Application

Rugged plug-in relay for extreme reliable safety critical, 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 make the D-U200 relay an easy and flexible solution to use.

Description

The relay series are designed for demanding train borne applications such as doorcontrol and standard equipped with weld-no-transfer contacts. The construction of the relay and choice of materials make the D-U200 relay suitable to withstand corrosive atmospheres, low and high temperatures, shock and vibration 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.
