2.3 Interface to the Process I/O
2.3.1 24 V Digital Inputs
Connect the signal lines of the plant sensors to the 9-pin sub D connector labelled "INPUT". You
can connect up to 8 sensors with 24 V signals. The frequency of the input signals may be at the
most 10 kHz. For connecting sensors with chattering contacts, you can configure an input delay in
the range of 1 to 2 ms for every input.
For the pin assignment of the 9-pin sub D connector refer to the following diagram.

2.3.2 24 V Digital Outputs
You connect the signal cables of the actuators in the plant to the 9-pin sub D socket labelled
"OUTPUT". You can connect up to 8 actuators with 24 V signals. The response time of the 24 V
outputs is dependent on the resistive load of the output circuit. It is typically 70 µs for a maximum
resistive load.
You see the pin assignments of the 9-pin sub D socket in the following diagram.
