EHELP: Can the ECT-DIN, be configured for a 4-20mA input and 4-12mA split range output?

EHELP: Can the ECT-DIN, be configured for a 4-20mA input and 4-12mA split range output?

Q. Can the ECT-DIN, configured for 4-20mA input and 4-20mA output, be calibrated to give 4-12mA output when the input is 4-20mA so that the output is 1/2 the input? We have a radio I/O signal that is scaled to 4-20mA for 0-65, 535raw units. When sent to the PLC over Modbus, it can't be read properly since the maximum register value size for the PLC is limited to 32767.

EHELP: Application for an Analog Splitter

EHELP: Application for an Analog Splitter

Q. I have an application that requires an analog splitter. The single input signal to the splitter comes from a transducer, and the transducer requires loop power. The two outputs are going to an active analog monitoring card on a PLC, which provides power to the connected 4-20mA signals. Is the ECT what I need?

EHELP: What are the advantages and limitations of HART protocol or an instrument with embedded MODBUS communication?

EHELP: What are the advantages and limitations of HART protocol or an instrument with embedded MODBUS communication?

Q: What are the advantages and limitations of HART protocol or an instrument with embedded MODBUS communication? How many instruments can the HCS interface in the same loop? Are we able to read/write the five instruments at the same time using HART?
