4.13.1 Digital Inputs
Figure 30: Location of digital inputs.
The GTIB-30 has up to three dedicated digital inputs in the upper left of the
enclosure if the optional GTIB-30 Client I/O device is installed.
Of the three standard inputs on the GTIB-30 Client I/O device, three can be used as
feedback signals for the digital outputs of the GTIB-30. If feedback signals for the
outputs are not required, these can be used as additional independent digital inputs.
The digital inputs work on 24V logic and are optically isolated from the rest of the
system. A 24V power supply is available on the GTIB-30 Client I/O device should it
be required (available on J12 connector of GTIB-30 Client I/O device).
