4.13.2 Digital Outputs
The GTIB-30 has up three dedicated digital outputs if the optional GTIB-30 Client
I/O device is installed.
The three digital outputs are realized via three SPDT relays on the optional GTIB-30
Client I/O device. A functional schematic of the SPDT relay is shown in Figure 32.
The switch position is controlled by the GTIB-30 via the coil. The user has access to
the normally open (NO), normally closed (NC) and the common (Common)
connection of the relays.
These relays are associated with the IO1, IO2, and IO3 connectors described in the
previous section.

The specifications of the relay contacts are provided in Table 10. Exceeding these
specifications will permanently damage the device and its components. Should
higher current rating be required, the built in relay can be configured to switch larger
external power relays.
