Construction of the IP 265 Module
1.1.2 Digital 24 V Inputs/Digital 24 V Outputs
Two 9-pin sub D interfaces are located on the frontplate of the IP 265
Connect the signal lines of the sensors to the 9-pin sub D connector marked "INPUT". You can
connect up to 8 24 V digital inputs. The frequency of the input signals may be up to 10 kHz.
Connect the signal lines of the actuators to the 9-pin sub D socket marked "OUTPUT". The
response time of the 24 V digital outputs depends on the resistive load of the output circuit and the
type of output level changes (LOW -> HIGH or HIGH -> LOW; see also the Technical
Specifications). A typical response time with maximum resistive load is 70 s.
See the following diagram for the pin assignments of both interfaces.
