Question

Hi.

I configured the TRB141 like slave modbus and the analog input is configure like current loop input. When my master modbus ask to 141 register, the TRB141 response with this value: 2470, and in the TRB141 status, the analog current loop input values is 7.4mA (21.1%).

When the analog input is configure in Volt, my master modbus ask to 141 register and the TRB141 response this value, 10340 and in the TRB141 status of analog input in Volt is 10.34V

 When the analog input is configured like current loop, What does mean this value in the register 141 modbus? How can I convert this value in mA?

Thanks and excuse me for my english.

Hello,

Thank you for contacting.

This feature for conversion is not available in TRB141 . This is available in Rut955
