Rockwell Automation 937CU-AIHLP-DC1 HART Loop Converter Installation Instructions - Manual (Page 8)

The device supplies field devices and can be connected in parallel to existing HART circuits.
The device analyzes up to four HART variables (PV, SV, TV, QV). Three HART
variables can be transformed into varying current signals from these four HART
variables. These signals are used to display the values via the analog inputs of the
process control system.
The device is easily configured by the use of keypad or with the FDT configuration
software.
In addition to the current outputs, the device has two changeover contacts. These
changeover contacts can be programmed so that the changeover contacts function as
trip values for the HART variables
