Circuit
Operation
The AL4006 provides sixteen outputs (SW1-SW16) for driving
relays or other binary devices. The relay outputs are controlled by
the levels of sixteen consecutive DMX512 channels, starting at the
base address.
The SW0 output will switch low when the base address channel
exceeds
50%.
(The AL4009 will switch high when the base address channel exceeds
50%. )
The maximum sink current of the relay outputs is 35mA. For most
relays
an external darlington driver package will be required (See
Application
drawing). An output level of 0V represents relay on. (The AL4009 has
reversed polarity relay outputs, so an output level of 5V represents
relay on).
The AL4006 provides two analogue outputs which represent the
DMX512 levels of two consecutive DMX512 channels, starting at the
base address.
The outputs are TTL Pulse width modulated at a frequency of
15.625khz. These outputs can be used directly for motor speed
control, or integrated and amplified for an analogue 0-10V output.
The maximum sink current of the analogue outputs is 35mA.
