Description
Plug-in current monitoring railway relay with two change-over contacts. Suitable for AC or DC currents.
Proven reliable operation in switching high DC voltage / inductive loads and low currents. Standard equipped with magnetic arc blow-out for high breaking capacity and long contact life. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions.
The construction of the relay and choice of materials makes the DI-U900 relay suitable to withstand low and high temperatures, shock & vibrating and dry to very humid environments.
Compact design, choice of many options and a wide range of sockets makes the DI-U900 relay an easy and flexible solution to use.
Application
These relay series are designed for demanding rolling stock applications. The DI-U900 is used in applications for current monitoring or where switching is activated by a fixed current level.
