Hi all.

I have question about current transformer.

We have to measure current on two motors which power is 4kW.

Idea is to put two current transformers, one transf. to one phase of first motor, and second transf.

on one phase of second motor.

I never before work with this.

Sso I need information is there current transformer which output is

4-20mA (or 0-20mA) which is suitable to connect to PLC?

Or we need some kind of transducer?

Best regards,

Miloš

Hello Milosh,

Take a look this type of transducer from Phoneix Contact:

PHOENIX CONTACT | Current transducers - MCR-SL-S-100-I-LP ...

if it can help you, there are also other types, do a search on the site of the Phoneix

Hello Milosh;

Another source would be the EAC series of current transducers from Eaton/Cutler-Hammer

http://www.datasheetlib.com/datasheet/581475/eac1420sp_cutler-hammer.html

There are different model numbers depending on the range of current you need to monitor.

Hope this helps,
