AD5755 output current has three mode: 0-20mA, 4-20mA, and 0-24mA.
as I know, normally industry applications are used the 0-20mA or 4-20mA.
What kind application or sensors is needed high current up to 24mA?
Thank you very much.
It really depends on the customer's application, there's no definite answer.
Another reason is to allow for alarm currents in the system:
This means in a FAULT situation, the sensor will control the DAC to decrease the supply current to 3.2mA or increase to 22.8mA or 24mA. This is a standard property of the 4-20mA current loop.
Hopefully this helps.
Apologies for my delay,
Most systems will have sensors that work within 4-20mA but sometimes there are other systems/applications that exceed this range.
For example, the sensor may not be suitable for a two-wire loop powered application.
The ADI Industrial DAC Portfolio provides 0-20mA and 0-24mA for these applications.
Thank you for your reply.
May I know what kind sensor work on 0~24mA spec that over 0~20mA spec?
