Description
Plug-in railway relay with 4 change-over contacts. Standard
equipped with a back EMF suppression diode and magnetic
arc blow-out for high breaking capacity and long contact
life. Proven reliable operation in switching high DC voltage
/ inductive loads and low currents. 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 D-U200 relay suitable to withstand corrosive
atmospheres, 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 D-U200 relay an easy and flexible
solution to use.

Remarks:
•
Umin is the must-operate voltage at which the relay has picked up in all circumstances (worst-case situation), in practice the relay picks up at a lower voltage
•
Udrop-out is the must-release voltage at which the relay has dropped-out in all circumstances (worst-case situation), in practice the relay drops out at a higher voltage
•
Always select the nominal voltage as close as possible to the actual voltage in the application
