10.2 PM-E 24 VDC power module (6ES7 138-4CA00- 0AA0)
Order number
6ES7 138-4CA00-0AA0
Properties
• The PM-E 24 VDC power module monitors the supply voltage for all electronics
modules which are part of the potential group. The supply voltage is supplied
via the TM-P terminal module
• All electronic modules can be inserted in the potential group of the PM-E 24
VDC power module, except for 2DI AC120V ST, 2DI AC230V ST and
2DO 24--230 VAC/1 A.
!
Caution
Only apply the specified rated load voltage of 24 VDC to the TM-P terminal
module of the power module.
The rated load voltage applied must correspond to the power supply of the
electronic modules in the potential group.
• The current status of the power module is saved in the process image of the
inputs (PII) via the status byte. The update is independent of enabling the ”No
load voltage” diagnosis (see Appendix C).
