Relay Common Input
The relay common input (4TB-2) is a shared
connection between the Fault and HV on relay
outputs. This is the source of their output
voltage. It can be wired to either an AC or DC
signal. It is most commonly connected to the
24 VDC power provided at (4TB-4). This
allows the relays to output 24 VDC signals
without the use of any outside power sources.
