GDIS is designed for protecting DCS ( distributed control system ) and PLD (programmable logic controller), it broadly heightens the safety of important control system through suppressing interruption derived from ground potential rising.
It is suitable for the key sensitive control equipment (such as DCS, PLC) in continuous production process, effectively preventing the high frequency interference of the ground network,suppressing the secondary equipment interference caused by ground potential counterattack, ground overvoltage, etc., reduce the risk of comprehensive automation control system, Instrument malfunction and measurement error.
Effectively isolate network interference, reduce the risk of interference with the control system, prevent unplanned stop due to a local power outage and serious catastrophes such as a fire explosion by a secondary accident.
