Time setting on relative scale: 1 to 10 with respect to the damaging the device(See wiring diagram). pins Y1 and A2 driven by the trigger contact without It's possible to wire an additional load(i.e. a relay) between again. time period begins as soon as the trigger contact is opened before the end of the delay time the relay keeps ON,a new when the trigger contact is closed again. If it is closed the power supply is disconnected. The relay operates again The relay releases at the end of the set delay time or when The time period begins when the trigger contact is opened. The relay operates as soon as the trigger contact is closed. 2 Operating Diagram DBA52 Additional Load Yellow LED working mode Timing: Slow blinking General Specifications Time Setting Mode of Operation Power ON delay ≤ 100 ms Indication for Power supply ON LED, green Output relays ON LED, yellow (flashing when timing) Environment (EN 60529) Degree of protection IP 20 Pollution degree 2 (IEC 60664) Operating temperature -20° to +60°C, R.H. < 95% Storage temperature -30° to +80°C, R.H. < 95% Housing Dimensions 17.5 x 81 x 67.2 mm Material PA66 Weight Approx. 75 g Screw terminals Tightening torque Max. 0.5 Nm according to IEC EN 60947 Approvals UL, CSA CE Marking Yes EMC Electromagnetic Compatibility Immunity According to EN 61000-6-2 Emission According to EN 61000-6-3 Timer Specifications According to EN 61812-1 Function Dr - Delay on release Power supply Relay ON Trigger input T LED L(+) N(-) � A1 15 16 18 A2 S Y1 Wiring Diagram Lower knob: Setting of time range.
