2.3.3
Digital inputs (DI)
The PP15 is equipped with 16 software-configurable digital inputs to
allow different functions to be triggered within the PP15.
The current drawn at 24 VDC is approx. 4.2 mA for each input.
Inputs DI 1-DI 10 can be used as push buttons in parallel to the keys
0-9 on the front panel. This allows the presets to be remote controlled.
Alternatively, inputs DI 1-DI 12 can be designed as switches (zone call
function). In this configuration, the assigned preset is active as long as
the switch is closed. After that, the last preset selected using the keys on
the front panel is recalled.
Input DI 15 (Poll on/off) can be used to disable continuous monitoring of
the connected amplifiers. This may be necessary if the amplifiers are
temporarily disconnected from the network (CAN-Bus) or the mains.
Input DI 16 (alarm contact) is the input (Preset) with the highest priority.
Note:
If no external wiring is required, configure the “Alarm
contact” digital input as high-active N/O contact (normally
open contact).
