Monitoring of direct or alternating currents 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 cause of the error. The type of current to be measured (AC or DC), an upper and lower threshold value, the response delay and the error memory (on or off) can be set using manual input on the device. The two current measuring ranges can be selected using the connection terminals. Errors can be acknowledged directly on the device or via an external contact.
