How to Use Acromag 600T Series Isolated Transmitters Application Note
Re-transmitting a signal from a two-wire loop to a second location.
Splitting a signal from a two-wire loop: two outputs for different locations.
Retransmitting a signal output from a controller or a D/A card.
Low-cost, channel-to-channel isolation of 4-20mA signals for controllers.
Powering field transmitters (2-wire) and providing low-cost isolation of 4-20mA signals for controllers.
Require 4-wire isolators for input and output signals for controller. Built-in excitation supply needed for some field 2-wire devices.
Require a 4-wire isolator “splitter” to excite a field device and re-transmit 4-20mA to two locations.
Use additional 633T units for re-transmitting to more locations. Install inputs in series with primary 4-20mA loop or the re-transmitted loops as required.
Require 4-wire isolators to retransmit a 4-20mA signal to three locations.
