Installation Guidelines S5-90U/S5-95U
3.3.5 Connecting the Onboard I/Os of the S5-95U
Use the following parts to connect the onboard I/Os of the S5-95U.
• 40-pin front connector for digital inputs and outputs
• 15-pin sub D connector for analog inputs and outputs
• 9-pin sub D connector for interrupt and counter inputs
Connecting Digital Inputs and Outputs
The signal cables to the digital I/Os must be connected to a 40-pin front connector.
Two types of front connectors are available:
•
Front connectors with standard screw-type terminals (see Section 3.3.1)
• Front connectors with crimp-snap-in terminals (see Section 3.3.1)
Every input and output (channel) has a terminal assigned to it on the front connector. The 16 inputs
(IN) and the 16 outputs (OUT) are numbered from 32.0 to 33.7. Use a 24 V DC power supply for all
digital inputs and digital outputs.
Example: A field device is connected to input I 32.4. A lamp is connected to output Q 33.3.

* For the power supply of outputs
32.0 to 32.7, L+ must be connected
at least to terminal 1 and M to terminal 10;
outputs 33.0 to 33.7 are to be supplied
by connecting L+ at least to terminal 11
and M to terminal 20.
