Application Examples

7.1

Submersible pump

The module can be connected to high and low pressure switches, a PT100 to monitor pump temperature, and a level relay to protect
against low water. This provides a simple, integrated pump monitoring system without any extra components such as timers, relays and
temperature monitoring devices.

7.2

Compressor oil pump

The module can be used on a compressor oil pump system, to monitor conditions such as oil line pressure and oil temperature.
Interlocking the trip output with the compressor motor means that the compressor is safely shut down when a fault occurs, preventing
damage to the system.
