InLink-TC is a HART protocol modem module that modulates logic level 1200 BAUD serial data onto 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 only requires 3 control lines; transmit, receive, and request-to-send (RTS). InLink-TC is a complete HART modem - adding only RS232 transceivers and a power supply makes an RS232 to HART interface and an effective way to evaluate the module. Loop transformer isolation eliminates loop connection polarity and grounding  issues and an internal 3V regulator and logic level shifters ensure consistent operation over a wide operating voltage range.

The InLink-TC small package size further simplifies integration into your design.
