11.3 PM-E 24–48 VDC power module (6ES7138-4CA50-0AA0)
Order number
6ES7138-4CA50-0AA0
Features
• The PM-E 24–48 VDC power module monitors the supply voltage for all the
electronic modules in the potential group. The supply voltage is fed in by means
of the TM-P terminal module.
• You can use all the electronic modules except the 2DI 120 VAC Standard,
2DI 230 VAC Standard and 2DO 24–230 VAC/1 A in the potential group of the
PM-E 24–48 VDC power module.
• Control interface (PIQ) and feedback interface (PII) in the process image for
option handling (see Appendix C).
• The current status of the power module is stored in the status byte in the
process input image (PII). This is updated irrespective of whether the "No Load
Voltage" diagnosis has been enabled (see Appendix C).
• The PM-E 24–48 VDC power module is suitable for fail-safe modules.
Caution
!
Only connect the specified rated load voltage of 24–48 VDC to the TM-P terminal
module of the power module.
The connected rated load voltage must correspond to the supply voltage of the
electronic modules in the potential group.
