1.1 Power module PM-E DC24V (6ES7138-4CA01-0AA0)
Properties
● The PM-E DC24V power module monitors the supply voltage for all the electronic
modules in the voltage 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 AC120V ST, 2DI AC230V ST, and
2DO AC24..230V/1A in the voltage group of the PM-E DC24V power module.
● 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.
● The PM-E DC24V power module is suitable for fail-safe modules.
● Extended temperature range from 0 to 55°C with vertical installation.
CAUTION
Only connect the specified rated load voltage of 24 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 voltage group.
Maximum configuration per voltage group
The number of modules that can be connected depends on the total current of all modules in
a voltage group. This total must not exceed the maximum current carrying capacity.
Address space of inputs/outputs
Address space of inputs/outputs by selecting the following as an option:
Options Address space of the inputs Address space of the outputs
Status byte (S) 1 byte --
Option handling (O) 8 bytes 8 bytes
Status byte and option handling
(SO)
9-byte inputs 9 bytes (9th byte not relevant)
