Timers Delay on Operate Types AAM, BAM • 6 selectable time ranges: 0.1 s to 10 h • Knob-adjustable time setting • Switch selection of time range • 8- or 11-pin circular plug • Output: 8 A SPDT • LED-indications for relay and power supply ON • 48 x 48 mm housing Product Description Ordering Key Mono-function, plug-in, delay on operate time relay. Adjustable time range from 0.1 s to 10 h divided into 6 individual ranges. Easy frontpanel mounting if necessary. Often used to prevent overloading the power distribution system, when e.g. pumps or motors should not be switched on at the same time.

At the end of the timing period, the relay operates and the red LED is ON - the load is activated. Time Setting To reset the output relay the power supply must be interrupted for at least 100 ms (du- ring timing) or 50 ms when the timing period has elapsed.
