Measuring & Monitoring Relays

For more than 60 years, Dipl-Ing W Bender GmbH & Co KG offers measuring, monitoring and protective systems to monitor the electrical safety of machines and systems. Bender measuring and monitoring relays are capable of monitoring various parameters in main and auxiliary circuits. They serve as an essential early-warning system so that errors and faults can be detected and signalled at an early stage and so that the system can be shut down immediately in the case of critical plant statuses. Operational interruptions are reduced along with property and plant damage. As a result, costs can be cut dramatically. Monitored variables: voltage, current, frequency, phase sequence, phase failure, asymmetry, fault voltage, loop resistance, earth faults. Impressive advantages (420 series): rapid true rms measurement across a wide frequency range; large LC display for indicating measured values and for parameterisation purposes; two response values/alarm relays that can be set separately; automatic preset function of response values; measured value memory with display function for first operating value; and flexible start-up, response and release times.
