Sitran P300 managing

Good afternoon to all,

I want to ask an informations about a Sitrans P300 pressure cabling and managing by S7-1500 PLC. I've a P300 with 4-20mA Hart interface. Can I connect it on a standard AI current card to manage only the current signal or I need a AI HART card?

Thanks

Hello biagiodim;

All HART-enabled transmitters allow the Primary Variable selected to be read out as a 4-20 mA signal if you choose to not use HART communications.

"The transmitter emits the output current according to the device variables selected as primary variable (PV). The operating range of the current lies between 4 mA and 20 mA."

- Sitrans P300 with HART communication:

You use the P300 keyboard to select which of the measured values is used as Primary Variable:

"The following device variables are available:

• Pressure

• Sensor temperature

• Electronics temperature

• Pressure (untrimmed)"

Hope this helps,

Thanks Daniel,

so, I can use a standard AI card. Without the Hart interface, Do I need an external power to the sensor?

Thanks

Thanks,

then, for example, with an ET200SP and AI card 6ES7134-6GD01-0BA1 + Base Unit 6ES7193-6BP00-0BA0, can I power on and manage the 4 AI signals of 4 Sitrans P300 measuring units?

Or to manage 8AI with 6ES7134-6GF00-0AA1 + Base Unit 6ES7193-6BP20-0BA0 (attached image)?

Thanks
