Relay Board ( Remote ) BRD25EWRB - B
In the remote version the Comms In and Out Terminal Block TB9 is cabled to the RS 485 Comms
terminal block TB3 on the Main Card 302 – 7690 or LED Mimic and can be installed up to 1.2kms
from the FACP.
Note#1:
This version can be powered from the panel or an external 27 volt source due to the on
board switched mode supply. Quiescent Current of both boards is 16mA
Note#2:
In a system there can only be either a remote
OR
an internal board, not both.
