monitoring cable infrastructures
Monitoring the cable infrastructure in direct current railways is an important function for safe operation. The self-sufficient WITT-CM and WITT-WB systems enable permanent monitoring of the power or return cables.
Threshold values are signalled via changeover contacts.
The WB devices can transfer the measurement data to third-party systems using communication protocols.

CM400 Cable Monitor
The CM 400 is a self-resetting cable monitoring device for railway applications. It detects cable faults in high-voltage direct-current systems, particularly in the overhead contact line and power supply infrastructure of electrified rail lines, thereby contributing to the operational safety and availability of the cable systems.

WITT CM 200 cable monitoring
The fully analog CM200 is used to detect changes between two potentials. A typical application is monitoring shields for insulation faults or interruptions. The operating status is indicated by LEDs or potential-free signal contacts. The CM 200 operates without auxiliary power.

WITT WB-CM 3
The WITT WB-CM3 monitors the insulation between the shield or conductor and an earthing point and signals the event via potential-free signaling contacts. Measurement data can also be transferred to third-party systems.
