EHELP: Applying the SIX 2-wire Signal Isolator and Converter

EHELP: Applying the SIX 2-wire Signal Isolator and Converter

Q: I am evaluating the SIX 2-wire Signal Isolator and Converter. Is this device auto-calibrated or will we need to calibrate it ourselves? Does it require two separate power supplies? The specs state that the output is loop powered but I am not clear on the input. Also, is it a problem if we supply both the input and output with the same power source?  In our case, it would be the 53.5VDC power supply in the loop currently.  We would need to run a parallel path. The input is intended to be a 4-20mA.

EHELP: Using the TRY or RBX to Get Temperature Measurements of Generator Windings

EHELP: Using the TRY or RBX to Get Temperature Measurements of Generator Windings
Q: We have been using your SPA series temperature transmitters in our hydroelectric power plants with excellent results. These devices have high protection against electromagnetic interference. We would like to purchase temperature transmitters for head mounting and rail mounting that have the same high level of isolation and protection against electromagnetic interference. The sensors are Cu10 three wires and they give the temperature of generator windings in the hydroelectric power plant.

EHELP: Converting Three Analog Signals to HART Protocol

EHELP: Converting Three Analog Signals to HART Protocol

Q: You have a product called HART Interface Module that will pull the 2nd, 3rd and 4th HART variables from a smart HART transmitter and create one 4-20mA signal for each. Do you have or know of an instrument that will take three 4-20mA signals into it and place them on one 4-20mA signal as the 2nd, 3rd and 4th variable? I would like to read three transmitters on one 4-20mA signal by reading the variables on my DCS System.
