APPLICATIONS
Current monitoring and alarms
for DC equipment
DC pumps and fans
Check whether current is above or below the defined operating range. Test the settings with the actual load.
DC circuits and PLCs
Use relay contacts to provide a status signal or command to external control and interlock circuits.
Operating limits to understand
50 A is the sensor rating, not the relay contact rating. The module measures current and signals an alarm. Actual load disconnection requires external equipment suited to the voltage and load.
This does not replace a DC fuse or circuit breaker and is not a high-speed short-circuit protection device. Test alarm, load disconnection, reset and supply/sensor failure behaviour before use.
