Monitoring relays

CU-U900-I relay - Current monitoring

Summary

Description

Miniature current monitoring railway relay with one change-over contact. Suitable for AC or DC currents. Very sensitive and high insulation between coil and contact. Relay for plug-in mounting (CU version) or for PCB mounting (CP version).
 
The construction of the relay and choice of materials makes the CU/CP-U900-I relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to very humid environments.
 
With a very compact design and a wide range of sockets, the CU/CP-U900-I relay is an easy and flexible solution to use.
 

Application

These relay series are designed for rolling stock applications where available space is limited. The CU/CP-U900-I is used in applications for current monitoring or where switching is activated by a fixed current level.
