CONTROL PORT
CONTROL can be used to signal internal operating status and transmit control signals to the
amplifier. The CONTROL PORT on the DPA output stage contains three control inputs/outputs
and reference connections for VCC (15 V) and ground. The scope of delivery for the device
includes a 8-pin connector. Conductor cross-sections of 0.14 mm² (AWG26) to 1.5 mm²
(AWG16) can be used. Recommended connecting cable: flexible CU strand, LiY, 0.25 mm². The
CONTROL PORT can be configured using IRIS-Net.
Notice!
In conjunction with a DPM 8016, the inputs and outputs on the CONTROL PORT can be
incorporated into the task engine of the DPM 8016.
Use as a control input
Connections 1, 2, and 3 have an internal “pullup resistor”. For activation purposes, therefore,
the control inputs must be closed to ground via external switches, buttons, or relays. Input
voltages below 5 V are considered as ON/active, and input voltages above 10 V are considered
as OFF/inactive.
