Terminals are designated as Normally Open, Common, and

Normally Closed.

This relay’s factory default use is undefined at this time.

(20) Control Relay Ground Terminal

This is a ground pin for the auxiliary output voltage from the

main DC bus. This terminal can be used for the creation of a

wetting voltage for the internal relay contacts

(21) Control Relay VDC

This is actually an unregulated auxiliary output voltage from

the main DC bus. In the case of the RE24-4500, this voltage

will be 24 V

and can be used as a wetting voltage directly for

the internal relays. In the case of the RE48-4500 this voltage

will be 48 V

and can be used to wet 48V

contacts current

limited to 1 amp.
