A maximum of 32 relays can be daisy-chained together on a communication channel without exceeding the driver capabil-
ity. For larger systems, additional serial channels must be added. It is also possible to use commercially available repeaters
to increase the number of relays on a single channel to more than 32. Different GE Power Management relays may be con-
nected to the same twisted pair link providing they are all programmed with a unique address and the same baud rate.

Due to address limitations, only 31 735/737s can be put on a single channel. However a different model
of GE Power Management relay could be added to the channel increasing the number of relays to 32.
