Function 81 [t-head2]

Pulse generating with fixed pulse

The actuating voltage is applied to terminals A1 and A2 via an actuating contact. After the set delay time has elapsed the changeover contact of the output relay goes to position 15-18 (25-28) and returns to its original position 0.5-15 (16-25) after 26 s. This function is therefore a fleeting pulse with a time delay.
