Hello yanikita, If you have 4-20 mA AI and you want to sellect the suitable AI module , you should first know if your transmitter is 4-wire or 2-wire. For 4-wire transmitter, if you used 6ES7 331-7KF02-0AB0, then you should use an external power supply for your transmitter. I mean by external power supply that it won't be powered from the AI module. Look on the attached document. For 2-wire transmitter, there's no need for external power supply.

My sensors are 4wire transmitters so it will match with the AI card mentionned above. Thanks for your help and advises. Yanikita |

Hello yanikita, Another small thing. If you would like to save some money, I think it will be better to use AI/AO module. Siemens have two AI/AO module: 6ES7334-0CE01-0AA0 SIMATIC S7, ANALOG INPUT/OUTPUT SM 334, NON-ISOLATED, 4 AI/2 AO, 1 X 20 PIN, REMOVE AND INSERT WITH BACKPLAIN BUS 6ES7334-0KE00-0AB0 SIMATIC S7-300, ANALOG MODULE SM 334, OPTICALLY ISOLATED, 4AE/2AA, 12 BIT, 0-10V F. PT100 (CLIMAT RANGE -120 - 155 DEGR.) AND 10 KOHM MEASURING RANGE, 1 X 20 PIN So you can use one of the above two modules. Regards, |
