2.3.5 DI interface
The Gazelle S1020i-GL DI interface adopts the 5-pin Phoenix connector (with spaces of 5.08
mm) or the 3-pin Phoenix connector (supported by the GazelleS1020i-4GF-8GE-GL only),
which is connected with a related device for inputting external digital signals, thus monitoring
external environment alarms.
Figure 2-15 shows the DI interface on the Gazelle S1020i-4GF-16GE-GS and Gazelle
S1020i-4GF-8GE-GS.
Figure 2-16 shows the DI interface on the Gazelle S1020i-12GF-16GE-GS.

The digital input interface supports current up to 8 mA. Each channel of digital signal input
supports the following statuses:

High level: the input voltage is 13–30 V.

Low level: the input voltage is -30 to +1 V.
After login, you can configure the triggering condition of an external alarm to high level or
low level in global configuration mode, as described in Table 2-15.
