DOLD measuring relays

DOLD measuring devices reliably monitor electrical quantities such as current, voltage, power, resistance etc. and signal fault conditions and disturbances. Thus, these products also protect complex systems and ensure an optimal production sequence. LEDs on the front provide visual status indications. Output contacts or interfaces to bus systems allow information transmission.
