Wiring the Power Supply

Overview

To distribute current for the 24 Vdc I/O power segment(s) and TM5 power bus according to the power distribution description, the following modules are connected to an external source:

oController Power Distribution Module (CPDM)

oInterface Power Distribution Module (IPDM)

oReceiver module (TM5SBER2)

oPower Distribution Module (PDM) TM5SPS1•

oPower Distribution Module (PDM) TM5SPS2•

Source power for these can come from one or more supplies. Your requirements are dictated by:

ovoltage and current needs

oisolation requirements

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system to meet the EMC requirements.

Wiring the Controller Power Distribution Module (CPDM)

The CPDM is the connection of the controller to the external 24 Vdc power supplies and the beginning of the power distribution for the local configuration. Power can be supplied by two or three external isolated power supplies depending on current needs and capabilities.

There are three power connections to be made to the CPDM from your source power supplies:

The following figure shows a CPDM wired with two separate external 24 Vdc power supplies:

 

(1)   External fuse, Type T slow-blow, 3 A, 250 V

(2)   External fuse, Type T slow-blow, 2 A, 250 V

(3)   External fuse, Type T slow-blow, 10 A max., 250 V

PS1/PS2   External isolated power supplies 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system. If you do not interconnect the 0 Vdc circuits of the external power supplies, the status LEDs may not function correctly. In addition, there may potentially be more significant consequences such as an explosion and/or fire hazard.

(1)   External fuse, Type T slow-blow, 3 A, 250 V

(2)   External fuse, Type T slow-blow, 2 A, 250 V

(3)   External fuse, Type T slow-blow, 10 A max., 250 V

PS0/PS1/PS2   External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system. If you do not interconnect the 0 Vdc circuits of the external power supplies, the status LEDs may not function correctly. In addition, there may potentially be more significant consequences such as an explosion and/or fire hazard.

Wiring the Interface Power Distribution Module (TM5SPS3)

The IPDM (TM5SPS3) is the first connection of the distributed configuration to the external 24 Vdc power supplies. Power is supplied by two external isolated power supplies.

There are two power connections to be made to the IPDM (IPDM TM5SPS3) from your source power supplies:

 

(2)   External fuse, Type T slow-blow, 1 A, 250 V

(3)   External fuse, Type T slow-blow, 10 A max., 250 V

PS1/PS2   External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system. If you do not interconnect the 0 Vdc circuits of the external power supplies, the status LEDs may not function correctly. In addition, there may potentially be more significant consequences such as an explosion and/or fire hazard.

Wiring the Receiver Module (TM5SBER2)

The receiver module (TM5SBER2) is the first connection of the remote configuration to the external 24 Vdc power supplies. Power is supplied by two external isolated power supplies.

There are two power connections to be made to the receiver module (TM5SBER2) from your source power supplies:

 

(2)   External fuse, Type T slow-blow, 1 A, 250 V

(3)   External fuse, Type T slow-blow, 10 A max., 250 V

PS1/PS2   External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system. If you do not interconnect the 0 Vdc circuits of the external power supplies, the status LEDs may not function correctly. In addition, there may potentially be more significant consequences such as an explosion and/or fire hazard.

Wiring the Power Distribution Module TM5SPS1•

The TM5SPS1• (PDM) divides the 24 Vdc I/O power segment into several separated 24 Vdc I/O power segments. Each separated 24 Vdc I/O power segment is supplied by one external isolated power supply depending on current needs and capabilities.

There is one power connection to be made to each TM5SPS1• (PDM) from your source power supplies:

The following figure shows the wiring to supply the 24 Vdc I/O power segments of a local configuration:

 

(1)   External fuse, Type T slow-blow, 3 A, 250 V

(2)   External fuse, Type T slow-blow, 2 A, 250 V

(3)   External fuse, Type T slow-blow, 10 A max., 250 V

(4)   Approved emergency stop device

PS1/PS2/PS3/PS4   External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system. If you do not interconnect the 0 Vdc circuits of the external power supplies, the status LEDs may not function correctly. In addition, there may potentially be more significant consequences such as an explosion and/or fire hazard.

NOTE: The requirements for the power supply are different for the input and the output slices. An emergency stop is generally used with the power supply providing power for output slices.

Wiring the Power Distribution Module TM5SPS2•

The TM5SPS2• (PDM) divides the 24 Vdc I/O power segment into several separated 24 Vdc I/O power segments and reinforces the TM5 power bus.

Selecting a 24 Vdc power supply should be based on current needs and capabilities.

Each separated 24 Vdc I/O power segment is supplied by one external isolated power supply depending on current needs and capabilities.

There are two power connections to be made to each TM5SPS2• (PDM) from your source power supplies:

In the following example, the PS1 is connected to the Main power and to the Embedded Expert I/O connections of the CPDM. In this case the 2 TM5SPS2• PDMs are connected to PS1 to supply the TM5 power bus:

 

(1)   External fuse, Type T slow-blow, 3 A, 250 V

(2)   External fuse, Type T slow-blow, 1 A, 250 V

(3)   External fuse, Type T slow-blow, 10 A max., 250 V

(4)   Approved emergency stop device

PS1/PS2/PS3/PS4   External isolated power supply 24 Vdc

NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system. If you do not interconnect the 0 Vdc circuits of the external power supplies, the status LEDs may not function correctly. In addition, there may potentially be more significant consequences such as an explosion and/or fire hazard.

NOTE: The requirements for the power supply are different for the input and the output slices. An emergency stop is generally used with the power supply providing power for output slices.
