2 Specifications are subject to change without notice (21.07.08) 67.2 18.7 17.5 Dimensions Operating Diagram DBA52 The relay operates as soon as the trigger contact is closed. The time period begins when the trigger contact is opened. The relay releases at the end of the set delay time or when the power supply is disconnect- ed. The relay operates again when the input contact is closed again. If it is closed before the end of the delay time the relay keeps ON, a new time period begins as soon as the trigger contact is opened again. Additional Load It's possible to wire an addi- tional load (i.e. a relay) between pins Y1 and A2 driven by the trigger contact without damaging the device (see wiring diagram).
