4.5 Digital input cable
4.5.1 Introduction
The digital input interface on the Gazelle S1512i-PWR uses 4 pins of the 5-pin Phoenix
connector (with spaces of 5.08 mm) to input external alarms from an external device.
The digital input interface supports 2 ways of DI. Each way supports two statuses:
Status 1: the input voltage is 13–30 V.
Status 2: the input voltage is -30 to 1 V.
The condition for triggering alarms can be configured as required. By default, it is status 1.
If status 1 is configured as the alarm status, status 2 is the normal status.
