Planet ISW-621 [18/28] Wiring the fault alarm contact

2.1.5 Wiring the Fault Alarm Contact

The fault alarm contacts are in the middle of the terminal block

connector as the picture shows below. Inserting the wires, the Industrial

Fast Ethernet Switch will detect the fault status of the power failure,

or port link failure (available for managed model) and then forms an

open circuit. The following illustration shows an application example for

wiring the fault alarm contacts.

the range between 12 ~ 24 AWG.

2. Alarm relay circuit accepts up to 30V, max. 3A

currents.
