Chapter 2 System Components Warning: The HAWK MV-4000 output signals are compatible with voltages up to 24V. However, by default, the output signals offer low resistance. When they are on (their circuit is closed), current flows directly through them. Ensure that the circuit created between the power source, the output signal, the connected device, and return path does not cause more than 50 mA to flow through the signal. As a precaution, the output signals are individually fuse-protected up to 50 mA. HAWK MV-4000 uses resettable fuses.
The fuses protect HAWK MV-4000 if you accidentally connect their corresponding output signal to a device that sources/sinks more current than HAWK MV-4000 can safely transmit. If more than 50 mA of current goes through your HAWK MV-4000, the fuse will eventually trip. After disconnecting your HAWK MV-4000, the fuse will reset only after it has cooled sufficiently.
