Characteristics of the Controller Power Distribution Module
The Controller Power Distribution Module (CPDM) has three 24 Vdc power connections:
oMain power (Ctrl)
oExpert I/O power (Exp.)
o24 Vdc I/O Power Segment power (I/O)
The state of these three power connections is indicated by a set of LEDs on the CPDM:
The following table describes the CPDM LED display:
|

Description |
|---|---|---|---|
|
Exp (Expert I/O power) |

|
I/O (24 Vdc I/O Power Segment power) |

The Main power serves the TM5 power bus, the Serial Line port, the USB port, any PCI modules that may be installed, and power for the controller electronics.
The Expert I/O power serves the Expert I/O module inputs and outputs, the power for the embedded Encoder port, and power for the Expert I/O module electronics.
The 24 Vdc I/O power segment power serves the Regular I/O modules inputs and outputs, as well as providing power to the first segment of the 24 Vdc I/O Power segment for any optional I/O slices of the local configuration.
