Hello All

i want use Loga LOGO! 24RCE (AC/DC) module.

May i use some input ac and other dc 24? (example i1 24ac i2 24dc)

thank for help

Hello Toeternietoe,

he means a LOGO! 24V AC7/DC.

necyil,         [ LOGO! 24RCE (AC/DC) ]

I suggest strongly to read the manual (A5E33039675) for what to look out for when wiring the LOGO!. The below wiring diagram is also there.. note that mixing phases are allowed but it must be kept in groups of 4 as shown.

Mixing the DC and AC on the input side is not possible however. Pin P2 is used as reference for measuring the input .. this is either AC or DC. That means the sensor voltage must be the same as the supply voltage to the LOGO!

As the outputs are relays.. the voltage may be mixed as you want to because the relay connections are not linked internally to a common like the inputs.

Does this help you?

Dear William

many many thanks for your answere. You are right. All input must be AC24V. Not possible use mix.

..or all as 24Vdc.

It depends on the application, but personally I stay away from AC as control voltage. Plus you have some short circuit protection when using switch-mode 24Vdc power supply.. if you do not make the capacity (amps) of the PSU too big. Some PSUs even have a signal feedback.

Regardless - fuses can be your friend.
