• UL recognised components for Canada ; US; LROS. 16A Step Relays - 20 Series. The 20 Series are available as DPST-NO or SPST-NO + SPST-NC step relays. On, each successive energisation of the relay coil the contacts change state thus providing a step or "flip flop" sequence of operation. With the advantage of an override test button, it allows manual advancement of the step sequence and individual mechanical flags provides visual indication of contact status. Typical applications include the control of lighting where push on push off or sequential operation is required, automatic opening/closing of doors, gates, and so on. Use in portable or battery powered equipment requiring contact status to be maintained without continuous supply to the coil and functions where manual override operation is desired. 17.5 mm wide (EN 50022) 35mm DIN Rail mount housing Manual test button and mechanical indicators Minimum impulse duration: 0.1 Sec Maximum impulse duration: 1 hour Insulation between coil and contacts (1.2/50μ); 4 kV Nominal lamp rating: incandescent (230 V ac); 2000 W Compensated fluorescent (230 V ac); 750 W Temperature range: -40 to +40°C Protection category: IP20
