D9412G/D7412G
Off-board Relays
The number of D8129 OctoRelays that can be connected to each Zonex terminal on the D9412G panels is limited
by the number of D8128D OctoPOPITs connected.
Using D8129 OctoRelays and D8128D OctoPOPITs together on the same Zonex Terminals is limited and
depends on the number of D8128D OctoPOPITs and D8129 OctoRelays connected to a single Zonex Bus.
Refer to Table 11 for information on the maximum number of D8128Ds and D8129s that may be connected
to a single Zonex Bus.
