Electrical Connection¶
The CS31-HA Bus module CI590-CS31-HA is plugged on CS31 Terminal Unit TU551-CS31 or TU552-CS31. Hereby, it clicks in with two mechanical locks. The Terminal Unit is mounted on a DIN rail or with two screws plus the additional accessory for wall mounting (TA526).
Note
Mounting, disassembling and electrical connection for the Terminal Units and the I/O modules are described in detail in the S500 system data chapters.
The electrical connection is carried out by using the 40 terminals of the Terminal Unit TU551-CS31/TU552-CS31. It is possible to replace the CI590-CS31-HA without loosening the wiring.

Caution
:strong:Risk of damaging the PLC modules!
The PLC modules must not be removed if the plant is powered on. Make sure that all voltage sources (supply and process voltage) are switched off before removing or replacing a module.
Caution
:strong:Risk of damaging the PLC modules!
The PLC modules can be damaged by overvoltages and short circuits. Make sure that all voltage sources (supply and process voltage) are switched off before starting system operation.
The module provides several diagnostic functions (see chapter Diagnostics).
The following figure demonstrates electrical connection of the configurable digital inputs/outputs. The digital input/output C0 is connected as an output and the digital input/output C1 is connected as an input. Connect the digital inputs/outputs C2 … C15 in the same way.
CI590-02
Caution
:strong:Risk of influences to the connected sensors!
Some sensors may be influenced by the deactivated module outputs of CI590-CS31-HA. Connect a 470 Ω / 1 W resistor in series configurable inputs/outputs C8/C9 if using them as Fast Counter inputs to safely avoid any influences.
The meaning of the LEDs is described in the chapter Displays.
