D-U200 instantaneous relay with 4 contacts



Rugged plug-in relays for extreme reliable, long endurance applications in harsh environment. Proven reliable operation in switching high DC voltage / inductive loads and low currents. Compact design, choice of many options and a wide range of sockets makes the D-U200 relay an easy and flexible solution to use.


The relays series are designed for demanding train borne applications such as doorcontrol. The construction of the relay and choice of materials makes the D-U200 relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to very humid environments. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions.
All relays are standard equipped with a magnetic arc blow-out for high breaking capacity and long contact life and a back EMF suppression diode.
