Simple din rail mounted or 8 & 11 pin plug in dedicated true delay off timers (capacitor discharge type), with dedicated coil voltage and time range. These timers are SPCO output with a DPCO option on the 8 and 11 pin plug in versions. These timers can also on request, be factory set with an exact time, thus ensuring absolutely no operator interference. The timers feature a red LED to indicate supply healthy. All terminal details along with the CE mark is clearly marked on the sides of the housing.
The relay energises immediately the supply voltage is applied, when the supply voltage is removed the relay is held energised by a charged capacitor, the removal of the power supply voltage instigates the timing period. After the timing period has elapsed the relay will de-energise. A break in the supply of less than the set time will therefore be ignored. Since the relay is held energised after the removal of the supply by a charged capacitor, it is necessary that the initial connection of the supply voltage must be at least 300mSec to facilitate the full charging of the capacitor.
By nature a true delay off timer uses different relay technology, by the means of a magnetically latching mechanism. However, if subjected to undue physical shock, for example “in transit” the contacts maybe on initial connection be in the incorrect state. If this is the case this can be easily rectified by the connection and removal of the auxiliary supply voltage. Thus allowing the contacts to time out and return to the correct state.
