InLink-TC is a HART protocol modem that modulates logic level 1200 BAUD serial data to a HART loop, and demodulates received HART data providing a 1200 BAUD serial bit stream. InLink-TC interfaces to standard 3.3V to 5V logic and includes loop transformer isolation eliminating loop connection polarity and grounding  issues.  Adding only RS232 transceivers and a power supply make a complete RS232 to HART interface.  The InLink small package size simplifies integration into your design.
