RS PRO Plug In Timer Relay, 24V ac, 0.1 s → 30min, 1-Function, DPDT

An 11 pin plug in DPCO true delay off timer. The units are supply voltage selectable via the connection to different pins. Two selector switches are provided to select four different time ranges from 0.1 sec to 30 mins, fine time selection on a selected range is then achieved via a percentage potentiometer. Two green supply on LED’s are featured to indicate supply healthy. On removal of the supply voltage and therefore the commencing of timing the LED’s on this timer will extinguish. All pin details and the function information is clearly marked on the sides of the housing. The relay energises immediately the supply voltage is applied to the supply pins 10 to 2, 5 or 6 depending on the required supply voltage. When the supply voltage is removed the relay is held energised by a charged capacitor, the removal of the 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 500mSec to facilitate the full charging of the capacitor.
