Outputs 9-16 can be utilized additionally as
Switching to PWM
ProCommander LX, as soon as the channel is controlled by the
control software with an analogue- or an ASCII-command. The
PWM resolution is 10-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 plug. Thus, if the internal free-wheeling diodes are
to be used, this must be connected to the positive terminal of
the external power supply.
The maximum current per output must not exceed 2A.
RS232-2/ANALOG 1-4 (0-10V Output)
The serial interface RS232-2 of ProCommander LX is
assigned that a null-modem cable can be used for connection
to a computer.
Additionally four 0-10V analogue outputs with a 10-bit
resolution are available. The maximum current per output is
15mA. To achieve 10V output, the supply voltage must be
higher than 13V. With a power supply of 12V a maximum output
voltage of 9.8V will be achieved.
ProCommander LX pin assignments
output is done automatically by the
PWM outputs.
