- Current-relays STW 200 monitor AC-currents for falling below an adjusted limit. The ranges 12 ... 120 mA and 0.1 ... 1 A allow the monitoring of LED-Lamps as well as incandescent lamps in obstruction lights. In case of main lamp failure a relay switches on the reserve lamp. An alarm contact is available for signalling a lamp failure.
+ Measuring input 12…120 mA for LED-lamps
+ Measuring input 0,1…1 A for incandescent lamps (bulbs)
+ Adjustment range 10…100%
+ Relay for switching on reserve lamp in operating current mode
+ Relay for Alarm in closed current mode
+ Cable-length from relay to lamp up to 500 m
+ Display green = o.k., red = low current alarm
+ Housing 70 mm wide, mounting height 55 mm
