Hi,

I need to power 5V DC the TTL converter,

сan I take this voltage from the module 6ES7138-4DE02-0AB0?

In Operating Instructions, 06/2010, A5E00124867-07 is shown that the module 6ES7138-4DE02-0AB0 has a power terminal #2 but this 24V DC,

I need an extra power source?

Сan i use some other count module?

I need to read the count pulses (TTL 5V) from linear scale HEIDENHAIN LS403,

This liner scale has an analog output 11uApp sine wave output 20um signal period,

We have a special converter for linear scale HEIDENHAIN EXE102  (Interpolation and

Digitizing Electronics), this converter has an output TTL (5V), but it also requires power supply 5V DC, where can i get it?

usually such converters are connected to Sinumerik counting input, but we have a system based on ET200S.

Hello _oleksandr_,

you need a extra supply with 5 V DC for your linear scale encoder.

The module can only supply encoder with 24 V DC.
Only the input can read signals with TTL.

Please tell us the data of your encoder, then we can make a specific suggest.

For instance have Phoenix Contact DC/DC converter.
The part DC/DC converters - MINI-PS- 12- 24DC/ 5-15DC/2 - 2320018 could be helpful to solve your problem.
