AX Pin Assignment
the control software with an analog- or an ASCII-command. The
PWM resolution is 12-bit.
If inductive loads (relays, solenoids, etc.) are connected, it
is essential to ensure that a free-wheeling diode is mounted
parallel to the load in the reverse direction (see diagram).
Otherwise the output drivers are destroyed. The common
cathode of the internal free-wheeling diodes is brought out on
pin 9 of the upper plug DIGITAL IN. Thus, if the internal free-
wheeling diodes are to be used, this must be connected to the
positive terminal of the external power supply.
ATTENTION!
The maximum current per output must not exceed
500mA. Do not use inbound power supplies of
higher than 24VDC.
LINE OUT
An external audio amplifier can be connected to the line-out
outputs of the ProCommander
®
AX. A parallel operation with
the internal amplifier is possible under certain conditions, and
depends on the connected external amplifier. If necessary, the
function must be independently tested and verified.
LS-OUT
The ProCommander
®
AX has a built in 2x20W Class D
amplifier . At the two outputs LS-L (left channel) and LS-R (right
channel), either 4-ohm or 8-ohm speakers may be connected.
