Din rail mounted or 8 & 11 pin plug in SPCO and DPCO “mains restoration auto restart relays”. The voltage and supply sensing built into these units are designed to sense voltage dips and momentary loss of supply referred to as “Brown Outs”. This phenomena is a particular threat in the water industry and regularly occurs at remote pumping locations, especially during electrical storms. Left unchecked, a supply dip can “lock out” all or part of a control system, causing system malfunctions over a wide area necessitating engineers’ site visits, just to reset and restart a control system. By monitoring the supply these tried and proven Foxtam units will provide the “auto restart” signal to reset and restart the control system without the need for a site visit. For added convenience DPCO units are also available with the extra contact used as say a telemetry output to notify an operations centre that an incident has occurred.
These relays are designed to operate in such a way that they reset as quick, if not quicker, than standard contactor and relay coils.
On the application of the supply voltage the relay will energise after a fixed delay of 100mSec. Should the supply then be lost for 1 cycle (20mSec)* and/or dip below 80% of the nominal supply voltage, the relay will de-energise and will energise again after 100mSec when the supply voltage is restored.
*1mSec version also available on request.
