Electrical Connection

The Encoder & PWM Module CD522 can be connected to the following devices via the I/O-Bus connector:

  • FBP Interface Module DC505-FBP
  • CS31 Bus Module DC551-CS31
  • AC500 CPUs (PM5xx)
  • other AC500-I/O-devices.

Note

Mounting, disassembling and electrical connection for the Terminal Units and the I/O modules are described in detail in the S500 System Data System Data AC500.

The electrical connection is carried out by using the 40 terminals of the Terminal Unit TU515/TU516 I/O Terminal Units TU515 and TU516 for I/O Expansion Modules.

The internal power supply voltage for the module’s circuitry is carried out via the I/O-Bus (provided by a Bus Module or a CPU). Thus, the current consumption from 24 V DC power supply at the terminals L+/UP and M/ZP of the CPU/Bus Module increases by 2 mA per CD522.

The external power supply connection is carried out via the UP (+24 V DC) and the ZP (0 V DC) terminals.

Caution

:strong:Risk of damaging the PLC modules!

The PLC modules must not be removed when the plant is powered on.

Make sure that all voltage sources (supply and process voltage) are switched off before you are 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 you are beginning with operations at the system.

The module provides several diagnosis functions (see chapter Diagnosis Encoder & PWM Module CD522).
