Outputs
PR 5510/09 outputs (pins 2 ... 24) use common GND as a reference potential and open collectors.
A non-activated output has high impedance, and an active output has a voltage by approximately
0.9 V higher than GND.
The load to be connected is applied between the collector [pins 2 … 24,(25*)] and Uext [PIN 1].
Input
When using as DATA_IN, the input (pin 25) can control the 23 outputs. As an output, data is
“continuous/hold/tristate“ and its signal can be configured (TTL/24V active (high/low). It is applied to
pin 25 – DATA_IN of the 26-pin connector and is effective only with DIL switch S101-1 = OFF and
S101-2 = ON.
