Display / error 2x 7-segment display Display LED green, red Dimensions W x H x D 50 x 69.3 x 60 mm Weight 200 g Operating temperature range -5 °C to +55 °C Storage temperature range -20 °C to +70 °C Protection class housing / terminals IP40 / IP20
